The non-motor symptoms that emerge secondary to gastritis diet ïåðåâîä÷èê misoprostol 200 mcg on-line dopaminergic therapy encompass several domains helicobacter gastritis diet safe 100 mcg misoprostol, including neuropsychiatric, autonomic, and sleep. In addition, compulsive behaviors, such as pathological gambling, hypersexuality, shopping, binge eating, and punding, have been shown to have a clear association with dopaminergic medications. Treatment side e ects on the autonomic system include nausea, orthostatic hypotension, and constipation. Sleep disturbances include fragmented sleep, nighttime sleep problems, daytime sleepiness, and sleep attacks. Recognizing the non-motor symptoms that can arise speci cally from dopamine therapy is useful to help optimize treatment regimens for this complex disease. Clozapine has demonstrated e cacy in a double-blind placebo-controlled Hallucinations and psychosis have long been known to be trial ; however, in clinical practice quetiapine is preferred, associated with dopaminergic therapy.

When the action potential reaches the Chemical Transmission axon terminal, the signal is now strong enough to cause Most neurons send a signal to the cell across the synapse by depolarization of the presynaptic membrane and to trig releasing neurotransmiters into the synaptic clef. The arrival of the action po transferred to the next neuron across the synaptic clef, tential at the axon terminal leads to the depolarization of the the gap bet n neurons at the synapse. The opening of these channels triggers small vesicles containing neurotransmiter to fuse with the membrane at T A K E H O M E M E S S A G E S the synapse and release the transmiter into the synaptic the presynaptic cell is located before the synapse with clef. The transmiter difuses across the clef and, on reach respect to information fow; the postsynaptic cell is ing the postsynaptic membrane, binds with specifc recep located after the synapse with respect to information tors embedded in the postsynaptic membrane (Figure 2. Nearly all neurons are both pre and postsynaptic, Neurotransmiter binding induces a change in the receptor, since they both receive and transmit information. The electrical gradient results from the asymmetrical Hyperpolarization of the postsynaptic neuron produces an distribution of ions across the membrane. Synaptic Transmission | 33 Neurotransmitters Synapse Postsynaptic The process just described brings us Presynaptic neuron neuron (axon terminal) (spine on to a hot topic of the popular press: dendrite) neurotransmiters. While you may have heard of a few of them, more than 100 neurotransmiters have ben identifed. Synaptic Action cleft potential It is synthesized by and localized within the presynaptic neuron, Action potential depolarizes the Ca2+ causes vesicles to bind with 1 2 and stored in the presynaptic terminal membrane, which causes cell membrane Ca2+ to ow into the cell terminal before release. An other category of neurotransmiters, called biogenic amines, includes do pamine, norepinephrine, and epi nephrine (these thre are known as the catecholamines), serotonin (5-hydroxytryptamine), and hista mine. When the action potential invades the axon terminals, it causes voltage-gated Ca2+ channels to open (1), which triggers vesicles to bind to the presynaptic large group of neurotransmiters membrane (2). Neurotransmitter is released into the synaptic cleft by exocytosis and diffuses consists of slightly larger molecules, across the cleft (3). Binding of the neurotransmitter to receptor molecules in the postsynaptic the neuropeptides (made up of strings membrane completes the process of transmission (4). More than 100 neu ropeptides are active in the mamma lian brain, and they are divided into fve groups: mammary functions and has ben tagged the 1. This group includes “love hormone” for its role in pair bonding and substance P, which afects vasoconstriction and is a maternal behaviors; the later is an antidiuretic spinal neurotransmiter involved in pain. The efects of a neurotransmiter also depend on the connections of the neurons that use Vm Presynaptic the transmiter. Nevertheless, neurotransmiters can be terminal 0 classifed not only biochemically but also by the tpical efect that they induce in the postsynaptic neuron. Some neurotransmiters act directly to excite or inhibit a postsynaptic neuron, but After transmitter release other neurotransmiters act only in concert with other Excitatory factors. Tese are sometimes referred to as conditional Vm postsynaptic potential neurotransmiters; that is, their action is conditioned on 0 the presence of another transmiter in the synaptic clef or activit in the neuronal circuit. Tese tpes of mecha –70 nisms permit the nervous system to achieve complex modulations of information processing by modulating Transmitter neurotransmission. The binding of neurotransmitter to the postsynaptic membrane re Neurotransmitters after ceptors changes the membrane potential (Vm). These postsynaptic Release potentials can be either excitatory (depolarizing the membrane), as shown here, or inhibitory (hyperpolarizing the membrane). Following the release of neurotransmiter into the synap tic clef and its binding with the postsynaptic membrane receptors, the remaining transmiter must be removed in the stress response, and somatostatin, an inhibitor to prevent further excitatory or inhibitory signal trans of growth hormone. This group is so named for its simi reuptake of the substance back into the presynaptic ter larit to opiate drugs, permiting the neuropeptide to minal, (b) by enzymatic breakdown of the transmiter in bind to opiate receptors. It includes the endorphins the synaptic clef, or (c) merely by difusion of the neu and enkephalins. Neurotransmiters that are removed fom the syn Some neurons produce only one tpe of neurotrans aptic clef by reuptake mechanisms include the biogenic miter, but others produce multiple kinds of neurotrans amines (dopamine, norepinephrine, epinephrine, hista miters. The reuptake mechanism is medi released together or separately, depending on the condi ated by active transporters, which are transmembrane tions of stimulation. For example, the rate of stimulation proteins that pump the neurotransmiter back across the by the action potential can induce the release of a specifc presynaptic membrane. Tese the Role of Glial Cells | 35 autoreceptors are located on the presynaptic terminal synapses also have some limitations: They are much less and bind with the released neurotransmiter, allowing the plastic than chemical synapses, and they cannot amplif a presynaptic neuron to regulate the synthesis and release signal (whereas an action potential that triggers a chemi of the transmiter. They are found on dendrites and at specializations called gap junctions, and the cytoplasms axon terminals but can also be found on the neuronal of the to neurons are essentially continuous. As a result, neurotransmitters from the presynaptic neuron and the binding of those neurotransmitters on the postsynaptic the to neurons are iopotential. Under most circumstances, the (a) active reuptake back into the presynaptic terminal, communication is bidirectional; however, so-called rec (b) enzymatic breakdown of the transmitter in the tifing synapses limit current fow in one direction, as is synaptic cleft, or (c) diffusion of the neurotransmitter tpical in chemical synapses. Groups of neurons with these specialized channels in gap junctions that connect the synapses can activate muscles quickly to get the animal cytoplasm of one cell directly to the other. For example, the well-known tail fip refex of crayfshes involves powerful rectifing electri cal synapses. Electrical synapses are also useful when groups of neurons should operate synchronously, as with the Role of Glial Cells some hypothalamic neurosecretory neurons. Electrical The other tpe of cell in the nervous system is the glial cell (also called neuroglial cell). The term neuroglia means, literally, “nerve glue,” because anato mists in the 19th century believed that the main role of neuroglial cells in the nervous system was structural support. While glial cells do provide structural support, they also carry out other roles in the nervous system, such as helping to form the blood–brain barrier and aid Pore Cytoplasm of ing in the sped of information transfer. Electrical synapses are formed by gap junctions, places where The central nervous system has thre main tpes of gli multiple transmembrane proteins in the pre and postsynaptic neurons connect to create pathways that connect the cytoplasms al cells: astrocytes, microglial cells, and oligodendrocytes of the two neurons. In vitro studies indicate that they respond to and Blood vessel release neurotransmiters and other neu Astrocyte roactive substances that afect neuronal activit and modulate synaptic strength. More recently, in vivo studies found that when astrocyte activit is blocked, neural activit increases. This fnding supports Central Axon the notion that neural activit is moderat nervous ed by astrocyte activit (Schummers et al. It is hypothesized that astrocytes either directly or indirectly regulate the reuptake of neurotransmiters. They are Microglial cell phagocytes, literally devouring and remov ing damaged cells. Unlike many cells in the central nervous system, microglial cells can proliferate even in adults (as do other Peripheral glial cells). Oligodendrocytes their cell membranes around the axon in and Schwann cells produce myelin around the axons of neurons—oligodendrocytes a concentric manner during development in the central nervous system, and Schwann cells in the peripheral nervous system. The cytoplasm in that por tion of the glial cell is squezed out, leaving primarily the lipid bilayer of the glial cell or radially symmetrical forms; they surround neurons sheathing the membrane.

Other neural circuits the Bigger Picture throughout the nervous system perform other functions. In general though, neural circuits share some basic Until now, we have ben talking about only one or to features. This approach is useful in understanding evaluate the input either at a synapse or within one or a how neurons transmit information, but it fails to illumi group of neurons (local circuit neurons), and they convey nate how the nervous system and the brain function. This is what happens with learning connectivit in the nervous system in order to map out and during development. For example, the visual system is com rons are extensively connected in both serial and parallel posed of many diferent neural circuits organized in both circuits. A single cortical neuron is likely to be innervated hierarchical and parallel processing streams to enable by.

We must put ourselves in their place and see what happened from the victim’s perspective. Before he did so, someone switched the sugar for a poison of the same colour and consistency. In order to arrive at that conclusion, we put ourselves in his shoes, recognizing what he knows and doesn’t know, and seeing that he had no intention of hurting his friend. Peter takes the bowl and replaces the sugar with poison because he wants to kill his friend. He spoons the poison into his friend’s tea but it has no effect on him, and his friend walks away alive and kicking. However, we almost all believe that Peter did the wrong thing, that his action is reprehensible. The theory of mind is the result of the articulation of a complex cerebral network, with a particularly important node in the right temporoparietal junction. As its name suggests, it is found in the right hemisphere, between the temporal and parietal cortices, but its location is the least interesting thing about it. Cerebral geography is less important than the fact that a function’s location in the brain can be a window to inferring the causal relationships in * its workings. If our right temporoparietal junction were to be temporarily silenced, we would no longer consider Joe and Peter’s intentions when judging their actions. If that region of our brains is not functioning as it should, we would believe that Joe did wrong (because he killed his friend) and that Peter did right (because his friend is in perfect health). We wouldn’t take into consideration that Joe didn’t know what was in the sugar bowl and that Peter had failed to carry out his macabre plan only through chance. These considerations require a precise function, the theory of mind, and without it we lose the mental ability to separate the consequences of an action from its network of intentions, knowledge and motivations. This example, demonstrated by Rebecca Saxe, is proof of a concept that goes beyond the theory of mind, morality and judgement. It indicates that our decision-making machinery is composed of a combination of pieces that establish particular functions. And when the biological support of those functions is disarmed, the way we believe, form opinions and judge changes radically. More generally, it suggests that our notion of justice does not result from pure and formal reasoning, but that instead it is conceived in a particular state * of the brain. But there is no need in fact to have very sophisticated brain-stimulating devices to prove this concept. The common image of the reality of justice being ‘what the judge ate for breakfast’ seems in fact to be quite true. This study of course cannot factor out the many variables that change between breaks such as glucose, or fatigue, or accumulated stress. But it shows that simple extraneous factors which condition the state of the judge’s brain have a strong influence on the outcome of court decisions. The inner battles that make us who we are Moral dilemmas are hypothetical situations taken to an extreme that help us reflect on the underpinnings of our morality. The most famous of them is the ‘trolley problem’, which goes like this: You are on a tram without brakes that is travelling along a track where there are five people. You are well acquainted with its functioning and know without a shadow of a doubt that there is no way to stop it, and that it will run over those five people. You can turn the wheel and take another track where only one person will be run over. In Brazil, Thailand, Norway, Canada and Argentina, almost everyone–young or old, liberal or conservative–chooses to turn it on the basis of a reasonable, utilitarian calculation. Yet experiments show that there is a minority of people who consistently decide not to turn the wheel. The dilemma consists in doing something that will provoke the death of one person or not doing anything to keep five people from dying. Some people could reason that fate had already chosen a path and that they shouldn’t play God and decide who dies and who lives, even when the maths favours that choice. They reason that we have no right to intervene, bringing about the death of somebody who would have been fine if not for our action. Now, another version of the dilemma: You are on a bridge from which you see a tram hurtling down a track where there are five people. You are completely sure that there is no way to stop it and that it will run over those five people. You know for certain that if you push him, he will die but he will also make the trolley go off the tracks and save the other five people. And the difference is perceived in a clear, visceral way, as if it were decided by our bodies. This is supported by our penal and social system–both the formal one and the judgements of our peers: neither would consider these two cases to be equal. Let’s imagine that we are alone, that the only possible judgement is our own conscience. The results are conclusive and universal: even completely alone, with no one watching, almost all of us would turn the wheel and almost no one would push the man from the bridge. Seeing this is not easy because it requires going against our intuitive body signals. But from a purely utilitarian perspective, from the motivations and consequences of our actions, the dilemmas are identical. Or we choose to let fate take its course because we feel that we do not have the moral right to intervene, condemning someone who was not destined to die. In order to exaggerate the contrasts between them, we present an even more far-fetched dilemma. There are five patients, each one with an illness in a different organ that can be solved with a single transplant that you know will undoubtedly leave them in perfect health. In this case, the vast majority of people presented with the dilemma would not take out the organs to save the other five, even to the point of considering the possibility aberrant. This third case again shares motivations and consequences with the previous dilemmas. The pragmatic doctor works according to a reasonable principle, that of saving five patients when the only option in the universe is one dying or five dying. What changes in the three dilemmas, making them progressively more unacceptable, is the action one has to take. The first act is turning a wheel; the second, pushing someone; and the third, cutting into people with a surgical knife. Furthermore, it seems innocuous and involves a frequent action unconnected to violence. On the other hand, the causal relationship between pushing the man and his death is clearly felt in our eyes and our stomachs. In the case of the wheel, this relationship was only clear to our rational thought. The first argument (five or one) is utilitarian and rational, and is dictated by a moral premise, maximizing the common good or minimizing the common evil. The second argument is visceral and emotional, and is dictated by an absolute consideration: there are certain things that are just not done. This specific action that needs to be done to save five lives at the expense of one is what distinguishes the three dilemmas. And in each dilemma we can almost feel the setting in motion of a decision-making race between emotional and rational arguments, a la Turing, in our brain. This battle that invariably occurs in the depths of each of us is replicated throughout the history of culture, philosophy, law and morality. One of the canonical moral positions is deontological–this word derives from the Greek deon, referring to obligation and duty–according to which the morality of actions is defined by their nature and not their consequences. In other words, some actions are intrinsically bad, regardless of the results they produce. Another moral position is utilitarianism: one must act in a way that maximizes collective wellbeing. The person who turns the wheel, or pushes the man, or slices open the flu sufferer would be acting according to a utilitarian principle. And the person who does not do any of those actions would be acting according to a deontological principle.
