  • This chapter will concentrate on the mechanisms by which drugs alter neurotransmission of relevance to the treatment of psychiatric disorders. ■ The major site of action for drugs used in psychiatry is the synapse and in particular those utilising amines or amino acids as neurotransmitters. ■ The majority of the drugs act either presynaptically to influence levels of the neurotransmitter in the synaptic cleft, or by altering the functional state of the postsynaptic receptors.

  • It apparently does this by inhibiting the release of neurotransmitters, chemicals that carry nerve impulses from one neuron to the next. (10) Like many other agents that affect neuron firing, adenosine must first bind to specific receptors on neuronal membranes.

  • Chronic consumption For benefits of chronic alcohol consumption, see page 187. Central nervous system. The development of dependence on alcohol appears to involve alterations in central nervous system neurotransmission. The acute effect of alcohol is to block NMDA receptors for which the normal agonist is glutamate, the main excitatory transmitter in the brain. Chronic exposure increases the number of NMDA receptors and also 'L type' calcium channels, while the action of the (inhibitory) GABA neurotransmitter is reduced.

  • The theory of neurohumoral transmission received direct experimental validation nearly a century ago (see von Euler , 1981 ), and extensive investigation during the ensuing years led to its general acceptance. Nerves transmit information across most synapses and neuroeffector junctions by means of specific chemical agents known as neurohumoral transmitters or, more simply, neurotransmitters.

  • Patients affected by bleeding disorders present a wide spectrum of clinical symptoms that vary from a mild or moderate bleeding tendency to significant episodes. Women with inherited bleeding disorders are particularly disadvantaged since, in addition to suffering from general bleeding symptoms, they are also at risk of bleeding complications from regular haemostatic challenges during menstruation, pregnancy and childbirth.

  • This diverse collection of research articles is united by the enormous power of modern molecular genetics. Every author accomplished two objectives: (1) making the field and the research described accessible to a large audience and (2) explaining fully the genetic tools and approaches that were used in the research. One fact stands out - the importance of a genetic approach to addressing a problem. I encourage you to read several chapters.

  • Receptors for the key female reproductive hormones, estrogens, are found throughout the entire brain including prefrontal cortex, hypothalamus, neocortex, hippocampus, amygdala, striatum, and brain stem. The neurotransmitter systems involved in depression (serotonin, norepinephrine, dopamine, cetylcholine, GABA, glutamate) are regulated by the action of estrogen. Research suggests that women may have increased susceptibility to depression and mood disorders during two key lifecycle transitions: pregnancy and the postpartum period, and perimenopause.

  • Central Mechanisms The Spinal Cord and Referred Pain The axons of primary afferent nociceptors enter the spinal cord via the dorsal root. They terminate in the dorsal horn of the spinal gray matter (Fig. 12-3). The terminals of primary afferent axons contact spinal neurons that transmit the pain signal to brain sites involved in pain perception. When primary afferents are activated by noxious stimuli, they release neurotransmitters from their terminals that excite the spinal cord neurons. The major neurotransmitter they release is glutamate, which rapidly excites dorsal horn neurons.

  • Other Diseases The power and versatility of gene transfer approaches are such that there are few serious disease entities for which gene transfer therapies are not under development. Besides those already discussed, other areas of interest include gene therapies for HIV and for neurodegenerative disorders.

  • Understanding of the neuroendocrine system provides an insight into a wide range of bodily and mental processes. Neuroendocrinology and Behavior brings its readers a concise guide to up-to-date knowledge on the function of the endocrine glands and organs in association with neurotransmitters, neuropeptides, and behavioral manifestations. Various forms of stress response, e.g. anxiety and cognitive changes, have been intrinsic to both ourselves and other species.

  • The second, developed through narcissism and the constitution of the ego, comes from identification with the image seen. Thus, in film terms, one implies a separation of the erotic identity of the subject from the object on the screen (active scopophilia), the other demands identification of the ego with the object on the screen through the spectator's fascination with and recognition of his like. The first is a function of the sexual instincts, the second of ego libido. This dichotomy was crucial for Freud.
