  • 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.

  • γ-Aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain where it regulates activity of neuronal networks. The receptor for glucagon-like peptide-1 (GLP-1) is expressed in the hippocampus, which is the center for memory and learning.

  • The tachykininergic neurotransmitters have been proved to be involved in the inflammatory progress and chronic pain in series of disease. The present study was undertaken to evaluate the levels of substance P (SP) and its receptors NK-1 receptor (NK-1R) in both serum and synovial tissues of hip joint from patients with different stages of DDH, and to detect the possible correlation of serum SP levels with pain sensation and dysfunction of the hip joint.

  • 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.

  • Các chất dẫn truyền khác Trong những năm gần đây, nhiều nghiên cứu đã cho thấy rằng phần lớn các nơron trung ương và ngoại biên có chứa 2 hoặc nhiều chất dẫn truyền, có thể được giải phóng ra cùng một lúc ở xinap khi dây thần kinh bị kích thích. Như vậy, ở hệ thần kinh thực vật, ngoài acetylcholin (ACh) và noradrenalin (NA), còn có những chất dẫn truyền thần kinh (neurotransmitters) khác cùng được giải phóng và có thể có vai trò như chất cùng dẫn truyền (cotransmitters), chất điều biến thần kinh (neuromodulators) hoặc...

  • 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.

  • 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.

  • 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.

  • 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.
