  • 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.

  • Every day veterinarians in practice are asked to treat pets exhibiting problem behaviors. In the last several years pharmacologic treatments of behavior have made significant advances and can serve as a critical part of therapy. Veterinary Pscyhopharmacology is a complete source of current knowledge on the subject of pharmacologic behavior modification that veterinarians can turn to for the answers they need.

  • 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.

  • Neural Control The small intestine and colon have intrinsic and extrinsic innervation. The intrinsic innervation, also called the enteric nervous system, comprises myenteric, submucosal, and mucosal neuronal layers. The function of these layers is modulated by interneurons through the actions of neurotransmitter amines or peptides, including acetylcholine, vasoactive intestinal peptide (VIP), opioids, norepinephrine, serotonin, ATP, and nitric oxide. The myenteric plexus regulates smooth-muscle function, and the submucosal plexus affects secretion, absorption, and mucosal blood flow.

  • The impact of perinatal mental health problems on infants has been studied in HIC, mostly in terms of neuro-psycho-behavioural variables, which are likely to apply in LMICs as well. Infants of depressed mothers show dysregulations affecting their behavior and physiology, thought to be derived from a prenatal exposure to a biochemical imbalance in their mothers (48, 70). Newborns of depressed mothers also have neurotransmitter imbalances (e.g., higher cortisol and lower dopamine and serotonin levels), are described as physiologically less mature (e.g.

  • Estrogen receptors and serotonin receptors coexist in cells in a wide variety of tissues, and this critical review of the literature suggests that many of E2's effects may be medi- ated by changes in the actions of serotonin (5HT). Serot- onin is usually considered to be a neurotransmitter, but surprisingly, only 1% of serotonin in the human body is found in the CNS [4].
