oxytocin recreational drug esidrix

► Long term neuroadaptations in oxytocin systems may explain how social behavior is adversely affected by long-term drug abuse. Oxytocin can advance the ovulatory luteinizing hormone surge, though the importance of this is not clear.The human OT gene, located on the short arm of chromosome 20 (20p12.2) in the vicinity of the AVP gene, consists of three exons and two introns Synthesis and release of OT changes according to sexual maturation, ovarian cycle, pregnancy, parturition, and lactation OT is produced in specific hypothalamic neurons present within the supraoptic and paraventricular nuclei of the hypothalamus. Furthermore, OT in cerebrospinal fluid markedly increases after copulation.We use cookies to help provide and enhance our service and tailor content and ads.

The burst of circulating OT induces milk ejection via contraction of the network of myoepithelial cells that surrounds mammary gland milk ducts. In contrast to the highly coordinated activity of OT neurons during lactation, the phasic bursts of AVP neurons are not temporally coordinated between individual neurons, and each neuron follows its own pattern controlled by an intrinsic rhythm generator. Is anyone else interested in the recreational potential of Oxytocin, the hormone released during sex? Upon activation by either an increase in blood osmolality or a decrease in blood pressure, AVP neurons display a phasic firing pattern of activity. Pulse frequency as well as pulse duration increases during spontaneous labor. This pattern is characterized by individual bursts of activity that alternate with periods of silence, each lasting 20–40 sec. Whether this increased activity of OT neurons initiates, or is stimulated by, parturition has remained unclear. Early research in this field indicated that exogenous oxytocin administration can prevent development of tolerance to ethanol and opiates, the induction of stereotyped, hyperactive behavior by stimulants, and the withdrawal symptoms associated with sudden abstinence from drugs and alcohol. The drug provides pain relief by acting on opioid receptors in the spinal cord, brain and possibly in the tissues directly. Brain oxytocin systems exhibit profound neuroplasticity and undergo major neuroadaptations as a result of drug exposure. Systemic OT can reverse the inhibitory effects of chronic fluoxetine, an SSRI.

In addition, these neurons are synaptically connected via an intrahypothalamic network as well as by afferences from a large number of limbic and sensory structures. An action potential is a short-lasting reversal of the electrical potential across the cell membrane.

Systemic or icv injections of OT facilitate copulation in male rats, and icv injections of an OT antagonist impair or abolish copulation. This neuropeptide, known commonly as a love drug, may be of use in treating such disorders. You must check to make sure that it is safe for you to take oxytocin with all of your drugs and health problems. In contrast to suckling, which induces short bursts of activation that are punctuated by relative silence, the preceding stimuli lead to a continuous activation of OT neurons.The patterns of electrophysiological activity displayed by AVP neurons differ very markedly from those of OT neurons. This is promoted by a large increase in oxytocin receptor expression in lactotrophs (cells secreting prolactin) at the end of pregnancy, but depends on withdrawal of inhibition by dopamine.
