a physiologically active substance that is produced by special neurons—the neurosecretory cells.

Like a mediator substance (chemical transmitter), a neurohormone is released by nerve endings, but in contrast to the first, a neurohormone is secreted into the blood or tissue fluid. Such secretion into the body fluids is characteristic of hormones. Neurohormones, for example, vasopressin, oxytocin, and the adenohypophysiotropic hormones, have been discovered in many vertebrates and in many invertebrates, including mollusks, worms, and arthropods. Chemically, the majority of neurohormones are peptides; some are catecholamines. Biosynthesis of peptide neurohormones occurs in the endoplasmic reticulum of the cell body of the neuron, The peptides are packaged in the Golgi complex and are subsequently transported along the axon to the nerve endings. In the mammalian brain the neurosecretory cells of the hypothalamus are a source of neurohormones. Neurohormones regulate the activity of the cells of some endocrine glands and influence the cells of other organs.

Both AMI and depression could lead to the elevation of neurohormone and increase the levels of circulating inflammatory cytokines.
Twelve participants with and without chronic pain and PTSD were included in this study of the effect of a single session of peak cardiopulmonary exercise testing (CPX) on plasma neurohormone levels (NPY, ALLO, cortisol, DHEA) and pain sensitivity.
Oxytocin is produced within the hypothalamus and is mediated by other neurohormones. The full effects of this naturally produced hormone are complex and still not fully understood.
A series of key neurohormones affect cardiac function in relation to HF: chiefly noradrenaline, angiotensin II, aldosterone and endothelin.
Pressure overload and ventricular volume expansion are the causes of high levels of this cardiac neurohormone. Hence, NPs can predict diastolic dysfunction increasingly in patients with either symptomatic or asymptomatic diastolic abnormalities.
In 2003, Odendaal and Meintjes (15) first showed that human-dog affiliative behavior (quiet play with the dog involving talking, stroking, and petting the dog with the human subject's attention focused completely on the dog) produced a significant change in neurohormones related to stress reduction: increases in beta endorphin, oxytocin (OXT), prolactin, dopamine, and decreases in cortisol.
Music has the power to induce and modulate different emotional states (these states are accompanied by the release of neurohormones in the affected brains).
Function of cardiac fibroblasts is modulated by diverse environmental stimuli in the remodeling heart, such as ischemia, mechanical stretch, neurohormones and oxygen stress.
[40] Piracetam and its derivatives interact with numerous receptors in the brain and modulate (stimulating and/or inhibiting) the post-synaptic signals, processes involving neurotransmitters and neurohormones. This action may be the result of an impact on the processes of cognition and behavioural neuroscience.
