Dopamine is a neurotransmitter responsible for transmitting signals between neurons in the brain. Few neurons produce dopamine.The catecholamine neurotransmitter dopamine is not as plentiful as it has been conceived to be. In fact, it is so scarce, that only 0.3% of the brain’s millions of neur...
DA-mediated regulation of urinary activity is considered to occur through an interaction between midbrain DA neurons and the pontine micturition center. Here we show that DA is produced in the rat spinal cord and modulates the bladder reflex. We observed numerous tyrosine hydroxylase (TH)(+) ...

Dopamine is well recognized as a neurotransmitter in the brain, and regulates critical functions in a variety of peripheral systems. Growing research has a
Dopamine is a neurotransmitter in both central and peripheral nervous system. In the central nervous system dopamine is involved in regulation of: movements, emotional processing of sensory input, appetite, vomiting and secretion of anterior pituitary hormones. The most important peripheral effect of dop...
Although previous work has shown that performance on several schedules (e.g., continuous, low value ratios, variable interval) is relatively unaffected by accumbens DA depletions, the present data demonstrate that such depletions do produce a substantial and persistent impairment of progressive ratio ...
Convincing evidence has so far only been produced for the existence of one transmitter in the mammalian adrenergic nervous system, namely noradrenaline. It is still an open question, however, whether other adrenergic neurohormones exist. Among the possible candidates adrenaline and 3-hydroxytyramine (d...
Until the late 1950s, dopamine (DA) was believed to serve merely as a precursor in the synthesis of norepinephrine. Montagu (1957) and Weil-Ma l herbe et al. (1957) were the first to present evidence that DA is a normal constituent of the mammalian brain. The observation that in most...
The key feature of S–R habits is that they do not take into consideration the future outcomes produced by actions—but in many behavioral situations, those outcomes may be simply too remote in time to be relevant to DLS calculations. By contrast, VS neurons typically show more prolonged and...
Social play is a highly rewarding behavior displayed mostly during the juvenile period. We recently showed that vasopressin V1a receptor (V1aR) blockade in the lateral septum (LS) enhances social play in male juvenile rats, but reduces it in females. Here, we determined whether the LS-AVP sy...
