The hypothalamus is located below the thalamus and is part of the limbic system. [1] It forms the basal part of the diencephalon. All vertebrate brains contain a hypothalamus. [2] In humans, it is about the size of an almond. [3] The hypothalamus has the function of regulating certain metabolic processes and other activities of the autonomic ...
The hypothalamus uses somatostatin to tell the pituitary to inhibit somatotropin and to tell the gastrointestinal tract to inhibit various gastrointestinal hormones. There are various other inhibiting factors that also have tropic endocrine inhibition activity. Such activity is only one of many functions that they have (such as neurotransmitter ...
The cell bodies of these neurons are located in various nuclei of the hypothalamus or in closely related areas of the basal brain, mainly in the medial zone of the hypothalamus. [ 1 ] [ 2 ] All or most of the axons of the parvocellular neurosecretory cells project to the median eminence , at the base of the brain, where their nerve terminals ...
[4] [5] [6] GnIH and GnRH (gonadotropin releasing hormone) neurons exist in close proximity in the hypothalamus, which may enable the direct inhibition of GnRH neurons by GnIH. [7] GnIH enters the bloodstream via the hypothalamo-hypophyseal portal system, the vascular network supplying both the hypothalamus and the pituitary. [8]
The hypothalamus produces the hormones oxytocin and vasopressin in its endocrine cells (left). These are released at nerve endings in the posterior pituitary gland and then secreted into the systemic circulation. The hypothalamus releases tropic hormones into the hypophyseal portal system to the anterior pituitary (right).

The hypothalamus produces and releases gonadotropin-releasing hormone (GnRH). GnRH nudges the pituitary gland to produce luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Inhibitory control, also known as response inhibition, is a cognitive process – and, more specifically, an executive function – that permits an individual to inhibit their impulses and natural, habitual, or dominant behavioral responses to stimuli (a.k.a. prepotent responses) in order to select a more appropriate behavior that is consistent with completing their goals.
