The central structure of the brain contains the thalamus, hypothalamus , and pituitary gland.
One theory is that light stimulates a part of the brain called the hypothalamus , which controls mood, appetite, and sleep.
Normally the hypothalamus coordinates the activity of the pituitary gland through the secretion of peptides and amines.
These regions are centred in the cerebellum, hippocampus, hypothalamus and basal ganglia.
The brain also links with endocrine gland chemical messengers through the hypothalamus and pituitary gland.
Hypothyroidism can also develop secondary to hypothalamic and pituitary disorders.
Amygdaloid nuclei and the hypothalamic structures are known to have intimate functional relationships.
Like others of these peptides, glucagon is expressed in the brain stem and hypothalamic neurons.
Common nervous system manifestations include facial palsies, and hypothalamic and pituitary lesions.
And oestriol is a measure of the function of the hypothalamic pituitary adrenal axis, or the HPA axis in the foetus.
