Q. Function of Adenosine in brain?
Adenosine has four different receptor subtypes (A1, A2A, A2B and A3). Adenosine A2A receptors are concentrated in striatum. Adenosine receptor modulation is one of the most important modulatory mechanisms of altering the level of consciousness.
Neurotensin
Neurons containing neurotensin (NT) are concentrated in the hypothalamus, striatum, amygdala. Receptors are localised in basal forebrain cholinergic neurons, dopaminergic nuclei and hypothalamus.
