WebINTRODUCTION. The emerging field of homeostatic plasticity can be subdivided into three areas that are defined by the way in which a cell responds to a perturbation, namely the homeostatic control of intrinsic excitability (1–7), neurotransmitter receptor expression (3, 7), and presynaptic neurotransmitter release (8–12).Together, these areas represent a … Web2 days ago · The study indicates that loss of cognitive function from obstructive sleep apnea can occur as early as middle age in men.
