In the adult nervous system, neurotransmitters act as chemical mediators of intercellular communication by the activation of specific receptors and second messengers in postsynaptic cells. This specialized role may have evolved from more primitive functions in lower organisms where these substances were used as both intra- and intercellular signalling devices. This view derives from the finding that a number of 'classical' neurotransmitters are present in primitive organisms and early embryos… CONTINUE READING
