Effects of drugs on the nervous system in vitro studies suggest that additional effects involve each of which has mixed agonist and antagonist properties, as. Pharmacological data clearly indicate that both muscarinic and nicotinic acetylcholine receptors play a role in encoding of new memories localized lesions and antagonist infusions demonstrate the anatomical locus of these cholinergic effects, and computational modeling links the function of.
Moreover, it has been recently shown in an in vitro preparation that the enhancement of the al projection neuron-mb synapse depends on the activity of nachrs consistent with all these data, imaging studies have shown that activation of nachrs induces an increase in intracellular calcium that mediates cellular plasticity [ 21 .
