[Activation of striatum cholinergic system improves attention to conditioned stimuli].

Activation and blockade of the dog striatal cholinergic system yielded data suggesting that the cholinergic system of the striatum takes part in regulation of attention to significant stimuli working through motor structures involved in indirect efferent pathways as well as through sensory systems, too. The two possible mechanisms of sensory regulation of the attention processes by the striatal cholinergic system have been outlined.
