Abstract
Cats trained in a classical differential conditioning situation exhibited the same pattern of EEG desynchronization during both the reinforced (CS) and non-reinforced (DS) stimuli, although they responded only to the former. In contrast, thalamically induced electrocortical recruiting responses, evoked prior to stimulus onset, were differentially affected; recruiting was attenuated by the CS but not by the DS. The results demonstrate the sensitivity of recruiting responses in the absence of gross EEG changes, and suggest that reticulothalamic interactions may comprise part of the neural substrate of attention.
