摘要: In a typical sequential sensory discrimination task, subjects are required to make decision based on comparing stimulus against the memory trace left by previous stimulus. What is neuronal substrate for such comparisons and resulting decisions? This question was studied recording responses in variety of cortical areas awake monkeys (Macaca mulatta), trained carry out vibrotactile task. We describe methods analyse obtained during comparison phases findings from recordings secondary somatosensory area (S2). A subset neurons S2 become highly correlated with monkey's
