Resumen:

This chapter uses a highly simplified sensory discrimination task to show that the comparison between stored and ongoing sensory information takes place in a distributed fashion. There is also a continuum between sensory-and motor-related activities. Neurons from areas central to the S1 cortex do not simply wait for a signal encoding decision; rather, they participate at every step of its generation by combining working memory and sensory inputs. This process is carried out by two complementary neuronal responses. This dual representation is found in all areas central to the S1 cortex examined in this task, and might serve to compute optimally the entire perceptual process of the task. This coding scheme has also been found in some cortices of monkeys performing tasks that require behavioral decisions based on a comparison operation. © Oxford University Press, 2013.
