Topic: stimulus-response association

Perceptual decision-making involves combining sensory evidence with available choices to arrive at an appropriate action to report the choice. When sensory evidence and potential actions to report choice are simultaneously available, neural activity in dorsal premotor (PMd) and lateral intraparietal (LIP) cortices covary with sensory evidence and choice. However, when sensory evidence and possible actions are separated in time, PMd and LIP show action selection related responses and only when the stimulus-response relationship is apparent. Thus, these areas are largely involved in action selec
