Local organization of the prefrontal cortex. A. No retinotopic map of visual space is present in dorsal posterior PFC, whose neurons do display strong selectivity for space. B. Some local organization and orderly progression of receptive fields is revealed in tangential electrode penetrations in the principal sulcus. C. Organization of activity across the depth of the PFC. Cue responses predominate in middle layers; delay period activity in upper layers; response activity in deeper layers of the PFC. Panel A based on Leavitt et al., 2018; panel B based on Arnsten et al., 2013; panel C based on Markowitz et al., 2015.
