Extended Data Fig. 3: Retinotopic organization and functional properties of single neurons across multiple visual areas.
From: Large-scale high-density brain-wide neural recording in nonhuman primates
a, Distribution of receptive fields (RFs) of 2729 visually responsive neurons across cortical depth from the 5-banks recording across multiple visual areas. Color scale represents cortical depth. b, Top-view of a, illustrating the progression of RFs across visual fields. RFs from the superficial and deeper part of the brain are demonstrated separately for clarity. c, Polar angle (theta) and Eccentricity (rho) of each RF’s geometric center across cortical depth. d, Left, heat map of evoked responses across drift directions of grating (vertical thickness is greater for less dense neuronal population). Color scale represents the magnitude of evoked responses. Right, direction index as quantified by the differences of responses to the preferred and its opposite direction divided by the sum of the two. In c and d, each neuron is plotted at its corresponding cortical depth. Horizontal lines denote the section of cortex where the center of RFs falls on Lower vertical meridians (LVM), horizontal meridian (HM), upper vertical meridian (UVM), and horizontal meridian (HM), respectively, superficial to deep. Putative visual areas are identified and labeled. LVF: lower visual field; UVF: upper visual field; FST: fundus of the superior temporal (FST) area. e, Polar angle (theta) and Eccentricity (rho) of each RF’s geometric center across cortical depth calculated using the first and second half of trials within a session, demonstrating stability of function properties of neurons recorded throughout a session.
