TL;DR: Microelectrode multiunit mapping studies of parietal cortex in owl monkeys indicate that the classical “primary” somatosensory region (or “SI”) including the separate architectonic fields 3a, 3b, 1, and 2 contains as many as four separate representations of the body rather than one.

TL;DR: Functional visual projections can be routed into nonvisual structures in higher mammals, suggesting that the modality of a sensory thalamic nucleus or cortical area may be specified by its inputs during development.

TL;DR: In ferrets in which retinal projections are routed into the auditory pathway, visually responsive neurons in ‘rewired’ primary auditory cortex are also organized into orientation modules, showing that afferent activity has a profound influence on diverse components of cortical circuitry, including thalamocortical and local intracortical connections, which are involved in the generation of orientation tuning, and long-range horizontal connections which are important in creating an orientation map.

TL;DR: The somatotopic organization of the postcentral parietal cortex of the Old World monkey, Macaca fascicularis, was determined with multi‐unit microelectrode recordings and it is suggested that the representation in Area 3b is homologous to “SmI” (or “SI”) in non‐primates.

TL;DR: It is reported that this cross-modal projection and its representation in auditory cortex can mediate visual behaviour and gratings of different spatial frequencies can be discriminated by the rewired pathway, although the grating acuity is lower than that of the normal visual pathway.
