(A) Large-scale neural models of visual short-term memory. FS, D1, D2, and FR represent distinct neuronal populations within PFC (see Tagamets and Horwitz, 1998 for details). Abbreviations: LGN, lateral geniculate nucleus; V1–V2, primary and secondary visual cortex; V4, extrastriate visual cortex; IT, inferior-temporal cortex; PFC, prefrontal cortex. (B) Basic neuronal population unit (Wilson-Cowan) of the visual model of short term memory. Each unit has an excitatory (E) and an inhibitory (I) element. Dark arrows represent excitation and the red arrow represents inhibition. Adapted from Horwitz et al. (2005).
