Crossed surround inhibition feedforward

Summary[edit]

Description
English: A schematic representation of the manner in which the contrast enhancing and integrative functions of crossed surround inhibition may be instantiated via direct callosal activation of GABAergic interneurons. Pyramidal tract cells are shown in black. The pyramidal cells labelled P are subject to focused excitatory drive. The red cells are inhibitory interneurons. Callosal projections (excitatory) are shown in cyan. The inhibitory influence upon pyramidal tract cells in the surround region of the opposite hemisphere (“excitatory fringe”) in this case arises from local feed-forward inhibitory circuits. A key assumption is that the inter-hemispheric interactions arising from this configuration can be reciprocal (e.g. Bianki and Makarova, 1980; O’Hashi et al., 2018).
