✦ Synopsis
A truth table definition for neural inhibition is used to develop a model for stimulus specificity in a sensory system. An example from the mammalian visual system, that of orientation selectivity in visual cortex, is worked out in detail. Using the assumption that logical processing of signals may take place in a nerve cell's dendritic tree, a digital circuit is transformed into a neural model. An important feature of the model is an inhibitory neuron, termed an M-cell, which by its actions confers response specificity on neighboring principal cells. The M-cell is shown to have several properties in common with basket cells seen in cerebellar, hippocampal and cerebral cortex.
