Abstract

ey words: end-stopping; length tuning; intracellular recording; V1; striate cortex; end inhibition; conductance; receptive field The nature of cortical interconnections and the computations they subserve comprise a f undamental problem in cortical physiology. In primary visual cortex, such cortical interconnectivity is presumed to be responsible for local processing and gain control for stimuli within the classical receptive field (Bauman and Bonds, 1991; DeAngelis et al., 1992; Heeger et al., 1996; Carandini et al., 1999), as well as for interactions between stimuli within the classical receptive field of a neuron and stimuli outside the classical receptive field (Maffei and Fiorentini, 1976; Nelson and Frost, 1978; Kapadia et al., 1995; Levitt and Lund, 1997; Polat et al., 1998; Somers et al., 1998). One of the most robust examples of cortical processing in primary visual cortex is length tuning or end inhibition. Hubel and Wiesel (1965) first described complex cells in whi
