MORE than 30 years after Hubel and Wiesel1 first described orientation selectivity in the
mammalian visual cortex, the mechanism that gives rise to this property is still controversial …

Neurons in the visual cortex are selectively responsive to light or dark bars presented at
particular orientations1. On the basis of physiological data, this orientation selectivity is …

Orientation tuning of neurons is one of the chief emergent characteristics of the primary
visual cortex, VI (refs 1, 2). Neurons of the lateral geniculate nucleus, which comprise the …

SIMPLE cells within layer IV of the cat primary visual cortex are selective for lines of a
specific orientation. It has been proposed that their receptive-field properties are established …

In the primary visual cortex, the development of orientation selectivity is influenced by
patterns of neural activity. The introduction of artificially correlated activity into the visual …

NEURONS in the primary visual cortex respond selectively to the orientation of edges and
their direction of motion. Orientation preference is mapped in a systematic fashion across the …

The selectivity of neuronal responses arises from the architecture of excitatory and inhibitory
connections. In the primary visual cortex, the selectivity of a neuron in layer 2/3 for stimulus …

Modules of neurons sharing a common property are a basic organizational feature of
mammalian sensory cortex. Primary visual cortex (V1) is characterized by orientation …

IN the mammalian visual cortex, many neurons are driven binocularly and response
properties such as orientation preference or spatial frequency tuning are virtually identical …

NEURONS in the primary visual cortex (VI) respond in well defined ways to stimuli within
their classical receptive field, but these responses can be modified by stimuli overlying the …
