Intracortical mechanism of stimulus-timing-dependent plasticity in visual cortical orientation tuning
Visual stimuli are known to induce various changes in the receptive field properties of adult
cortical neurons, but the underlying mechanisms are not well understood. Repetitive pairing …

Stimulus timing-dependent plasticity in cortical processing of orientation
The relative timing of presynaptic and postsynaptic spikes plays a critical role in activity-
induced synaptic modification. Here we examined whether plasticity of orientation selectivity …

Orientation tuning, but not direction selectivity, is invariant to temporal frequency in primary visual cortex
BD Moore IV, HJ Alitto… - Journal of …, 2005 - journals.physiology.org
The activity of neurons in primary visual cortex is influenced by the orientation, contrast, and
temporal frequency of a visual stimulus. This raises the question of how these stimulus …
