High-precision coding in visual cortex
WebAug 1, 1996 · In V1 and V2, with both metrics, temporal precision was highest for contrast (ca. 10-30 ms) and lowest for texture type (ca. 100 ms). This systematic dependence of q on stimulus attribute provides a possible mechanism for the simultaneous representation of multiple stimulus attributes in one spike train. 6.

WebFeb 18, 2000 · Abstract. Theoretical studies suggest that primary visual cortex (area V1) uses a sparse code to efficiently represent natural scenes. This issue was investigated by recording from V1 neurons in awake behaving macaques during both free viewing of natural scenes and conditions simulating natural vision. Stimulation of the nonclassical receptive ... WebDec 16, 2008 · Here we show that the temporal scale of the population code entering visual cortex is on the order of 10 ms and is largely insensitive to changes in visual contrast. ...

WebWe recorded simultaneously from˘20,000 neurons in mouse visual cortex and found that the neural population had discrimination thresholds of 0.3 in an orientation decoding task. … WebAug 1, 1996 · It is shown that the information conveyed by an action potential depends on the duration of the immediately preceding interspike interval (ISI), and the evidence suggests that visual neurons are well equipped to decode stimulus-related information on the basis of relative spike timing and ISI duration. 179 PDF
WebSep 6, 2007 · This remarkable precision at millisecond timescales has been observed in the retina 2,7, the lateral geniculate nucleus (LGN) 5,6 and the visual cortex 1,3,10 as well as in many other sensory ... WebWe recorded simultaneously from up to 50,000 neurons in mouse primary visual cortex (V1) and in higher order visual areas and measured stimulus discrimination thresholds of 0.35° …
WebFeb 8, 2024 · The high precision of bottom-up sensory representations in early visual areas like V1 makes these areas potentially ideal targets for supporting equally precise top-down attentional modulations.
WebApr 14, 2024 · Author summary The hippocampus and adjacent cortical areas have long been considered essential for the formation of associative memories. It has been recently suggested that the hippocampus stores and retrieves memory by generating predictions of ongoing sensory inputs.
