Pdf Feature Selectivity Is Stable In Primary Visual Cortex Across A

Pdf Feature Selectivity Is Stable In Primary Visual Cortex Across A Using 2 photon calcium imaging, we directly compared tuning stability to two stimulus features (orientation and spatial frequency) within the same neurons, specifically in layer 2 3 excitatory. Using 2 photon calcium imaging, we directly compared tuning stability to two stimulus features (orientation and spatial frequency) within the same neurons, specifically in layer 2 3 excitatory.

Pdf Mechanisms Of Feature Selectivity And Invariance In Primary Our results demonstrate that orientation preference is stable across a range of spatial frequencies and that the tuning of distinct stimulus features can be independently maintained within a single neuron. Signals consistent with prediction error have been reported in the mouse visual cortex (v1) when visual flow coupled to running was unexpectedly stopped. here, we show that such signals can be elicited by visual stimuli uncoupled to an animal running. Here, we let 13 monkeys freely view thousands of natural images across 4.6 million fixations, recorded 883 h of neuronal responses in six areas spanning primary visual to anterior inferior temporal cortex and analyzed spatial, temporal and featural selectivity in these responses. Typically, cells in the primary visual cortex are classified as either simple or complex. they both show selectivity for edge orientation but complex cells develop invariance to edge position within the receptive field (spatial phase).

Typically, cells in the primary visual cortex are classified as either simple or complex. they both show selectivity for edge orientation but complex cells develop invariance to edge position within the receptive field (spatial phase). The extent to which stimulus features are stably represented at the level of individual neurons is not well understood. to address this issue, we investigated the persistence of stimulus response tuning over the course of 1 2 weeks in the primary visual cortex of awake, adult mice. Using a data driven model that extracts the spatial structures and nonlinearities associated with neuronal computation, we quantitatively describe the balance between selectivity and invariance in complex cells. Here we hypothesize that the selectivity of v1 neurons to binocular disparity (i.e. the difference is location of images between the two eyes) is derived through convolutional processing, which amplifies correlations present in natural binocular inputs. This feature selectivity is thought to be modifiable by experience at the level of the cortex. here, we demonstrate that selective exposure to a feature during development can alter the population representation of that feature in the primary visual thalamus.
