Sentence examples for level of visual cortex from inspiring English sources

In recent years, TMS has been repeatedly used in patients with migraine to test occipital cortex excitability by measuring phosphene threshold (PT), defined as the minimum intensity of a TMS pulse needed to evoke phosphenes: PT is inversely related to the overall level of visual cortex excitability [10], so that a low PT is considered expression of primary visual cortex hyper-excitability.

On the other hand, at a level of visual cortex, severe age-related alterations of RFs and RF properties had been reported [32], [33].

The three-dimensional signal (L + M, L − M, and S channels) in macaque monkeys is not independently treated at the early level of visual cortex.

In this paper we have added an additional, non-trivial, factor in the neuronal organization of LGN responses that must take place at cortical levels, a factor that is probably distributed across several levels of visual cortex.

Based on the positive (rather than negative) correlation between the resting state activity fluctuation in anterior LIM and multiple areas in middle and higher levels of visual cortex, the reversal of the size function in anterior LIM may reflect local processes within the LIM, rather than a direct suppressive input from the visual areas (see above).

Precisely how and at what level(s) of visual cortex this experience-dependent plasticity is implemented remains controversial.

To date, no studies have examined differences in RS between people with autism and neurotypical groups in higher level category-selective regions of visual cortex.

So it remains open whether significantly more training with Ziggerins, resulting in higher levels of automaticity, would result in task-independent engagement of visual cortex by those objects.

The individual degree of orientation discrimination learning was mainly related to the changes in functional connectivity between high-level visual cortex and frontal/central association areas but not within portions of visual cortex.

In the cerebrum, the clusters of visual cortex, sensory-motor cortices, auditory cortex and cerebral nuclei can be clearly observed.

Reliable AOAs were found in regions of visual cortex subserving the far visual periphery.
