The cerebral cortex receives multiple afferents from the thalamus that segregate by stimulus modality forming cortical maps for each sense. In vision, the primary visual cortex maps the multiple ...

Moreover, even when presented with a task under new, unlearned conditions (for example, when the stimulus learned is in a new location), the examinees who learned the memory flash method performed ...

This useful study shows that stimuli of a certain size elicit theta oscillations in V1 neurons both in spikes and local field potentials, and monkeys performing a dot detection task on these stimuli ...

For example, if presented with a sound followed by a visual milliseconds apart and perceived as asynchronous, one is much more likely to report the next audio-visual stimulus pair as synchronous ...

Glaucoma patients show slower visual response times, indicating impaired visual signal processing rather than motor or attention deficits. The study involved glaucoma patients and healthy controls ...

V1 neurons normally show sensitivity to different features of a visual stimulus, such as color or direction of movement. The preprocessed data is transmitted to subsequent areas of the visual cortex.

They found that not only did the neurons activated by the visual stimulus keep more active during subsequent sleep, sleep is vital to their ability to connect the fear memory to the sensory event.

However, rigorous testing of this model requires sampling a larger stimulus space than previously possible. We used stable GCaMP6f expression and two-photon calcium imaging to probe a very large ...

Second, we describe a less studied, but no less interesting form of plasticity in the visual cortex known as stimulus-selective response potentiation (SRP). SRP results in increases in the response of ...

Traumatic brain injury (TBI) can lead to long-term visual impairment (like loss of visual acuity). For example, estimates suggest that as many as 75% of current or former soldiers live with ...
