The existence of auditory responses in the occipital cortex of cataract - recovery patients, as observed in the study, therefore poses crucial questions regarding how these non-visual inputs coexist or even interfere with visual functions.

As a number of neuroimaging studies show, the early onset of permanent blindness alters the response of the neurons of the visual cortex and causes a cortical compensatory re-organization in the occipital lobe.

In contrast, visual information taken in by the eyes tends to flow from the occipital lobe — which makes up much of the brain's visual cortex — «up» to the parietal lobe.

This hypothesis is supported by EEG and functional MRI scans, which revealed in previous studies that just before insight takes place, the occipital cortex, which is responsible for visual processing, momentarily shuts down, or «blinks,» so that ideas can «bubble into consciousness,» Kounios says.

The primary visual cortex is Brodmann area 17, located in the interior portion of the occipital lobe at the calcarine sulcus and sometimes continuing onto the surface of the lobe.

Rafique and colleagues (2016) examined the effectiveness of multi-day rTMS to the occipital cortex in a patient with continuous visual phosphene hallucinations for more than 2 years following occipital stroke.

They presented a case of multi-day application of rTMS to visual cortex and demonstrated that rTMS provided a valuable therapeutic intervention in modulating visual hallucinations following occipital damage.

Moreover, the secondary cortices of the occipital lobe exhibited high SI values (Figure 2), which is comparable to the reduced variability observed in visual components found by a previous ICA study [5].

However, age differences were identified in more posterior visual regions, including lateral occipital cortex, where older adults showed similar ERS for both retrieval targets and lures.

Cortical activation for individuals with migraine was specifically suppressed in visual area V2 of the brain's occipital cortex with the POTs, and this cortical activation suppression was extended to other visual areas as well.
