In particular, theta activity increased at the junction of three brain areas: the parietal region, just behind the crown of the head, which perceives sensory information and integrates it into the mysterious state called consciousness; the temporal lobe, behind the temples and responsible for making sense of sound; and the occipital lobe, located at the bottom back of the brain and responsible for processing vision.
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.
We know that the occipital lobe (the portion of the brain that controls vision) is a well - protected structure.
EEG results revealed that threatening images evoked an early increase in theta activity in the occipital lobe (the area in the brain where visual information is processed), followed by a later increase in theta power in the frontal lobe (where higher mental functions such as thinking, decision - making, and planning occur).
Similarly, an area near the junction of the left temporal and occipital lobes was most active when thinking up an action word — and this was immediately next to the motion perception area (Science, vol 270, p 102).
Using magnetic resonance imaging (MRI), they discovered differences in the thickness of parts of the cortex in the temporal and occipital lobes, whose primary roles are in vision and storing knowledge.

Across brain scans taken from 37 subjects, they found that the vertical occipital fasciculus begins in the occipital lobe — the part of the brain's visual processing system located at the back of the head.
Part of the occipital lobe, the circuit has been found to process the perception of color.
We have so far found that both attention and working memory result from the activity of neurons in a network of brain areas that extend from the frontal to the occipital lobe.
The proposed network includes the dorsolateral prefrontal cortex, the inferior and superior parietal lobules, the anterior cingulate gyrus and selected areas within the temporal and occipital lobes.
The cerebrum is divided into a right and a left hemisphere and is composed of pairs of frontal, parietal, temporal, and occipital lobes.

If damage to the occipital lobes does occur, it may lead to an inability to recognize objects.
Of six studies one study [70] observed that a longer duration of manipulation induced more activation in the inferior frontal, temporal, parietal gyrus, occipital lobe, cerebellum or temporal pole and more deactivation in the prefrontal cortex, orbital gyrus or pons than shorter manipulation.
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].
These areas include the occipital lobe, precuneus, posterior cingulate cortex, pre - and post-central gyri, medial frontal gyri and the components of basal ganglia.
In migraine with aura, many researchers now believe, a wave of electrical activity begins — usually at the part of the brain responsible for vision in the occipital lobe, at the back of the head — and then spreads forward over the brain's surface.
As evidenced by brain scanning, different areas of the brain including the occipital lobe are activated by different parts of this simple meditation.
