III.   Biological Systems (PSYBIO)

Theparietal lobes of the COGNO Brain are positioned above the occipital andtemporal lobes and behind the frontal lobes.

The parietal lobes are responsible for integrating sensory information particularly spatial context, symbolic spatial relationships such as mathematics, drawing and body coordinate position and navigation.

The left hemisphere parietal lobe has a greater prominence for those predominantely right handed and supports higher symbolic and spacial functions such as mathematics.

The right hemisphere parietal lobe has a greater prominence for those predominantely left handed and supports higher symbolic and spatial functions such as spatial relationships, plans, drawing and maps.

Damage or malfunction to the parietal lobes have been identified with a number of cognitive performance consequences:

(i) Damage to the left hemisphere is associated with a loss of problem solving, mathematics, reading, writing and understanding symbols; and

(ii) Damage to the right hemipshere is associated with loss of visualization of spacial relationships.
