Studies have found that individuals with schizophrenia have a lack in brain asymmetry thus reducing the functional efficiency of affected regions such as the frontal lobe. [21] Conditions include leftward functional hemispheric lateralization, loss of laterality for language comprehension, a reduction in gyrification, brain torsion etc. [22] [23]
MRI studies have found a smaller brain volume and larger ventricles in people with schizophrenia – however researchers do not know if the shrinkage is from the schizophrenia or from the medication. [ 143 ] [ 144 ] The hippocampus and thalamus have been shown to be reduced in volume; and the volume of the globus pallidus is increased.
In rodents, the hippocampus is positioned so that, roughly, one end is near the top of the head (the dorsal or septal end) and one end near the bottom of the head (the ventral or temporal end). As shown in the figure, the structure itself is curved and subfields or regions are defined along the curve, from CA4 through CA1 (only CA3 and CA1 are ...
The body behind the head compensates the asymmetric body orientation in the opposite direction, by turning to the right. (See schema.) Due to these oppositely directed compensations of the anterior head and the rest of the body, the animal becomes twisted. [10] The optic tract grows from the retina to the optic tectum.
The parietal lobe is located directly behind the central sulcus, superior to the occipital lobe and posterior to the frontal lobe, visually at the top of the back of the head. [18] The make up of the parietal lobe is defined by four anatomical boundaries in the brain, providing a division of all the four lobes. [18]

Although the brain area was thought to be unique to humans, almost like the anatomic version of the linguistic "language organ" of Noam Chomsky, it was shown to be similarly leftward asymmetric in chimpanzees and other great apes but not other primates, [15] as was a related, rightward asymmetric, brain region the planum parietale that is ...
These claims are often inaccurate, as most brain functions are actually distributed across both hemispheres. Most scientific evidence for asymmetry relates to low-level perceptual functions rather than the higher-level functions popularly discussed (e.g. subconscious processing of grammar, not "logical thinking" in general).
