Since the brain regions are so specialized in their functioning, damages done to specific areas of the brain can cause specific type of damage. Damage to the left side of the brain can lead to language discrepancies, i.e. difficulty in properly identifying letters, numbers and words, inability to incorporate visual stimuli to comprehend ...
Hyperfixations — on specific activities, interests and, yes, meals — are a common experience among people with ADHD. They may also hyperfocus on a particular topic, Adler says.
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse') is a major component of the brain of humans and other vertebrates.The hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation.
In the brain, where nerve fibers obliquely cross from one lateral side of the brain to the other, that is to say they cross at a level other than their origin. See for examples decussation of pyramids and sensory decussation .
Drugs that boost mood and energy have been known to induce hypergraphia, possibly by increasing activity in brain networks utilizing one of the body's neurotransmitters, dopamine. Dopamine has been known to decrease latent inhibition , which causes a decrease in the ability to habituate to screen out unexpected stimuli.
The fornix (from Latin: fornix, lit. 'arch'; pl.: fornices) is a C-shaped bundle of nerve fibers in the brain that acts as the major output tract of the hippocampus.The fornix also carries some afferent fibers to the hippocampus from structures in the diencephalon and basal forebrain.
In human neuroanatomy, brain asymmetry can refer to at least two quite distinct findings: Neuroanatomical differences between the left and right sides of the brain; Lateralized functional differences: lateralization of brain function; A stereotypical image of brain lateralisation - demonstrated to be false in neuroscientific research.

Lateral brain damage can also affect visual perceptual spatial resolution. People with left hemisphere damage may have impaired perception of high resolution, or detailed, aspects of an image. People with right hemisphere damage may have impaired perception of low resolution, or big picture, aspects of an image.
