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.
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. [1]
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.
Special interests are sometimes confused with hyperfixations. [11] Hyperfixations are short-lived periods of strong interest in a subject over a few days to months which can occur in anyone (although are especially common in people with ADHD ), [ 12 ] while special interests are an autistic trait and usually last years.

The uncinate fasciculus is a white matter association tract in the human brain that connects parts of the limbic system such as the temporal pole, anterior parahippocampus, and amygdala in the temporal lobe with inferior portions of the frontal lobe such as the orbitofrontal cortex.
The pain you’re feeling when you get brain freeze is actually from a layer of receptor cells in the outer covering of the brain, called the meninges. This is where the internal carotid artery ...
The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral cortex, that is supported by an inner layer of white matter. In eutherian (placental) mammals, the hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers.
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.
