The Halstead–Reitan Neuropsychological Test Battery (HRNB) and allied procedures is a comprehensive suite of neuropsychological tests used to assess the condition and functioning of the brain, including etiology, type (diffuse vs. specific), localization and lateralization of brain injury.
The concept of "right-brained" or "left-brained" individuals is considered a widespread myth which oversimplifies the true nature of the brain's cerebral hemispheres (for a recent counter position, though, see below). Proof leading to the "mythbuster" of the left-/right-brained concept is increasing as more and more studies are brought to light.
The Bergen Left–Right Discrimination (BLRD) test is designed to measure individual performance in LRD accuracy. However, this test has been criticized for incorporating tasks that require the use of additional strategies, such as mental rotation (MR). [10]
In popular psychology, the illusion has been incorrectly [6] identified as a personality test that supposedly reveals which hemisphere of the brain is dominant in the observer. Under this wrong interpretation, it has been popularly called the "right brain–left brain test", [7] and was widely circulated on the Internet during late 2007 to ...
Rightward asymmetry can be seen in the right central sulcus (potentially suggesting increased connectivity between motor and somatosensory cortices in the left side of the brain), lateral ventricle, entorhinal cortex, amygdala and temporo-parieto-occipital area. Sex-dependent brain asymmetries are also common. For example, human male brains are ...
If the right carotid is injected, the right side of the brain is inhibited and cannot communicate with the left side. The effect shuts down any language and/or memory function in that hemisphere in order to evaluate the other hemisphere. An EEG recording at the same time confirms that the injected side of the brain is inactive as a neurologist ...
These fish demonstrate an individual eye preference when examining their reflection in a mirror. Fish which show a right-eye preference in the mirror test prefer to be on the left side of the school. Conversely, fish that show a left-eye preference in the mirror test or were non-lateralised, prefer to be slightly to the right side of the school.
For example, a stroke affecting the right parietal lobe of the brain can lead to neglect for the left side of the visual field, causing a patient with neglect to behave as if the left side of sensory space is nonexistent (although they can still turn left). In an extreme case, a patient with neglect might fail to eat the food on the left half ...
