In split-brain patients, the corpus callosum is cut, severing the main structure for communication between the two hemispheres. The first modern split-brain patient was a war veteran known as Patient W.J., [10] whose case contributed to further understanding of asymmetry. Brain asymmetry is not unique to humans.
What's The Saying is a fun and challenging game that will put your brain to work. The object of the game is to match a common phrase with an accompanying coded image. These will test even the most ...
The left cerebral hemisphere of the brain. The left-brain interpreter is a neuropsychological concept developed by the psychologist Michael S. Gazzaniga and the neuroscientist Joseph E. LeDoux . [ 1 ] [ 2 ] It refers to the construction of explanations by the left brain hemisphere in order to make sense of the world by reconciling new ...
Although both sides of the hemisphere has different responsibilities and tasks, they both complete each other and create a bigger picture. [21] 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.
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 performs a neurological examination. The neurologist engages the patient in a series of language and memory related tests.
a) The right hemisphere has more control over emotion than left hemisphere. [n 2] b) The right hemisphere is dominant in emotional expression in a similar way that the left hemisphere is dominant in language. c) The right hemisphere is dominant in the perception of facial expression, body posture, and prosody.
Broad generalizations are often made in popular psychology about certain functions (e.g. logic, creativity) being lateralized, that is, located in the right or left side of the brain. These claims are often inaccurate, as most brain functions are actually distributed across both hemispheres.
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.
