Split Brain
A condition resulting from the surgical division of the cerebrum, leading to two independent hemispheres capable of advanced mental functions.
Corpus Callosum
The nerve tissue that connects the right and left hemispheres of the brain, facilitating communication between them.
Left Hemisphere
The side of the brain typically associated with language, speech, and analytical functions.
Right Hemisphere
The side of the brain often linked to spatial abilities, creativity, and nonverbal tasks.
Visual Field
The entire area that can be seen when the eyes are fixed in one position, divided into left and right halves that project to the opposite hemispheres.
Ipsilateral Input
Sensory information that is processed by the same side of the body and sent to the corresponding hemisphere of the brain.
Anterior Commissure
A bundle of nerve fibers that connects the two hemispheres of the brain, playing a role in interhemispheric communication.
Hippocampal Commissure
A structure that connects the hippocampi of both hemispheres, involved in memory processing.
Bisected-Brain Syndrome
A condition observed in patients who have undergone a corpus callosotomy, leading to distinct behaviors and cognitive functions in each hemisphere.
Cross-Cuing
A phenomenon where one hemisphere can influence the other hemisphere's responses, often observed in split-brain patients.
Visual-Tactile Association
The ability to match visual stimuli with tactile experiences, which can be impaired in split-brain patients.
Language Comprehension
The ability to understand spoken or written language, which is primarily localized in the left hemisphere.
Visual-Constructional Tasks
Tasks that require spatial reasoning and visual-motor coordination, often performed better by the right hemisphere.
Emotional Response
The ability to react emotionally to stimuli, which can occur independently in the right hemisphere even when language capabilities are limited.
Neuroplasticity
The brain's ability to reorganize itself by forming new neural connections, which may be limited in split-brain patients.
Psychophysical Tests
Experimental methods used to assess the psychological and physical responses of split-brain patients to various stimuli.
Two Hemispheres
The concept that the human brain consists of two distinct halves, each capable of independent thought and function when separated.
Visual Input
Information received through the eyes, which is processed by the corresponding hemisphere of the brain based on the visual field.
