The hemispheres of the brain control the contralateral sides of the body. So the left side of the brain controls the right side of the body and the right side of the brain controls the left side of the body. A stroke that causes damage to the left side of the brain can cause paralysis on the right side of the body.
What allows for contralateral control?
the arrangement whereby the motor cortex of each cerebral hemisphere is mainly responsible for control of movements of the contralateral (opposite) side of the body.
What does contralateral functioning mean?
Contralateral: Of or pertaining to the other side. The opposite of ipsilateral (the same side). For example, a stroke involving the right side of the brain may cause contralateral paralysis of the left leg.
Who discovered contralateral control?
History of the Theories on Nerve Fiber Midline Crossing. The idea of the contralateral organization of the forebrain, and hence of the crossed nature of motor fibers, was first recognized in the Golden Age of Greece by Hippocrates (460–380 bc).
What is contralateral in psychology?
adj. situated on or affecting the opposite side of the body. For example, motor paralysis occurs on the side of the body contralateral to the side on which a brain lesion is found.
Is somatosensory contralateral?
One can do so because somatosensory information converges in the parietal lobe of the cerebral cortex to provide a cohesive perception of the body and of somatosensory stimuli. Above the level of decussation, the neurons in a somatosensory pathway represent the contralateral (i.e., opposite) side of the body or face.
What is contralateral vision?
Definition. The region of visual space that extends from the vertical meridian (which passes through the center of gaze) peripherally toward the side of the body opposite to the neuron or brain region studied. In general, each side of the brain processes information from the contralateral visual field.
What is contralateral communication?
The processing of information on the opposite side of the body is called contralateral processing (same side = ipsilateral) Tactile information from the left side of the body is transferred to the right side in the spinal cord or brainstem.
What is the contralateral example?
Contralateral: Of or pertaining to the other side. For example, a stroke involving the right side of the brain may cause contralateral paralysis of the left leg.
What does contralateral control mean?
CONTRALATERAL CONTROL: “Contralateral control can be conditioned in some cases so that recovering stroke patients may learn to use parts of their body controlled by the damaged half through use of the other half.”.
What is contralateral control in regards to the brain?
Psychology Definition of CONTRALATERAL CONTROL: the setup wherein the motor cortex of both cerebral hemispheres are primarily accountable for handling of motions of the opposite side of one’s body.
What is contralateral mean?
Medical Definition of contralateral. : occurring on, affecting, or acting in conjunction with a part on the opposite side of the body the motor cortex controls contralateral muscles — compare ipsilateral .
What is a contralateral response?
