What is contralateral control?

Abstract. Contralateral control, the arrangement whereby most of the human motor and sensory fibres cross the midline in order to provide control for contralateral portions of the body, presents a puzzle from an evolutionary perspective.

What is contralateral brain function?

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 is contralateral hemisphere?

the cerebral hemisphere on the opposite side of the body from any organ or part that is being considered as the reference point.

Is the brain contralateral or ipsilateral?

For decades, scientists have been finding evidence in both animals and humans to suggest that it’s not just the contralateral (opposing side) brain hemisphere that plays a role in body movement, but also the ipsilateral (same side) hemisphere.

What does contralateral control mean quizlet?

What is meant by contralateral control/input? Right half of the brain controls left half of the body, while left half of the brain controls right half of the body.

What does contralateral mean in psychology?

What does contralateral mean psychology?

the opposite side of the
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.

What is difference between ipsilateral and contralateral?

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.

What does it mean to say that the brain relies on contralateral connections?

It is usually used in regards to the opposite side of the body from which something occurs. 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.

Which of Hippocrates observations indicates early evidence of contralateral motor Organisation in the human brain?

Which of Hippocrates’ observations indicates early evidence of contralateral motor organisation in the human brain? If an incision is made in the left temple, spasm seizes the riht side of the body, and if the incision is made in the right temple, spasm seizes the left side of the body. You just studied 19 terms!

What is the contralateral example?

What is an example of contralateral?

Contralateral. Contralateral is a term that references the opposite side of something. ‘Contra’ means opposite or contrasting while ‘lateral’ means side. It is usually used in regards to the opposite side of the body from which something occurs. The hemispheres of the brain control the contralateral sides of the body.

What is the contralateral organization of the brain?

The contralateral organization involves both executive and sensory functions (e.g., a left-sided brain lesion may cause a right-sided hemiplegia ). The contralateral organization is present in all vertebrates but in no invertebrate.

What is an example of a contralateral hemisphere?

Another example is that each hemisphere in the brain tends to represent one side of the body. In the cerebellum, this is the same body side, but in the forebrain this is predominantly the contralateral side .

What is meant by concentral control?

CONTRALATERAL CONTROL. Nugent, Pam M.S. 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.
