Damage to either the right or left hemisphere, and its resulting deficits provide insight into the function of the damaged area. There is truth to the idea that some brain functions reside more on one side of the brain than the other. We know this in part from what is lost when a stroke affects a particular part of the brain.
Contralateral brain. The contralateral organization of the forebrain (Latin: contra‚ against; latus‚ side; lateral‚ sided) is the property that the hemispheres of the cerebrum and the thalamus represent mainly the contralateral side of the body. Consequently, the left side of the forebrain mostly represents the right side of the body, and ...
The human brain's control of motor function is a mirror image in terms of connectivity; the left hemisphere controls the right hand and vice versa. This theoretically means that the hemisphere contralateral to the dominant hand tends to be more dominant than the ipsilateral hemisphere, however this is not always the case [ 2 ] and there are ...
The reasons for this are not fully understood, but it is thought that because the left cerebral hemisphere of the brain controls the right side of the body, the right side is generally stronger; it is suggested that the left cerebral hemisphere is dominant over the right in most humans because in 90–92% of all humans, the left hemisphere is ...
Similarly, motor control signals sent out to the body also come from the hemisphere on the opposite side. Thus, hand preference (which hand someone prefers to use) is also related to hemisphere lateralization. [citation needed] In some aspects, the hemispheres are asymmetrical; the right side is slightly bigger.
The brain controls most of the activities of the body, ... Thus, the right side of the brain receives somatosensory input from the left side of the body, and visual ...
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.
The cerebrum is a major part of the brain, controlling emotions, hearing, vision, personality and much more. It controls all precision of voluntary actions, and it functions as the center of sensory perception, memory, thoughts and judgement; the cerebrum also functions as the center of voluntary motor activities.
