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 ...
Contralateral (from Latin contra 'against'): on the side opposite to another structure. [24] For example, the right arm and leg are controlled by the left, contralateral, side of the brain. Ipsilateral (from Latin ipse 'same'): on the same side as another structure. [25] For example, the left arm is ipsilateral to the left leg.
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 numerous other factors which contribute in complex ways to physical hand preference.
The best example of an established lateralization is that of Broca's and Wernicke's areas, where both are often found exclusively on the left hemisphere. Function lateralization, such as semantics , intonation , accentuation , and prosody , has since been called into question and largely been found to have a neuronal basis in both hemispheres ...
The greater part of the ascending axons forming the lateral lemniscus will terminate in the ipsilateral CNIC however a few follow the commissure of Probst and terminate on the contralateral CNIC. The axons of most of the CNIC cells form the brachium of IC and leave the brainstem to travel to the ipsilateral thalamus. Cells in different parts of ...

"In reality," he said, "foodborne illnesses can lead to severe and long-lasting health issues, hospitalization or even death, especially for vulnerable populations like the immunocompromised ...
A gyrus is an outward folding of the brain, for example the precentral gyrus. A sulcus is an inward fold, or valley in the brain's surface - for example the central sulcus. Additional terms used to describe these may include: Annectent gyrus, for a small gyrus hidden in the depth of a sulcus; sulcal fundus, for the bottom of a sulcus, an inward ...
