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 ...
An example of this is when a person steps on a nail: The leg that is stepping on the nail pulls away, while the other leg takes the weight of the whole body. [4] The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus.
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.
For example, in a gap detection test, subjects with egocentric hemispatial neglect on the right side often make errors on the far right side of the page, as they are neglecting the space in their right visual field. [21] The next range of neglect is "allocentric" neglect, where individuals neglect either their peri-personal or extrapersonal space.
Hands/ feet coordination involves the coordination of the upper limbs and the lower limbs, including the ipsilateral side of the body (e.g. left hand and left foot), or the contralateral side (both sides of the limbs). Examples include walking and climbing.
In a review, it was associated to the "impulsive behaviour", handedness, mostly left and/or crossed lateralities, and above of all, the eyedness or eye-laterality as a key to detect and to relate brain lateralization which that behavioural disorder when it is crossed-eye-hand laterality [23] which has also been related in a work, reporting a ...

Each hemisphere's V1 receives information directly from its ipsilateral lateral geniculate nucleus that receives signals from the contralateral visual hemifield. Neurons in the visual cortex fire action potentials when visual stimuli appear within their receptive field. By definition, the receptive field is the region within the entire visual ...
