contralesional

Often patients will neglect features present on the contralesional side of space and objects.

However, when presented on its own, patients can correctly perceive the contralesional stimulus.

For all display types detection of single contralesional targets was close to 100% correct.

It is especially true with their contralesional hand.

This shows that the failure to describe things in the contralesional side can also affect verbal items.

If the patient is asked to draw a complex picture they may neglect the entire contralesional side of the picture.

A patient with motor neglect does not use a contralesional limb despite the neuromuscular ability to do so.

However, this does not account for the ability of extinction patients being able to correctly identify contralesional stimuli in isolation.

Under simultaneous presentation, the contralesional stimulus is apparently ignored by the patient, or extinguished.

In this theory neglect patients demonstrate a failure to describe the contralesional side of a familiar scene, from a given point, from memory.

If asked to draw an individual object, the patient will not draw the contralesional side of that object.

Patients show a contralesional loss of space representation with a deviation of spatial reference to the ipsilesional side.

In cases of somatoparaphrenia, which may be caused by personal neglect, patients deny ownership of contralesional limbs.

The contralesional tactile detection is hampered by sounds in tactile extinction patients.

Rehabilitation of unilateral neglect: Reducing inhibitory competition by contralesional limb activation.

Analogous to neglect, extinction affects the contralesional visuospatial field in majority of patients with unilateral damage.

When presented with simultaneous stimuli, the patient will ignore the contralesional stimuli, and only report the ipsilesional.

Specifically, patients with motor neglect have relatively normal movement when encouraged to use the contralesional limb, but do not perform the same movement spontaneously.

Trained professions can help to improve communication and are primarily advised to direct attention to the contralesional [affected] side of the body.

This suggests a deficit in the ability to use attention to improve performance in detection and processing of visual targets in the contralesional region.

Neglect patients may also ignore the contralesional side of their body; for instance, they might shave or apply make-up only to the non-neglected side.

Unilateral lesions of various brain structures can cause a failure to sense contralesional stimuli in the absence of obvious sensory losses.

This extinction is also caused by brain damage on one side of the brain where awareness is lost on the contralesional side.

The neglect of input, or "inattention," includes ignoring contralesional sights, sounds, smells, or tactile stimuli.

Neglect may affect awareness for contralesional inputs in other sensory modalities as well (e.g. audition, touch), but most research has focused on the visual deficits.
