[Is there a correlation between motor neglect and unilateral sensory neglect].
Similarities between motor neglect and unilateral sensorial neglect are so striking that their mechanisms are likely to be almost the same. As the attentional interpretation is no longer possible for motor neglect, and the intentional interpretation may be dismissed in man because of the loss of automatic movements, the psychological interpretation must be abandoned. A purely physiological hypothesis is put forward for motor neglect. When applied to unilateral neglect, it suggests that sensorial signals treated by the right hemisphere do not reach a significant functional level. In such case, the left hemisphere assumed to be dominant for awareness of body and space would receive from the right hemisphere a message interpreted as nul and would neglect information coming from the left.
