Final answer:
Lesions to the frontal lobe can disrupt corollary discharge, which is a neural signal that predicts the sensory consequences of a movement.
Step-by-step explanation:
Lesions to the frontal lobe can result in various changes and impairments, including the disruption of corollary discharge. Corollary discharge is a neural signal that is sent from the motor system to the sensory system in order to predict the sensory consequences of a movement. With a lesion in the frontal lobe, the communication between the motor and sensory systems may be affected, leading to difficulties in predicting and adjusting for the sensory consequences of movements.
