A monkey with an intact MT cortex can detect the direction of moving dots with very low coherence levels (1-2%), indicating high sensitivity to motion. After lesioning the MT cortex, this sensitivity significantly decreases, requiring much higher coherence levels (10-20%) for the monkey to detect motion direction.
