← Human Body & HealthIf a patient experiences diminished tactile acuity following a stroke affecting the somatosensory cortex, which adaptation is most likely employed to improve object recognition by touch?
A)Decreased receptor field convergence on neurons
B)Reduced firing thresholds in cortical neurons
C)Downregulation of mechanoreceptor density in fingertips
D)Increased exploratory movements during tactile examination✓
💡 Explanation
Increased exploratory movements enhance tactile perception because active scanning recruits a broader range of mechanoreceptors and provides more spatiotemporal information to the somatosensory cortex. This process, known as haptic exploration, enables more accurate object recognition rather than relying on static touch alone.
