10. A large territory of the primary somatosensory cortex (S1) in rodents is responsive to vibrissa (whisker) deflection. Within S1, inputs from each vibrissa are organized into anatomically distinguishable clusters of neurons called barrels. One barrel represents one vibrissa.

  1. How experimentally might we reduce the size of a cortical barrel in S1?
  2. How might we increase the size of a cortical barrel?

Does the somatosensory cortex have a columnar organization similar to the visual cortex? a. Yes, alternating columns contain neurons responding to pleasant and aversive stimuli b. No, columnar organization doesn’t make sense in the somatosensory system because the receptor types are too diverse to dedicate a full column to each sensory attribute. c. No, the body is already represented several times in the somatosensory cortex, with different modalities assigned to different brain regions d. Yes, alternating columns contain neurons responding...
