How does the size of various parts of the primary somatosensory cortex relate to touch sensitivity and to receptive field size?

A lesion to the medial lemniscus results in what type of sensory loss? Ipsilateral TPV C1 down Contralateral TPV C1 down Ipsilateral loss of pain and temperature C1 down Ipsilateral loss of pain and temperature L1 down Contralateral TPV and CP proprioception at L1   A lesion to the left anterior corticospinal tract at T3 would result in which of the following loss? Ipsilateral unconscious proprioception from T3 down Contralateral unconscious proprioception from T3 down Ipsilateral unconscious proprioception at T3 Ipsilateral unconscious proprioception from L1 down Contralateral unconscious proprioception from L1 down   A lesion of the dorsal root ganglion at L4 would result in which of the following? Ipsilateral loss of all sensation L4 down Ipsilateral loos of all sensation at L4 dermatome Contralateral loss of all sensation at L4 dermatome Contralateral loss of all sensation at L4 down Contralateral loss of touch, pressure, and vibration at L4   A lesion to the lateral…
