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 to inputs arriving on the surface of the body and internal receptors
e. Yes, alternating columns contain neurons linked to slowly and rapidly adapting receptors.

b. All of these answers are correct
c. Topographical organization
d. Peripheral information reaches the cortex via the LGN
e. Peripheral receptors depolarize in response to environmental stimuli.

Gene therapy attempts to correct a genetic deficiency by inserting a normal version of the affected gene into the patient's cells. For this to be effective, the cells need to be _______cells that will not passed on to offspring, but they also need to be cells that will keep dividing for the lifetime of the patient. Currently, ______ cells, which produce all the blood and immune cell types of the body, are a preferred target.What limits the use of gene therapy is that it works best on relatively simple conditions caused by the mutation of one single gene. Retroviruses are ________viruses that insert a(n) ________copy of their genome into that of their host cells. After the insertion, the viral genome will be permanently part of the host cell genome.
