The right hemisphere piriform cortex exhibits a distinct pattern of activation in response to a particular scent. Given this, which of the following is true? a) The pattern of activation observed in the right hemisphere piriform cortex corresponds to the pattern of activation across the glomeruli in the left olfactory bulb.   b)The activity in the right hemisphere piriform cortex was not influenced by the quantity of odorant molecules that entered the olfactory epithelium.   c)The odorant molecules that made up the smell were of different shapes and therefore activated different receptors in the right nostril, creating a unique pattern that is conserved first across the olfactory bulb, then along the olfactory tract, then within the thalamus, and then finally in the right hemisphere piriform cortex.   d) The activity in the right hemisphere piriform was initiated by the binding of odorant molecules to G-protein coupled receptors in the right nostril.

Question

The right hemisphere piriform cortex exhibits a distinct pattern of activation in response to a particular scent. Given this, which of the following is true?

a) The pattern of activation observed in the right hemisphere piriform cortex corresponds to the pattern of activation across the glomeruli in the left olfactory bulb.
 
b)The activity in the right hemisphere piriform cortex was not influenced by the quantity of odorant molecules that entered the olfactory epithelium.
 
c)The odorant molecules that made up the smell were of different shapes and therefore activated different receptors in the right nostril, creating a unique pattern that is conserved first across the olfactory bulb, then along the olfactory tract, then within the thalamus, and then finally in the right hemisphere piriform cortex.
 
d) The activity in the right hemisphere piriform was initiated by the binding of odorant molecules to G-protein coupled receptors in the right nostril.
