Olfactory information is sent to all of the following areas except the
a. olfactory cortex
b. limbic system
c. hypothalamus
d. thalamus

The answer is D thalamus

Explanation:

The response to an olfactory stimulus travels through the olfactory nerve, crossing the sieve lamina of the ethmoid, located in the anterior region of the brain. From there the stimulus travels to the olfactory bulb ending in the olfactory glomeruli where aromatic signals are processed, which are conducted by special receptor cells. The information subsequently reaches the hypothalamus and the limbic system. Finally, the information reaches the temporal and frontal cerebral cortex where the odor stimulus becomes conscious.

activation of phospholipase c (plc) indirectly increases intracellular ions through inositol triphosphate (ip3).
