striatum; it receives input from the frontal lobes and also from the limbic system (below). At its base is the
nucleus accumbens (NA).
[edit] Olfactory bulb projections
Olfactory sensory neurons project axons to the brain within the olfactory nerve, (cranial nerve I).
The Olfactory Bulb."In many of the lower animals this contains a cavity which communicates through the olfactory tract with the lateral ventricle.
The axons from all the thousands of cells expressing the same odor receptor converge in the olfactory bulb.
A tuft of capillaries projecting into a renal corpuscle in a kidney. Also, a small spongy mass of tissue in the proboscis of hemichordates, presumed to have an excretory function. Also, a concentration of nerve fibers situated in the olfactory bulb.
large so there are still smaller windows of opportunity to block segments of patterning of the forebrain. Holoprosencephaly is really a spectrum of malformations that can exist in very mild forms where, for example, only the olfactory bulb is missing.
