The olfactory tract is split into medial and lateral.
Their projections are to 5 different areas of the brain- anterior olfactory nucleus, olfactory tubercle, Piriform cortex, Amygdala, Entorhinal cortex
The lateral tract originates from the olfactory epithelium separates into mitral cells and tuft cells. mitral cells synapses onto all 5 of the regions to ultimately synapse onto the orbitofrontal cortex via the thalamus or the frontal cortex. tufted cells on the other hand only synapse onto the anterior olfactory nucleus and the olfactory tubercle
The medial or vomeronasal tract projects to mitral cells that synapse only to the Amygdala

What are the function of the nerve fibers?
Arevbranching fibers at the end of the axon that lead the nervous impulse from the axon to the synapse
Where do the nostrils lead?
A Perch's nostrils lead to a sac like area where the olfactory sensors pick up odors.
What happens if the sensory nerve is cut?
Cutting the optic nerve would lead to loss of vision in the affected eye.Damage to either optic tract would lead to loss of HALF the vision in in either eye (due to the crossing over of tracts in the optic chiasm). so you would loose half the visual field in either eye. (neoroscience student).
Can ulnar nerve compression lead to ALS?
No
Can a lack of Vitamin B12 lead to Alzheimer's disease?
No. It can lead to nerve trouble but that is not alzheimers.
Why lead products import banned in India?
Lead is devastating to the human body, inhibiting oxygen and calcium transport and altering nerve transmission in the brain. Most lead poisoning occurs when people swallow lead paint chips or breathe in lead dust. The lead builds up in soft tissue -- kidneys, bone marrow, liver, and brain -- as well as bones and teeth. Lead absorption rates vary; the gastrointestinal tracts of adults typically absorb 10-15 percent of ingested lead, while those of pregnant women and children can absorb up to 50 percent.
Which nerve disease can lead to extreme facial pain?
Trigeminal neuralgia is the nerve disease that causes extreme facial pain.
Why do collagen problems lead to bone problems?
collagen fibers are part of the bone tissue
What conducts impulses from the AV node to branches which lead to the Purkinje fibers?

How do pressure waves in the cochlea lead to an action potential in the auditory nerve?

Which part of the brain does the optic nerve lead to?
Lateral Genicluate Nucleus
What causes nerve pains and how to cure it?
Sciatica is pain, tingling, or numbness produced by an irritation of the nerve roots that lead to the sciatic nerve. The sciatic nerve is formed by the nerve roots coming out of the spinal cord into the lower back. It goes down through the buttock, then its branches extend down the back of the leg to the ankle and foot.
