Signals from odor sensation are sent from the olfactory bulb through mitral and tufts cell axons via the lateral olfactory tract and synapse at the primary olfactory cortex.
12.
:The olfactory receptor neurons connect to the olfactory nerve which connects to the olfactory bulb which connects to other parts of the brain via the olfactory tract-see olfactory system.
13.
As such, the rhinencephalon includes the olfactory bulb, the olfactory tract, the olfactory tubercle and striae, the anterior olfactory nucleus and parts of the amygdala and the piriform cortex.
14.
Here the fascicles enter the olfactory bulb and synapse there; from the bulbs ( one on each side ) the olfactory information is transmitted into the brain via the olfactory tract.
15.
It serves in this way to connect the two temporal lobes, but it also contains decussating fibers from the olfactory tracts, and is a part of the neospinothalamic tract for pain.
16.
It has been postulated that the neurons forming the nucleus of the lateral olfactory tract derive from the dorsal pallium and migrate tangentially into its final position caudal to the olfactory tuberculum.
17.
The brain was globular and similar in shape to that of birds and troodontid theropods, the cerebrum was expanded in a way similar to most theropods, and the olfactory tracts were relatively large.
18.
These stimulants are transduced into electrical activity in the olfactory neurons, which then transmit these impulses to the olfactory bulb and from there to the rest of the central nervous system via the olfactory tract.
19.
From the olfactory bulb, mitral / tufted cells send axons via the lateral olfactory tract ( the cranial nerve I ) to the olfactory cortex, which includes the piriform cortex, entorhinal cortex, and parts of the amygdala.
20.
The mitral cells leave the olfactory bulb in the lateral olfactory tract, which synapses on five major regions of the cerebrum : the anterior olfactory nucleus, the olfactory tubercle, the amygdala, the piriform cortex, and the entorhinal cortex.
