What is the Rhinencephalon composed of?
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.
What is Rhinencephalon?
Definition of rhinencephalon : the chiefly olfactory part of the forebrain.
Where is the Rhinencephalon?
The specialized chemoreceptor of the olfactory rhinencephalon is a bipolar neuron located in the olfactory epithelium of the nasal mucosa that lies in the caudal part of the nasal cavity. This is primarily the nasal mucosa that covers the ethmoid labyrinth.
What is olfactory cortex?
The olfactory cortex is the part of the cerebral cortex that processes olfactory information. It is involved in the sense of smell.
What contains the olfactory cortex?
The Olfactory Cortex. The primary olfactory cortex has been defined as cortical brain regions which receive the mitral and tufted cell axon projections. This includes the anterior olfactory nucleus, the pyriform cortex, regions of the amygdala and periamygdaloid complex, and the rostral entorhinal cortex (Fig. 3).
What is the fornix made of?
The fornix is a prominent bundle of white matter fibers seen on the medial aspects of the cerebral hemispheres. It begins in the hippocampus as the alveus, which is a collection of myelinated fibers found medially to the floor of the temporal horn of the lateral ventricle.
How does a fornix work?
Fornix is the main output tract of the hippocampus. Its main function is to transmit the information from the hippocampus to the mammillary bodies and the anterior nucleus of thalamus. The commissure of the fornix also serves to connect the two hippocampal formations.
What is the olfactory bulb connected to?
amygdala
The main olfactory bulb connects to the amygdala via the piriform cortex of the primary olfactory cortex and directly projects from the main olfactory bulb to specific amygdala areas. The accessory olfactory bulb resides on the dorsal-posterior region of the main olfactory bulb and forms a parallel pathway.
