Now that the location and function of olfactory receptors have been introduced, olfactory receptor neurons will be covered in greater detail. Olfactory receptor neurons are bipolar cells that are found within the olfactory epithelia of the nasal cavity. Apically, dendrites, also called olfactory cilia...
Olfactory Bulb | Structures, Function & Location from Chapter 11 / Lesson 1 67K Explore the inner workings of olfaction with detailed explanations of the olfactory bulb. Learn about its physiological function and its adjacent structures. Related...
The Primary Olfactory Cortex refers to brain regions one synapse away from the olfactory bulb, including the piriform cortex, anterior cortical nucleus of the amygdala, and entorhinal cortex. It receives inputs from the olfactory bulb and plays a crucial role in processing olfactory information. ...
Postnatal neurogenesis provides an opportunity to understand how newborn neurons integrate into circuits to restore function. Newborn olfactory sensory neurons (OSNs) wire into highly organized olfactory bulb (OB) circuits throughout life, enabling lifelong plasticity and regeneration. Immature OSNs form...
The olfactory tract, after entering the brain, is divided into two main pathways; 1) the Primitive pathway and 2) the Less old pathway. Both these pathways bypass the thalamus and directly enter the brain cortex. Primitive Pathway Leading to the Medial Olfactory Area ...
These included: congestion of the nasal mucosa due to swelling and obstruction of the olfactory cleft; infection and death of olfactory receptor neurons; viral neuroinvasion along the olfactory nerve; infection and death of neurons in the olfactory bulb and cortex; altered neuronal function due to ...
Therefore, we aimed to demonstrate that the OWMC paradigm is more sensitive and consistent in the early detection of declines in cognitive function than other commonly used behavioral paradigms. The prefrontal cortex (PFC), retrosplenial cortex (RSC), subiculum (SUB), and amygdala (AMY) of 5X...

Studies are underway to examine the degree of inflammation in the piriform cortex, to which the olfactory tracts project. One shortcoming of our study is that no objective assessment of olfactory function had been performed in any of the participants that subsequently died within the hospital, in ...
Neural stem cells Olfactory cortex Thalamus Introduction The mammalian amygdalar pallial complex consists of a heterogeneous group of nuclei located in the telencephalic temporal pole, rostrally to the caudo ventral hippocampus. They are implicated in reward evaluation of stimuli and emotional learning ...
