We pointed out earlier that the olfactory sense bypasses the thalamus, the main sensory relay station of the brain. However, some studies have pointed out a newer pathway that is present in some higher animals according to evolutionary history. This pathway does not bypass the thalamus like the ...
In this case, the olfactory nerve is responsible for our sense of smell. The odor information originates in the epithelium of the nasal cavity and is transported to the brain via components of the olfactory nerve (cranial nerve 1 - CNI) and the olfactory pathway. A decreased sense of ...
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 ...
Other conditions that affect your olfactory nerve include: Multiple sclerosis Obesity Diabetes Hypertension Malnutrition Problems with nerves in your brain can be severe. It's best to talk to your doctor as soon as possible if you notice problems with your senses. You should act fast, whether it...

1d). In contrast, the extent to which individual glomeruli are innervated by immature OSN axons varies, and the density of immature OSN axons may be higher proximal to the olfactory nerve layer and around the periphery of the glomerulus4,44. This was also evident for immature OSNs expressing...
Electrical stimulation of the olfactory nerve in an in vitro whole-brain preparation elicited synaptic responses in reticulospinal cells that were modulated by DA. Local injection of DA agonists in the medOB decreased the reticulospinal cell responses whereas the D2 receptor antagonist raclopride ...

In addition, in rainbow trout, magneto-receptor cells are present in the lamina propria of the olfactory epithelium, which is linked to the brain through the superficial ophthalmic branch of the trigeminal nerve. The cells contain magnetite crystals and respond to changes in the intensity of an ...
