Critical Brain Regions Involved in Olfactory Network. Scheme of the olfactory system detailing the process of olfaction. Olfactory sensory neurons transduce odor information through electrical signals, initiating neurotransmitter release in the olfactory bulb. Regions implicated in early olfactory processing encompass the olfactory bulb and tract, the piriform cortex, amygdala, entorhinal cortex, and hippocampus. Image created using Biorender
