Abstract:
Interoception is the sensing and representation of signals from the internal organs and involves a bidirectional communication between the brain and the body. Interoception also supports allostasis, which is the process by which the brain anticipates the needs of the body and preemptively initiate responses to meet internal or external demands. The coordination between these 2 processes is orchestrated by a distributed allostatic-interoceptive brain network. Impaired interoceptive accuracy, allostatic overload, and central sensitization contribute to the manifestations of neurodegenerative disorders and chronic functional neurologic symptoms.

Functional Brain Systems: Reticular Formation
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...
