Abstract:
Twenty-five years of research support a shift from viewing the Extrastriate Body Area (EBA) as a purely visual module to recognizing it as a dynamic hub integrating multisensory, motor, and social signals. Inspired by the review of de Gelder and colleagues, we highlight findings that the EBA operates within distributed networks, contributes to emotion and social perception, and encodes predictive representations of body states. Developmental findings, neuromodulatory influences, and evidence from clinical conditions extend its scope. Emerging evidence of EBA involvement in interoceptive and olfactory processing underscores embodied, affect-laden role, motivating reconceptualization as a core integrative key node.

Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
Sensory Perception: Organization of the Somatosensory System
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the stimulus...
