Specific neural mechanisms underlie the ASMR physical sensation.
Neuroimaging and electrophysiological studies consistently show that specific neural signatures—including activation in reward and emotional processing regions, altered network connectivity, and unique cortical structures—underlie the ASMR physical sensation.
The retrieved papers provide robust functional MRI, structural MRI, and EEG evidence identifying specific brain regions, network dynamics, and structural cortical differences associated with the ASMR experience. Therefore, the claim that specific neural mechanisms underlie the ASMR physical sensation is well supported.

Demonstrates via fMRI that ASMR experiences correlate with specific brain activations in reward and emotional arousal regions like the NAcc, dACC, and insula.
