Expanded definition
The concha is the bowl-shaped region leading toward the ear canal. The crus of the helix divides it into the upper cymba conchae and the lower cavum conchae.
The cymba conchae is widely discussed as an active location in taVNS research because anatomical and neuroimaging work has linked selected conchal regions to auricular vagal pathways.
Anatomical location is only one protocol variable. Electrode geometry, contact area, waveform, intensity, side, control condition, and outcome measure all influence interpretation.
What the term does not establish
Why the distinction matters
The term is common in taVNS papers, so a precise anatomical definition helps readers compare protocols rather than treating “ear stimulation” as one method.
