Neural networks and the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation in depression

Review article on the potential of transcutaneous auricular vagus nerve stimulation (taVNS) in managing depression — and as it possibly relates to pain and other chronic conditions affected by negative emotional affect and psychological conditions such as depression.   Reference: Liu, CH., Yang, MH., Zhang, GZ. et al.

Tragus or cymba conchae? Investigating the anatomical foundation of transcutaneous auricular vagus nerve stimulation (taVNS). Citation: (Badran, 2018)

Badran et. al. provide commentary on the growing interest in modulating the auricular branch of the vagus nerve (ABVN). Researchers clearly want to know which ear target is optimal for taVNS e tragus or cymba conchae. Although the authors note discrepancies — identified by Burger and Verkuil in the investigation of a manuscript by Peuker and Filler describing vagus innervation of the ear — that they have found difficult to resolve, their commentary offers insights.[1] First, recognizing the i...


Neurophysiologic effects of transcutaneous auricular vagus nerve stimulation (taVNS) via electrical stimulation of the tragus: A concurrent taVNS/fMRI study and review. Citation: (Badran 2017)

Since prior studies of transcutaneous auricular vagus nerve stimulation (taVNS) with functional magnetic resonance imaging (fMRI) have had inconsistent findings (owing to variability in stimulation targets and parameters), the authors undertook to develop a transcutaneous auricular vagus nerve stimulation (taVNS)/functional magnetic resonance imaging (fMRI) system enabling the comparison of taVNS in relation to control stimulation through concurrent electrical stimulation and fMRI acquisit...
