Fig. 2From: Cervical trans-spinal direct current stimulation: a modelling-experimental approachCurrent density magnitude distribution in a sagittal slice of the upper thoracic and neck regions for each electrode montage, with the current direction represented by grey arrows of the same length: a) C7-rD, b) C7-CMA; c) C3-T3; d) C4-CMA. Letter “A” marks the active connector position in each electrode. The magnitude colour scale is on the top right and is the same for all montages. The inset on the right of C4-CMA shows the reversal in current density direction inside the spinal canalBack to article page
