(A) Representative LFP averaged from 150 trials during graded forepaw electrical stimulation. (B) Corresponding CSD laminar responses to graded forepaw electrical stimulation. The sink and source current traces were derived from averaged LFP. Zero current base lines were drawn to divide the sink and source currents. The sink current was downward directed and marked with shade. The CSD traces showed apparent sink currents at layers IV and VI.
