Fig. 3From: Telemetry-controlled simultaneous stimulation-and-recording device (SRD) to study interhemispheric cortical circuits in rat primary somatosensory (SI) cortexA 1-MΩ microelectrode was implanted in SI in the wrist/forearm representation (right hemisphere) and was used to record evoked responses to stimulation of the contralateral wrist/forearm. A total of 10 evoked responses were recorded during peripheral stimulation (100 μA) of the contralateral forelimb on day 21. Inset: Single trace recorded at the same cortical location. Legend axes represent 30 μV and 10 msBack to article page
