Figure 4: The electrophysiological experiment configuration and results in vivo.

From: Enhanced Flexible Tubular Microelectrode with Conducting Polymer for Multi-Functional Implantable Tissue-Machine Interface

Figure 4

(a,b) Illustrative and actual configuration of the electrophysiological experiment, respectively. (c) X-ray image of the rat hind leg, in which the yellow dash line indicated the location of implanted tubular microelectrodes in gastrocnemius (GA) and tibialis anterior (TA). (d) EMG signals recorded by PEDOT/PSS modified electrode in GA (CH1), bare gold electrode in GA (CH2), PEDOT/PSS modified electrode in TA (CH3) and bare gold electrode in TA (CH4). The waveforms on the left and right referred to the EMG signal recording before and after lidocaine injection, respectively. (e,f) Frequency spectrum analysis of EMG signals before and after lidocaine injection, respectively.
