Figure 1. Representative example of treadmill walking and SNpr LFP activity in lesioned and non-lesioned hemispheres.

Figure 1

A. Rat walking on the treadmill with chronically implanted electrodes. B. Schematic representation of the rat walking ipsiversively and contraversively to the lesion hemisphere (red dot) with the impaired paws (red) outside and inside the treadmill, respectively. C. Wavelet based scalogram of simultaneously recorded SNpr LFP activity from the lesioned hemisphere (top) and the non-lesioned hemisphere (bottom) during one epoch of inattentive rest, treadmill adjustment and treadmill walking. During the treadmill adjustment period, low beta LFP power (12-18 Hz) was reduced in the SNpr in both intact and lesioned hemispheres compared to inattentive rest epochs. Meanwhile, SNpr LFP power increased in the 25-30 Hz range in the lesioned hemisphere. When the rats began to walk, robust 30-35 Hz high beta/low gamma range activity became quite prominent in the SNpr of the lesioned hemisphere (data taken in part from Avila et al., 2010 [31]).
