Figure 1.
LFP oscillations recorded in the DLS are modulated by the execution of a stereotyped motor sequence. A, Illustration of the front-rear-front running sequence performed by rats on a motorized treadmill (left) and the trajectory of an animal during a single trial (right). B, Run and baseline are 5-s-long epochs chosen during trials and intertrials, respectively. C, Schematic representation of electrodes position. D, Raw LFP traces recorded with a four-shank silicon probe (a single channel per shank is shown). E, Time-frequency power spectrogram during consecutive trials and intertrials. F, Striatal LFP power spectra during run and baseline epochs (mean ± SD, average over electrodes and sessions). Power was normalized by 1/frequency2. Shaded red area indicates the frequencies at which the power is significantly different in run compared to baseline.
