Activity of a pyramidal tract projecting cell (PTN) of the motor cortex during walking on the flat surface and horizontal ladder with crosspieces 5 cm wide.  Latent period of cell’s response to stimulation of the pyramidal tract was 1.1 ms; collision test was satisfied. The cell was activated by extension of the contralateral shoulder, that is ,by a movement in which elbow moves backward. The call was recorded in track 21 of Cat 7 (see cortical map).

This PTN was one of the 145 neurons, activity of which was reported in Stout and Beloozerova, 2012. Excel data spreadsheet for this paper, containing, among that of 145 other neurons, the histogram of the activity of this PTN during flat surface and ladder walking along with several evaluations of the histogram is here. PTN 3182 is cell #46 by count on the second Excel sheet entitled “Selected for paper, n=145”. It can be followed on the other sheets by its unique number and the number of the file. PTN is recorded on channel 2.
This PTN was recorded simultaneously with a group of neurons from the ventrolateral thalamus, VL 115 (group) recorded in track 3 (see thalamic map). VL neurons responded to touch and movement of the contralateral hip. VL group is recorded on channel 1.

(2) main data file, clustered, txt
main data file, clustered, mat
(3) selected channels for locom_cat3M , txt (both PTN and VL cells)
(4) spike rastes, .rs format, zipped (see how to plot rasters here)

Thus, for this PTN, the data include: (1) original recording in Spike2, which includes clustering of the PTN and VL cells by IB; (2) .txt and .mat exports of this entire recording; (3) a .txt export of only the times of spikes, the beginnings of swing and stance phases of the stride of the right forelimb; and moments of entering and exiting the test corridors; and (4) IB assessment of the activity of this PTN during flat surface and ladder-5 walking.
