Fig. 2: Wide-field one-photon calcium imaging during TTR training sessions.
a The one-photon imaging window of marmoset 1. White lines indicate boundaries of cortical areas inferred from the ICMS motor map and the marmoset brain atlas. The corresponding area names and/or numbers are also shown. Trial-averaged pseudo-colored z-scored ΔF/F images at 0.5-s time points between 0.5 s before and 3.0 s after the cue onset (b), and at 0.5-s time points between 1.5 s before and 2.0 s after the movement onset (c), for successful pull and push trials in sessions 5 and 15 in marmoset 1. d, e ΔF/F traces of area-averaged PMdr (green), PMdc (brown), and M1 (orange) in pull (top) and push (middle) trials in early (left) and late (right) sessions of marmoset 1. The lines in the top 2 panels indicate the area averaged ΔF/F. In the bottom panels, the data are presented as mean ± SEM. In (d) the activity is aligned to the onset of the target presentation. Colored arrowheads indicate Tpeak of the corresponding colored traces. The bottom image shows the averaged Y-axial pole trajectory for pull (red) and push (blue) trials. In (e) the activity is aligned to the onset of the pole movement. A histogram of the cue onset timing is overlaid. Source data are provided as the Source Data file.
