Stacked Bar Plot from Scientific Research

Bar plots depict the percentage of cortical neurons showing a response (grey) and no response (white) to mechanical stimuli of a bead indenting the soma at various indentation speeds. The neurons were indented with a 5-μm-diameter silica bead, glued to the AFM cantilever, by applying a force of 200 nN ( ~ 5 kPa). The response of the neurons expressing the genetically encoded calcium sensor GcaMP6s was monitored by confocal microscopy. P values of the χ 2 analysis for different conditions are given above the bars in a.
