Scatter Plot from Scientific Research

Left, all MOp (top) and dSTR (bottom) single units were distributed in a 2D encoding space comprising joystick location (horizontal) and load (vertical) axes (see STAR Methods). The 2D coordinates represent each units average distance from the origin during the 1-s period following the reach start. Units that passed a significance test based on each units trial-shuffled distribution were color coded according to their coordinates in the encoding space; non-significant units are marked as small gray circles. See Figure S7 for more example units. The color-coded numbers represent the percentage of encoding units classified into the 8 equidistant encoding groups. Right, quiver plots summarize the distribution of units within the encoding space. The counts were normalized across brain regions for inter-regional comparison and translated into the length of arrowed vectors.
