Experimental time line and examples of brain sections used for morphology and electrophysiology. (a) A model depicting the experimental time line. (b) Example of a 4-mm-thick brain section obtained from the sectioning of the monkey brain in a brain matrix. The caudate is outlined in blue. The putamen is outlined in red. The caudate and putamen are separated by the internal capsule. The section is further blocked for morphological and electrophysiological analyses and is denoted by a dashed box. The red box in the putamen denotes the area in which MSNs were targeted for electrophysiological recording.
