Columns show the number of animals prepared for chronic versus acute electrophysiology and the quantity of data collected from the two preparations. Subcategories of neurons are those related to sensorimotor activity of a specific body part and a (sensory) subset of body part neurons that fired in response to passive manipulation and/or cutaneous stimulation. Data in parentheses are numbers obtained from chronically implanted animals under anesthesia.
