The representation of fingers in the first somatosensory cortex was studied in conscious monkeys by recording single neuronal activity, and the following results were obtained: (1) In area 3a, most neurons responded to joint manipulation or other types of deep stimuli. The representation of five fingers was somatotopically arranged. (2) In area 3b, 77.7% and 20.9% of identified neurons responded to cutaneous and deep stimuli respectively. (3) Neurons responding to light mechanical stimuli and… CONTINUE READING
