The motor cortex plays a role in determining which of three different facial movements is acquired in Pavlovian conditioning experiments. Three separate facial reflexes can be distinguished by recording electromyographic activity from the orbicularis oculi (eye blink) and levator orii (nose twitch) muscles. One in a pure eye blink; a second is a nose twitch; the third is a compound eye blink and nose twitch. Which of these movements is elicited by a click (conditioned stimulus) following… CONTINUE READING
