Glabellar reflex The glabellar reflex is a primitive reflex. It is elicited by tapping the forehead between the eyebrows and nose and observing that the eyes blink. Successive tapping of the glabella eventually leads to habituation with blinking being suppressed. While suppression of the glabellar reflex may not occur and/or may take longer to occur during childhood development, lack of habituation in adults is categorized as a pathologic sign (often called Myerson’s sign).

🧠The glabellar reflex, also known as the "glabellar tap sign", is a primitive reflex elicited by repetitive tapping on the forehead. Subjects blink in response to the first several taps. If the blinking persists, this is known as Myerson's sign, and is abnormal and a sign of frontal release; it is often seen in people who have Parkinson's disease.⁣ ⁣ 📝📝The afferent sensory signals are transmitted by the trigeminal nerve to the brain stem; the efferent signals go to the orbicularis oculi muscl
