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).

[Medical student] Glabella tap reflex คือ การเคาะบริเวณหน้าผาก กล้ามเนื้อ orbicularis oculi จะหดตัวทำให้ตากระพริบ ....เกิดจาก reflex ผ่าน afferent sensory โดย trigerminal nerve และ efferent ผ่าน facial nerve กล้ามเนื้อ orbicularis oculi จะหดตัวทำให้ตากระพริบ .....ปกติจะหยุดกระพริบหลังจากเคาะซ้ำๆ 5 – 10 ครั้ง เนื่องจาก frontal lobe จะยับยั้ง reflex นี้ไว้ ถ้ากระพริบต่อเนื่องเรียกว่า Myerson sign หรือ Glabellar tap positive เดิมทีตั้งแต่ ปี ค.ศ. 1946 ใช้เป็น Sign’s ที่ช่วยในการวินิจฉัย Parkinson’s
