Gagging
Examples of reflexes that last into adulthood are: Blinking reflex: blinking the eyes when they are touched or when a sudden bright light appears Cough reflex: coughing when the airway is stimulated Gag reflex: gagging when the throat or back of the mouth [medlineplus.gov]
These include the gag reflex, which causes gagging when the throat is stimulated. However, other reflexes are unique to infants, and they typically grow out of these reflexes within a few months of birth. [healthline.com]

Grasp Reflex in Adults
reflex in adults is a pathological frontal release sign and may signify frontal lobe damage, or may be a sign of anterior cerebral artery syndrome. [ citation needed ] References [ edit ] Futagi, Yasuyuki; Toribe, Yasuhisa; Suzuki, Yasuhiro (2012). [en.wikipedia.org]
The later reemergence of a palmar grasp reflex in adult life has been linked to the presence of focal lesions or diffuse neurodegeneration involving the frontal lobes and/or their efferent connections. 1 Instructions 3 Ensure that the infant is awake. [handsurgeryresource.com]
