A primitive reflex present from birth to three months of age, triggered by placing a finger across the infant’s palm and eliciting a strong grip around the finger.
A normal newborn reflex in which the baby’s fingers spontaneously curl around any object placed within them and do not spontaneously let go. This reflex usually diminishes by age 3 to 4 months and disappears before age 6 months. The reflex reappears later in life in diseases that affect the brain’s frontal lobes.
