Dysphoric milk ejection reflex (D-MER) is a condition in which women who breastfeed develop negative emotions that begin just before the milk ejection reflex and last less than a few minutes. [2] It is different from postpartum depression , breastfeeding aversion response (BAR), [ 1 ] or a dislike of breastfeeding. [ 2 ]
Overactive let-down (OALD) is the forceful ejection of milk from the breast during breastfeeding. In some women it occurs only with the first let-down in a feeding, occasionally women may have multiple strong letdowns during a feeding. OALD can make breastfeeding difficult and can be the source of some breastfeeding complications. It may also ...
[10]: 18–21 [25] This process is known as the milk ejection reflex, or let-down. [10]: 18–21 Because of oxytocin's dual activity at the breast and the uterus, breastfeeding mothers may also experience uterine cramping at the time of breastfeeding, for the first several days to weeks. [25]
Milk ejection is initiated in the mother's breast by the act of suckling by the baby. The milk ejection reflex (also called let-down reflex) is not always consistent, especially at first. Once a woman is conditioned to nursing, let-down can be triggered by a variety of stimuli, including the sound of any baby.
When the infant suckles or stimulates the nipple, oxytocin levels rise and small muscles in the breast contract, moving the milk through the milk ducts. The result of nipple stimulation by the infant helps to move breast milk out through the ducts and to the nipple. This contraction of milk is called the "let-down reflex". [19]

A plantar reflex is a normal reflex that involves plantar flexion of the foot, which moves toes away from the shin and curls them down. An abnormal plantar reflex (Babinski sign) occurs when upper motor neuron control over the flexion reflex circuit is interrupted. This results in a dorsiflexion of the foot (foot angles towards the shin, big ...
The neuroscience of free will encompasses two main fields of study: volition and agency. Volition, the study of voluntary actions, is difficult to define. [citation needed] If human actions are considered as lying along a spectrum based on conscious involvement in initiating the actions, then reflexes would be on one end, and fully voluntary actions would be on the other.
