Mothers who breastfeed have been found to report lower levels of perceived stress and negative mood, higher levels of maternal attachment, and tend to perceive their infants more positively than mothers who formula - feed.9, 19 - 21 There is evidence to suggest that breastfeeding mothers may also spend more time in emotional care and be more sensitive to infant emotional distress cues than bottle - feeding mothers.22, 23 Relatedly, a small fMRI study of 17 mothers in the first postpartum month, found that breastfeeding mothers showed greater activation in brain areas involved in empathy and bonding than formula - feeding mothers when listening to their own infant's cry.24 These brain areas included the superior frontal gyrus, insula, precuneus, striatum and amygdala.

In the 1960s, researchers showed that adult rats continually produce neurons in a brain region called the dentate gyrus, part of the hippocampus — an area that plays an important role in acquiring new memories.

The middle and inferior temporal gyri, for example, also play roles in memory and sensory integration and have been shown to be involved in the early stages of mild cognitive impairment and Alzheimer's disease.

The researchers saw that among the PTSD group, who were all taking the drug paroxetine (sold as Paxil), the patients who showed the most improvement from the SSRI were those who showed the least activation, prior to treatment, of a brain area called the right ventrolateral prefrontal cortex, also known as the inferior frontal gyrus.

The researchers found that the portion of a brain region called the insular cortex (which is made up of gyri, or folds) showed differences in activity between men and women.

The bottom sets of scans obtained from the patient (Panel C) and the control subject (Panel D) show activation (blue) resulting from the spatial imagery task (cued with the word «navigation») as compared with rest periods, as well as the time course of the peak voxel in the parahippocampal gyrus.
