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.

gyrus gets passed along to the CA3, and then on to CA1.
The extra attention the offspring received in the enriched environments — nursing, licking and grooming — translated to denser nerve growth in the dentate
gyrus, which is in the hippocampus, the brain's memory warehouse believed responsible for learning and storing short - term memories.
The result fit with prior research indicating that accelerated growth of new brain cells in the dentate
gyrus, in a process called neurogenesis, is necessary for antidepressants to cure rats of their depression.
In a study published in the June American Journal of Psychiatry, Saxena reported that hoarders have lower activity in the cingulate
gyrus — a structure that runs through the middle of the brain, front to back — particularly in areas known to be involved in decision making and focusing attention.
And even well - adjusted adolescents may be primed to choose the heart over the head — or, perhaps we should now say, the ventral striatum over the inferior frontal
gyrus.
The scientists discovered a unique brain region within the mid frontal
gyrus that identifies placebo pill responders in one trial and can be validated (95 percent correct) in the placebo group of a second trial.
At those moments, part of the cognitive control network, called the inferior frontal
gyrus, was more active than it was at other times.
The team found a smaller aura of activity originating from the curved dentate
gyrus than in normal rats [see image below].
«In particular, obesity led to altered activity in a part of the brain linked to the development of Alzheimer's disease — the posterior cingulate
gyrus.
The so - called Inferior frontal
gyrus (IFG) was activated more during sequences which were ungrammatical than grammatical, although brain activity was more weighted towards the right hemisphere.
In all of the brains, the researchers found evidence of newborn neurons in the dentate
gyrus, the part of the hippocampus where neurons are born.
The researchers hypothesized bilateral activation of the inferior frontal
gyrus, the anatomical structure housing Broca's area, during ungrammatical sequences compared to grammatical sequences.
Blue marks the dentate
gyrus, where new nerve cells are born.
Now a research team, led by Dr Diego Gomez - Nicola from the Centre for Biological Sciences at the University of Southampton, has detected increased neurogenesis in the dentate
gyrus that partially counteracts neuronal loss.
Dentate
gyrus dysfunction also is implicated in psychiatric disorders, including schizophrenia.
However, the brain has some self - repairing potential that accounts for the renewal of certain neuronal populations living in the dentate
gyrus, a simple cortical region that is part of the larger functional brain system controlling learning and memory, the hippocampus.
Critically, the superior temporal
gyrus of the right temporal lobe maintained a steady, baseline activity throughout the game but became more active when one player suddenly understood what the other player was trying to communicate.
Peering into the subjects» brains using functional magnetic resonance imaging, the researchers found that on average the regions of the brain that usually light up when an individual is aroused, the hypothalamus and fusiform
gyrus, responded normally to moderately erotic images.
One interesting finding was the association between phonological deficits and lesions in the anterior temporal lobe and mid-fusiform
gyrus.
Blood glucose is not alone in selectively affecting dentate
gyrus performance.
There was also less activity in an area called the supramarginal
gyrus.
Some may be «clumped,» affecting just one
gyrus [fold] of the brain, disrupting just a little part of the cortex at a time.»
Being nice «The great complexity of human social interactions and the huge variation in what we find rewarding compared with other primates prompts questions about whether the anterior cingulate
gyrus operates similarly in the human brain,» Matthew Apps and Narender Ramnani, who work on neuroimaging and human cognition at Royal Holloway, University of London, UK, told Nature in an email.
Led by Dr. Bart Rypma, Meadows Foundation Chair at the Center for BrainHealth, the study found that the amount of dopamine relative to the amount of brain activity in the fusiform
gyrus strongly predicted the ability to recognize faces.
Non-spatially oriented brains have more grey matter in the left angular
gyrus, an area associated with semantic and conceptual processing.
Although the fusiform
gyrus has been previously established as an area of the brain related to facial recognition, this is the first time scientists have made a connection between dopamine and facial recognition.
For example, stimulating an area close to the supramarginal
gyrus can elicit out - of - body experiences.
They found that elevated levels impaired function of a section of the hippocampus called the dentate
gyrus, which is a «hotspot» of age - related impairment, according to study author Scott Small, a neurologist at Columbia University.

gyrus and precuneus.

gyrus, insula and putamen of the brain — was decoupled in depressed patients.
This involved running a painless electrical current between two electrodes placed on the participant's scalp, to activate the right inferior frontal
gyrus, a part of the brain that controls inhibitory control.
For instance, musicians who practice consistently develop a larger Heschl's
gyrus, an area involved in processing sound.

gyrus.
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.
