There are established ways to address these questions: we can assess unusual movements, analyze changes in mood and thinking, and take images
of the brain areas involved in HD.
Researchers believe that interactions between vitamin D and dopamine in the brain of the fetus may play a crucial role in the neurological development
of brain areas controlling motor and social development.
Several of the brain areas that had lost gray matter during pregnancy responded with the strongest neural activity to their own babies as opposed to the photos of other infants.
This is a
photograph of brain areas whose pattern of activation matched significantly while watching a video and remembering that same video.
It appears that, compared to interactions with computers, social interaction «activates» a consistent
set of brain areas.
Studies in other mammals (rats and apes) showed that rough - and - tumble play is critical for the development
of the brain area responsible for executive control.
Even more surprising, subjects who had grown up in a city showed higher activation
of a brain area called the anterior cingulate cortex, essentially the amygdala's boss, even if they had later moved to the suburbs or country.
The researchers found that, on average, the more money a participant gave away, and the stronger the feelings of gratitude they reported feeling, the more activity they exhibited in a
range of brain areas in the frontal, parietal, and occipital regions.
Neurons in the shell surrounding the established vocal centers of the parrot brain play a part in vocal learning and other complex motor behaviors, resolving controversies over the
size of brain areas involved in song and speech imitation.
Researchers have found that
disconnections of brain areas involved in attention and visual processing may contribute to visual hallucinations in individuals with Parkinson's disease, according to a new study published online in the journal Radiology.
The N170 component reflects
activation of brain areas sensitive to faces, indicating that faces activated these areas more strongly after being administered oxytocin.
«This connection between an innate call and the
activity of a brain area important to learned vocalisations suggests that during the evolution of songbirds, the role of the song area in the brain changed from being a simple vocalisation system for innate calls to a specialised neural network for learned songs,» concludes Manfred Gahr, coordinator of the study.
A brief period of postnatal visual deprivation, when early in life, drives a
rewiring of the brain areas involved in visual processing, even if the visual restoration is completed well before the baby reaches one year of age, researchers at the University of Trento, McMaster University, and the University of Montreal revealed in Current Biology.
In this study, published in Neuron last year, Greene and Shenhav observed that as the subjects made their decisions, they tapped a fascinating
selection of brain areas: the insula, normally used to manage probability and risk, and the ventral striatum, which tracks magnitude.
Beyond mapping the precise
locations of the brain areas controlling these movements for the first time, Chang and colleagues also recorded and analyzed patterns of neuron activity in those areas.
To validate the sensor, the researchers successfully measured the expected effect of the SSRI fluoxetine, commonly called Prozac, on serotonin transporters in six
subregions of a brain area known as the basal ganglia.
The experts emphasize the importance
of the brain areas related with attention control in the control of movements, which «may also suggest some therapeutic routes,» such as complementing «mobility therapies based on physiotherapy with another type of cognitive training that increases the attention of patients.»
«It really hasn't been explored when these activity networks — these
collections of brain areas that start to work together in the brain — emerge and what types of cells and tissues they emerge in,» says Colin Studholme, Ph.D., a professor with joint appointments in pediatrics and bioengineering at the University of Washington and senior author of the paper.
More than a
dozen of brain areas were found to respond more strongly to lateralized multisensory stimuli than to lateralized unisensory stimuli, the scientists reported in their paper, and the response was further enhanced when the multisensory stimuli are in perceptual sync.
Our current goal is to manipulate the activity of neurons in a specific node of this network, the prefrontal cortex, to test specific hypotheses regarding the
role of this brain area in these two basic functions.
It was
atrophy of a brain area, which is a normal consequence of aging, that was involved in generating deep sleep.
Diffusion tensor imaging (DTI)- used to document changes in the brain's structure over a period of time and allows the physician to study the connections between different areas of the brain
According to Dr. Kathleen Page, from the University of Southern California in Los Angeles, several studies have found that fructose is a weaker
suppressor of brain areas which regulate appetite and desire to eat when compared to glucose.
Interestingly, during adolescence, the PFC show both over-communication and under - communication with a
number of brain areas.9 Over-communication with several brain regions (especially other frontal areas) likely serves to inhibit a number of desired behaviours thereby possibly contributing to increased laziness / boredom seen during the teenage years.
Mothers» support linked to robust
growth of brain area involved in learning, memory, stress response
Animal studies have shown that direct glucocorticoid exposure results in a loss of pyramidal neurons and dendritic branching in the hippocampus, meaning that the organic
structure of this brain area was affected by this hormone, likely resulting in a decrease neuronal synapses that would facilitate integration.
The KU Leuven scientists measured the electrical activity of individual cells in one
of the brain areas responsible for body recognition in rhesus monkeys.
In the realm of relationships, this mingling of the less and more - concrete means that attachment experiences with specific others, their unconscious emotional tone, and the temperatures they actually feel activate and are stored in overlapping
networks of brain areas.
For example, in 2012, Berman and colleagues reported on how genetic variation shapes the structure and function
of a brain area called the Insula in the autism - related disorder Williams Syndrome.
The brain regions most affected are those involved in reward, emotion and learning — although it isn't clear yet whether the smaller than average
size of these brain areas could be a cause or effect of addiction.
