Through development, the walls of these vesicles will differentiate into adult brain structures. (msu.edu)

The menopause transition (MT) is a neuro-endocrine process that impacts the aging trajectories of multiple organ and systems including the brain. (imsociety.org)

Implementing a series of sampling procedures to equalize the size and proportion of the datasets, our results indicated that females exhibit stronger interhemispheric co-activation than males, suggesting that the female brain is less lateralized and more integrated than that of males. (springer.com)
To make the new map, the team overlaid information, such as gene expression data, from many other datasets onto structural imaging data from the Allen Institute for Brain Science in Seattle. (spectrumnews.org)

We found that activation of the brain's executive-control centers - the parts of the brain that enable you to plan, organize and manage your activities - is negatively associated with creative task performance," said Reiss, who holds the Howard C. Robbins Professorship in Psychiatry and the Behavioral Sciences. (stanford.edu)

Comparison to existing methods: Comparison to a histological verification method suggested that, under conditions where individual wires are possible to track in slices, a 90% correspondence could be achieved in terms of the number of electrodes groups that could be reliably assigned to the same anatomical structure.

The objective of this article is to describe how the 6 concept-mapping phases originally outlined by William Trochim guided our strategic planning process and how we adjusted the specific methods in the first 2 phases to meet the specialized needs and requirements to create The Healthy Brain Initiative: A National Public Health Road Map to Maintaining Cognitive Health .

Uncovering a biomarker, like brain structure during infancy, would allow susceptible children to receive the support and interventions they need," write the investigators. (genengnews.com)

However, there are knowledge gaps concerning the longitudinal relationships between the brain, motor, and cognitive development during the first few years of life, as well as the influence of socioeconomic factors and parental stress and their impact on these domains. (auburn.edu)

At this CNS symposium, the speakers showed how different models can help us better understand brain structural organization and how this particular organization constrains cognitive processes. (lifeboat.com)

Brain Behav Immun;113: 166-175, 2023 10. (bvsalud.org)

Past research has found that people with larger brains do tend to have a higher IQ, but the relationship is subtle - brain size only accounts for around 5 per cent of the variation in IQ, says Raznahan. (newscientist.com)
For example, at any time during one's life, a brain region's density may increase owing to more activity, leading to a subtle rise in the volume of local gray matter ," said Busatto. (medicalxpress.com)

Bullying and Our Mental Health: How Does It Affect Our Kids' Brains? (discovermagazine.com)
Armin Raznahan at the US National Institute of Mental Health in Maryland and his colleagues discovered this by comparing brain images from around 3,000 people. (newscientist.com)
Using data from the UK Biobank for participants primarily of European ancestry aged 38-73 years, including 94% white people, we identified a nonlinear association between sleep, with approximately 7 h as the optimal sleep duration, and genetic and cognitive factors, brain structure, and mental health as key measures. (nature.com)
Understanding the patterns of brain functioning of individuals exposed to 9/11 as children is essential to safeguarding their mental health. (cdc.gov)

Notably, GMV recovery and in vivo brain mitochondria ATP production correlated with preservation of cognitive performance in the postmenopausal stage, suggesting adaptive compensatory processes. (imsociety.org)

The progression of activity through the brain resembles a multi-dimensional sandcastle that materializes out of the sand and then disintegrates. (bigthink.com)
Investigators at Stanford University have found a surprising link between creative problem-solving and heightened activity in the cerebellum, a structure located in the back of the brain and more typically thought of as the body's movement-coordination center. (stanford.edu)
The results of the two studies show that both brain structure and memory are linked to the activity of genes that also perform important immune regulatory functions in the blood. (unibas.ch)
Electrical brain activity measured in bearded dragons suggests these patterns evolved in the common ancestor of mammals, birds, and reptiles. (aaas.org)
Conclusions: The herein reported semi-automated procedure to verify anatomical targeting of brain structures in the rodent brain could help increasing the quality and reproducibility of acquired neurophysiological data by reducing the risk of assigning recorded brain activity to incorrectly identified anatomical locations. (lu.se)
The activity of complexes II and III of mitochondrial ETC from liver, brain, and heart showed greater inhibition by Cd than the other complexes. (cdc.gov)
Tinnitus and temporary hearing loss result in differential noise -induced spatial reorganization of brain activity. (cdc.gov)

To investigate the combined effect of EPA/DHA and cocoa flavanols (OM3FLAV) on cognitive performance and brain structures in older adults with memory complaints. (qub.ac.uk)
