Structural and functional coupling in visual areas of the mouse brain can be detected at sub-cellular resolution in vitro. Read More
People with schizotypal traits exhibited increased structural connectivity probability within the task control network and default mode network. They also had increased variability and decreased stability of functional connectivity within the DMN and between the auditory and subcortical networks. Read More
Researchers identified a specific neural network that positively responds to melatonin following concussion in children. Results suggest melatonin may help compensate for normal brain function that has been interrupted due to injury caused by concussion and helps prevent sleep disturbances. Read More
Analysis of over 2,000 brain scans revealed evidence of highly reproducible sex differences in the volume of different regions of the brain. On average, females had greater cortical volume in the medial and lateral prefrontal cortex, orbitofrontal cortex, superior temporal cortex, and lateral parietal cortex. Males had increased volume in the ventral temporal and occipital brain regions. Gene expression data suggest the potential role of sex chromosomes that contribute to the differences. Read More
Using a novel imaging technique, researchers produce a whole mouse brain atlas, which reveals how alcohol addiction, and abstinence, alter the functional architecture of the brain. Read More
Reduced gray matter volume in the insula and dorsolateral prefrontal cortex may represent a genetically conferred predispositional risk factor for alcohol use disorder. Read More
The Golden Ratio was noted in the human skull dimensions, but not in other mammals. The findings may have important anthropological and evolutionary implications. Read More
White matter tracts show increasing maturation with age from the back to the front of the brain. The maturations begin as a child reaches 9-12 years of age. The maturity correlates with a critical and formative period of development. Read More
Four genetic regions have been identified as playing a role in left-handedness. Three of the four genes were associated with proteins involved in brain development and structure. Neuroimaging revealed those who were left-handed had increased functional connectivity between left and right language networks. Researchers also found correlations between the genetic regions associated with left-handedness and slightly reduced Parkinson's risk, but a slightly increased risk for schizophrenia. Read More
Selective breeding has altered brain anatomy in dogs. Neuroimaging of 33 dog breeds revealed brain structures varied across breeds, and the variations are associated with specific behaviors. Read More
Brain networks are spatially and functionally fluid, and not static, as previously believed. Read More
Using resting state fMRI, researchers discover pig brains may be better models for studying human neurological conditions than previously thought. Read More
