Individuals With High Level of Schizotypal Traits Exhibit Altered Brain Structural and Functional Connectivity

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.

Melatonin Linked to Improved Brain Function in Child Concussion

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.

Highly Reproducible Sex Differences in Aspects of Human Brain Anatomy

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.

Alcohol dependence results in brain-wide remodeling of functional architecture

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.

Brain anatomy changes with maturation to adolescence

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.

Genes associated with left-handedness linked with shape of the brain’s language regions

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.

New nerve pathway that connects the foot and face on same side of body map discovered

Newly identified nerve pathway, which runs down the same side of the body, may bypass a damaged spinal cord. The findings could shed light on some neurological disorders such as referred itch or jogger's migraine.
