Brain Region Helps Tune Our Hearing to Focus on Important Sounds

A new study uncovers how the orbitofrontal cortex (OFC) aids the auditory cortex in adapting to different hearing contexts. Researchers found that the OFC sends signals to the auditory cortex to help switch between passive and active listening. This discovery enhances our understanding of how the brain filters and reacts to sounds, with implications for treating neurodevelopmental disorders. The findings highlight the OFC's crucial role in managing auditory attention.

Study Links Brain Region to Paranoia

Researchers discovered that a specific brain region, the mediodorsal thalamus, may provoke feelings of paranoia. By aligning data from studies on monkeys and humans, they found that lesions in this brain region led to erratic behavior and increased perceptions of environmental volatility.

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.
