A PET neuroimaging study reveals high intensity impact training significantly increases endorphin release in brain areas associated with controlling emotion and pain.
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.
Chromosome 16p11.2 duplication impacts several different inhibitory neuron types that use GABA in brain areas that are dysfunctional in schizophrenia, including the prefrontal cortex, hippocampus, and amygdala. The chromosome 16p11.2 duplication also resulted in cognitive and social deficits that are symptomatic of schizophrenia.
Heightened states of arousal altered neural circuits in a brain area associated with decision making, resulting in some neurons changing from decision making to internal state monitors.
Researchers report chronic marijuana users show more brain activity in the mesocorticolimbic reward system when presented with cannabis cues than with natural reward cues.
A new study reveals the piriform cortex is able to archive long term memory, but requires instruction from the orbiotfrontal cortex to indicate the event is to be stored as a long-term memory.
A new study reports personality traits can help protect an individual's brain against symptoms of emotional distress, such as anxiety and depression.
The orbitofrontal cortex (OFC) appears to play a significant role in our ability to make decisions. A network connecting the OFC and nucleus accumbens translates negative outcomes into values, while the OFC-amygdala circuit helps stabilize action values.
Researchers reveal the role the orbitofrontal cortex plays in identity expectations.
