A new study has found a significant association between activity in the ventromedial prefrontal cortex and individual differences in mood. The researchers used brain imaging techniques to record brain activity in 89 individuals, who were asked about their experiences with unpleasant moods.
Researchers found that brains of blind-from-birth individuals exhibited unique activation patterns when reading Braille, suggesting a distinct mental imagery related to language. The study suggests that early visual experience may hinder brain plasticity in certain areas.
Researchers at Columbia University Irving Medical Center discovered that estrogen therapy improves consistency in older women, a key indicator of cognitive function. The study, which involved postmenopausal women taking hormone replacement therapy, found that estrogen users performed more consistently than those not taking the hormone.
A study by the University of Pennsylvania School of Medicine found that telling a lie and telling the truth require distinct brain activities. The research used fMRI to track brain activity in volunteers during an interrogation method, revealing increased activity in regions involved in inhibition and control when lying.
Researchers at NIMH found that brain activity patterns are unique to each category of object, with even weak responses conveying information about attributes. The study suggests a 'topography' of responses in the ventral temporal lobe of the visual cortex, enabling the brain to represent complex attributes of objects and faces
The NeuroGraph device, developed with Office of Naval Research funding, reads brain activity through a cap outfitted with electrodes to analyze differences from the norm. Pharmaceutical trials may also utilize NeuroGraph to test new drugs' efficacy on brain activity.
Researchers have developed a non-invasive optical technique to measure blood flow and oxygen consumption in the brain, allowing for simultaneous detection of both blood profusion and neural activity. This breakthrough could lead to new diagnostic, prognostic, and clinical applications.
Researchers found brain areas that track continuous event boundaries, even in passive viewing, suggesting a natural process of segmentation. This study has practical implications for designing better tools for teaching new activities and understanding perception across time.
Research suggests that maternal depression may alter frontal brain activity associated with positive emotions in infants. The study found that infants of depressed mothers exhibited less left frontal EEG activity compared to right frontal EEG activity, indicating a potential impact on emotional processing.
Researchers found distinct brain activity patterns in introverts and extroverts using PET scans. Introverts exhibit more internal processing, while extroverts show increased sensory processing.
