A new study at Stanford University found that dyslexic children's brains begin to function more normally after participating in an eight-week training program. The program helped participants better understand rapidly changing sounds, leading to improved reading scores and brain activity.
A UCLA study used fMRI to scan brains while participants learned to associate names with faces, revealing areas of high activity during encoding and retrieval. The findings show that different parts of the hippocampus contribute to memory formation and retrieval in distinct ways.
Researchers found dramatic gray matter loss in the brains of men with sleep apnea, primarily in regions controlling speech production, movement, and emotion. The severity of brain damage correlated directly with disorder severity, suggesting that early brain wiring abnormalities may contribute to sleep apnea onset.
Researchers at UC Berkeley have found that the adult brain has more capabilities to change than previously thought. By exposing non-detectors to a specific odor, they showed that both nostrils can learn to detect it, suggesting a central component in the brain is involved in olfactory learning.
Researchers at Cold Spring Harbor Laboratory found that visual stimulation causes neurons to sprout new branches, a process that requires increased activity of certain proteins and decreased activity of others. The study provides insights into how visual stimulation guides the development of normal brain architecture.
Researchers discovered the brain region responsible for pattern perception, which helps humans recognize danger but also leads to superstitions. The prefrontal cortex processes information about the environment, preparing the organism to change behavior in response to patterns.
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.
A new study by UCLA researchers has created images showing how an individual's genes affect their brain structure and intelligence. The findings, published in Nature Neuroscience, reveal that genetic differences can significantly impact brain regions controlling language and reading skills.
Scientists at UCLA and NIMH detected a spreading wave of gray matter loss in schizophrenic patients, which engulfed the brain over five years, leading to worse symptoms. The study's findings may aid early detection and treatment, as well as inform future medication development.
Researchers used gene transfer to increase vasopressin receptor density in the ventral pallidum of prairie voles, leading to increased pair bonding. The study shows that higher levels of vasopressin receptor expression are associated with more affiliative behavior and stronger pair bonds.
A recent study by Cornell University neurobiologists found that female birds prefer males with the most elaborate courtship songs, which are associated with larger brain structures and improved learning abilities. This choice is thought to be driven by sexual selection, where females aim to pass on desirable traits to their offspring.
Researchers found that older adults can compensate for cognitive decline by using unique brain areas, including the hippocampus, to support performance. This suggests that aging brains are more resilient than thought, with exciting implications for memory rehabilitation.
A study by NIH/NINDS scientists mapped a specific brain region responsible for human multitasking behavior, identifying the fronto-polar prefrontal cortex (FPPC) as the key area. This finding suggests that humans have a unique ability to switch between tasks while maintaining working memory and attentional focus.
Researchers found distinct patterns of gene expression linking cognitive control regions to stress control regions in laboratory animals. The study suggests that the brain controls stress responses through inhibition, rather than excitation, and may lead to the development of future stress intervention strategies.
The University of Maryland Medical Center has successfully implanted a new device that can regulate a dangerously rapid heartbeat automatically and internally. The Metrix System TM delivers a small electrical shock to the heart, making it a more comfortable alternative to external shocks.
A team of researchers from Oregon Health & Science University has identified three gene regions in mice that are linked to an increased risk of physical dependence on alcohol. The study's findings could lead to a better understanding of alcoholism and the development of new treatments.
