Researchers use electroencephalography to analyze brain activity before training on Space Fortress, a cognitive research video game. The study found that subjects with more powerful alpha wave oscillations tend to learn faster and improve reaction time and working memory.
Research finds that gently rocking hammocks facilitate faster sleep onset and boost stage N2 sleep duration. The study also discovers a lasting impact on brain activity, increasing slow oscillations and bursts of activity known as sleep spindles.
A recent study found that teenagers retain a unique and consistent pattern of underlying brain oscillations even during periods of rapid neural change, lending support to the idea of a 'brain fingerprint',
Researchers found significant patterns in discarded brain wave data, revealing connections between low-frequency and high-frequency brain waves. These connections suggest important aspects of brain architecture and function, potentially shedding light on the brain's organizational structure.
Researchers found that image recognition and memories are stronger when neurons fire in sync with local theta waves during the learning process. The study also established a direct relationship between individual neuron spike timing relative to theta oscillations and human behavior.
A distinct alpha-wave pattern occurs just before subjects make mistakes on attention-demanding tests, suggesting a potential method for monitoring attention and predicting errors. The discovery could lead to practical applications in air traffic control and new therapies for children with ADHD.
Research using EEG shows that guitarists' brains become more synchronized when playing together, with the frontal and central regions showing strong synchronization patterns. This finding has implications for how our brains interact during coordinated actions, such as music performance.
Scientists at the University of Pennsylvania identified distinct patterns of brain activity associated with successful memory formation and retrieval. The study's findings may help neurosurgeons reduce cognitive deficits in epilepsy patients by identifying neural signatures of successful memory storage and retrieval.
Researchers have discovered a way to induce slow waves typical of deep sleep using transcranial magnetic stimulation, which could lead to treatments for insomnia and improve memory consolidation. The study suggests that artificial slow waves may reduce brain overload and energy consumption during sleep.
Research suggests that adolescent brain maturation is associated with synaptic pruning, a process that eliminates weak connections between neurons. Delta wave activity declines during adolescence, beginning at around age 11, with a 25% decrease by age 14, and is related to age but not physical growth or sexual maturation.
Researchers found that schizophrenic patients lacked gamma band response, indicating defective communication between neurons, while healthy brains showed synchronized activity at 40 hertz. The study suggests that drugs promoting a normal gamma response may help alleviate schizophrenia symptoms.
Research by Harriet Hanlon explores how neural networks process language skills in boys and girls, finding differences in brain connectivity that impact reading abilities. The study suggests a balanced approach to language instruction can benefit both sexes.
