Depending on the network state, certain neurons in the primary somatosensory cortex can be more or less excitable, which shapes stimulus processing in the brain. Read More

Repeatedly administered tactile simulation over a sustained period of time alters neural processing of the hand area in the brain. The observable changes over time illustrate neuroplasticity and shed new light on the process of learning. Read More
Trained musicians exhibited an increased ability to predict rhythmic patterns over non-musicians, with more subtle differences between those trained in Japanese or Western classical music styles. Read More
Astrocytes are important for uninterrupted slow wave sleep and brain rhythms that are essential for learning and memory, through mechanisms involving intracellular calcium signals. Read More
An EEG study reveals people with schizophrenia and their siblings without the disorder share patterns of brain activity that are different from people with no familial history of schizophrenia. As one sibling didn't suffer from schizophrenia, researchers say the different brain signature could serve as a biomarker for the mental health disorder. Read More
A new study provides evidence that hearing is the last sense to go during the process of active death. Many people become unresponsive during the final hours of life, however, EEG data revealed the dying brain responds to sounds throughout the final moments of life. Read More
People with dyslexia experience difficulties when acoustic variation was added to speech sounds. In the absence of the variation, neural speech sound processing was consistent between dyslexic and typical readers. Difficulties in detecting linguistically relevant information during acoustic variation in speech may contribute to a dyslexic person's deficits in forming native language phoneme representations during infancy.

The human brain avoids taking unnecessary effort while reading by regulating the resources used in order to identify the most essential information. Read More
Higher doses of ketamine administered to sheep completely reduced brain activity for a short period. Researchers report as the drug wore off and consciousness was regained, the animals' brain activity switched between high and low-frequency oscillations. The timing of the brain activity corresponds to the time human users report experiencing feelings that their brain 'disconnected' from their bodies after ketamine use. Read More
A new system for high-density EEG helps with the imaging of the origin and path of both normal and abnormal neural activity. Read More
NMDA receptor hypofunction is involved in the reduction of sleep spindles and delta oscillations, which appear in the brain during deep natural sleep. Findings confirm the role NMDA receptors play in sleep disorders that accompany psychotic states. Read More
