Withdrawal from psychostimulants restructures functional architecture of brain

Researchers describe how withdrawal from nicotine, methamphetamine and cocaine alters the functional architecture and patterns in the brains of mice, compared to control animals, a key to developing addiction treatments.

When it comes to communication skills, maybe we’re born with it?

A neuroscientist and speech pathologist, led a study that uncovered how neural networks in infants influence their language learning skills in early childhood.

Infection hinders blood vessel repair following traumatic brain or cerebrovascular injuries

Traumatic brain injury (TBI) and other injuries to blood vessels in the brain, like stroke, are a leading cause of long-term disability or death. Researchers have found a possible explanation for why some patients recover much more poorly from brain in…

Different types of cancers are likely to spread to specific areas of the brain

Brain metastasis occurs when cancer in one part of the body spreads to the brain. The lifetime incidence of such metastatic brain tumors in cancer patients is between 20%-45%, research shows.

Few studies have explored the effect of psychological stressors on behavior, and neurogenesis, in the context of depression. With the elucidation of a vicarious social defeat stress mouse model, scientists have successfully endeavored in connecting the…

Human learning can be duplicated in solid matter

Researchers have found that learning — a universal feature of intelligence in living beings — can be mimicked in synthetic matter, a discovery that in turn could inspire new algorithms for artificial intelligence (AI).

Which types of brain activity support conscious experiences?

Our subjective experience appears to us in a continuous stream of integrated information, and researchers now explore the question: Which characteristics should brain activity have to support this type of conscious experiences? The group searched for i…

Researchers study recurrent neural network structure in the brain

A recurrent neural network structure exists in the most important part of the brain — the frontal cortex — and this network is less complex than has been thought and mostly unidirectional, new research shows.

Our eyes and brain work together to create a ‘pipeline’ of meaning – new study

Humans read by ‘pre-processing’ written words to create a pipeline of meaning, according to new research.
