Brain waves shape the words we hear

Researchers found that brain waves bias perception towards more probable sounds or words when stimuli were presented in less 'excitable' brain wave phases. This suggests that both the probability and timing of events influence what people perceive. The study has important implications for theories of predictive coding and language comp...

U.S. health departments experience workforce shortages and struggle to reach adequate staffing levels in public health

A new study by Columbia University Mailman School of Public Health reveals that US health departments struggle with workforce shortages and inadequate staffing levels. The main barriers to addressing this issue are insufficient funding, a shortage of people with public health training, and lengthy hiring processes.

Mapping the mind with BARseq

Researchers have used BARseq to map the brains of nine mice, tracing gene expression in the visual cortex. The results show that losing vision leads to changes in gene expression across neighboring cortical areas, highlighting the complex connections between brain regions.
