One hypothesis for how autism develops is excessive neuron production in the prenatal period, leading to a transient but significant increase in brain size in the first few years of life in about ...

To stay in balance, the brain depends on two types of neurons: Excitatory neurons (in white), which increase activity, and inhibitory neurons (in black), which damp down signals. Scientists have now ...

Just a few weeks after conception, stem cells are already orchestrating the future structure of the human brain. A new Yale-led study shows that, early in development, molecular “traffic cops” known ...

The study shows prenatal air pollution exposure correlates with slower brain myelination in infants, emphasizing the need for ...

Researchers at the Central Institute of Mental Health (CIMH) in Mannheim, together with international partners, have ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that ...

An international study changes the view that exposure to the toxic metal lead is largely a post-industrial phenomenon. The ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...
