From the complexity of neural networks to basic biological functions and structures, the human brain only reluctantly reveals its secrets. Advances in neuro-imaging and molecular biology have only ...

When the Human Genome Project published the first draft of the human genome sequence in 2001, many researchers expected to be able to pinpoint protein alterations that would explain the distinctive ...

Normal aging is characterized by deficits in the cognitive domains of learning, memory and executive function. Specifically, there are age-related changes in recall of information, speed of processing ...

This video segment adapted from NOVA scienceNOW considers the purpose of sleep and, in particular, the connection it shares with memory. By studying the dreams of rats, researchers are hoping to gain ...

The entire body of a sea urchin is what researchers are now calling an “all-body brain,” with neurons that function as a brain throughout its anatomy.

Rolls and colleagues (2017) describe their work on "effective connectivity" in analyzing brain activity in depressed patients. Effective connectivity goes beyond standard functional connectivity ...

Small studies suggest that people with migraine may exhibit slight differences in brain structure and function compared to people who don’t have this neurological condition. Structural changes, such ...
