Neuroscience

Neuroscience seeks to understand the most complex biological structure in the Universe, with an estimated 100 billion brain cells, or neurons, and trillions of connections between them. To make sense of the brain’s complexity, neuroscientists draw on expertise from numerous fields, including biology, physics and computer science, neurology, psychology and even philosophy. Some of the main questions they are trying to answer are: How does the brain, in which networks of cells course with electrical and chemical signals, give rise to the mind? How does the brain compute? How do we learn and remember (See "Memory")? What is the biological basis of language (See "Language")?  And what causes psychiatric and neurological illnesses (See “Brain diseases & disorders”)?

Many neuroscientists feel the field is entering a new era, spurred by new technologies and techniques (See “Neurotechnology”) with which they can finally explore the working brain and begin to answer these questions. Hand in hand with this is a surge of interest in the field among graduate students, funding agencies as well as philanthropists and private enterprises. And, since 2013, a handful of big science project have launched to study the brain including the European Commission’s Human Brain Project to create a supercomputer simulation of the human brain and the U.S. Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative (See “BRAIN Initiative”) to develop new brain research tools, along with smaller efforts in Japan, Israel and China.

For the first time, scientists have watched sleep transform the brain. The research confirms a long-standing theory about the value of sleep—and helps explain why sleep deprivation messes with our ability to remember. Four neuroscientists—Chiara Cirelli, Graham Diering, Richard Huganir and Ken Paller—discuss two breakthrough sleep studies.
