Brain cellsThe human brain contains an estimated 100 billion nerve cells (blue), as well as support cells known as glia (red and green). Neuroscientists are striving to understand how these cells are born, grow, connect and work together to give rise to our thoughts and actions. (Credit: NICHD/J. Cohen)

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.

An Intricate Network: New Research Is Uncovering a More Complex Path for Memory

Mar 05, 2013

New findings reveal memory networks more intricate than previously believed. Understanding these pathways may help develop ways to enhance learning, mitigate memory disorders such as Alzheimer’s or guard against memory loss from aging.

A Conversation About Communicating Science with Kavli Institute Director Nicholas Spitzer

Dec 04, 2012

Nicholas Spitzer discusses why, in a world increasingly dependent on the knowledge and principles of science, it is more important than ever for scientists to step out of the lab and engage the public.

2012 Kavli Prize in Neuroscience: A Discussion with Cori Bargmann, Winfried Denk and Ann Graybiel

Aug 06, 2012

How does the brain gather information from the outside world and use it to guide behavior? Three neuroscientists who have spent much of their research careers trying to answer that question were awarded the 2012 Kavli Prize in Neuroscience.

The Fantastic Plastic Brain

Jul 26, 2012

Recent research is beginning to answer these fundamental questions by exploring the plasticity of the adult brain—its ability to readily be shaped by experience. Contrary to the common assumption that you can’t teach an old dog new tricks, there is increasingly strong evidence that the adult human brain is remarkably malleable and capable of new feats even in the last decades of life.

At the Centre of It All

Apr 28, 2012

Kavli Institute directors Edvard and May-Britt Moser have just established the Norwegian Brain Centre at Norwegian University of Science and Technology in Trondheim. WIth its opening, the Centre becomes one of the largest of its kind worldwide.

Extreme Machines: What Science Needs from Computers

Apr 17, 2012

Computers are the workhorses of science. Without their power to crunch numbers, control instruments, turn raw data into intelligible patterns or pictures and test theories with simulations, most of what we now know about ourselves and the universe might still be a mystery. 

A New Window on the Life of the Brain

Feb 24, 2012

A new study of remarkable size and scope offers clues to how the human brain develops, from its early stages into old age. The landmark research found that gene expression in the human brain is exquisitely choreographed across developmental periods and brain regions.

Recipe for a Robot: What It Takes to Make a Social Robot

Jan 12, 2012

Scientists and engineers are improving how social robots are able to help patients undergoing physical rehabilitation, act as teaching aides, work in nursing homes, and be used for other dynamic purposes.

The Brain on Trial

Dec 01, 2011

The Kavli Foundation holds a roundtable to explore how advances in neuroscience are posing serious challenges for the judicial system, as well as possible solutions for the treatment of criminals. Participants in the discussion are Alan Leshner, Jay Giedd and Martha Farah.

Diseases In A Dish: Modeling Mental Disorders

Oct 07, 2011

Using skin cells from patients with mental disorders, scientists are creating brain cells that are now providing extraordinary insights into afflictions like schizophrenia and Parkinson’s disease.
