The brain is the most complex organ of the body. Cells within the brain, called neurons, communicate with each other to influence vision, movement, memories, emotion—just about every activity that governs how we live our lives. So it’s vitally important to understand how these 100 billion cells form, grow, connect and communicate.

In the human brain, synapses are the contact points where neurons communicate. Faulty communication between neurons at synapses is a hallmark of many brain disorders, including autism, mental retardation, and schizophrenia. Although we understand the important role of the signal transmission at synapses, we need a clearer picture of the mechanisms behind it. Understanding what is happening in a healthy brain will enable us to understand what is happening in brains that don’t function normally.

Dr. Pascal Kaeser, Assistant Professor of Neurology at Harvard University, is using his 2013 BRF Seed Grant to decipher what is regulating the signal transmission at synapses. He is focusing on molecules that have been shown to be involved in this regulation of synapses but their exact role is not understood. This knowledge will be critical to advance our understanding of the pathological mechanisms in brain disorders and may uncover novel therapeutic targets for a variety of neurological diseases. The BRF is pleased to be able to support Dr. Kaeser’s critical research, as well as the leading-edge research of all our Seed Grant winners.
