To Dr. Baraban, one of the most fascinating questions facing neuroscience is how the nervous system continuously adapts to changes in the environment by learning new associations and ignoring old ones that are no longer valid. At the molecular level, this plasticity of the nervous system is mediated by signaling pathways that regulate neuronal morphology, the form and structure of nerve cells; and synaptic efficacy, the ease of communication between neurons. Defects in these processes underlie a wide range of psychiatric disorders.

Dr. Baraban and his team are studying the signaling pathways that mediate neuronal plasticity. Among the subjects under investigation are: a protein that triggers rapid changes in dendritic morphology (dendrites are messagecarrying extensions from neurons); a pair of proteins that target messenger RNAs, bearers of the genetic message, to the vicinity of synapses; and a gene that regulates appetitive responses to opiates.

Dr. Baraban joined Johns Hopkins University School of Medicine as a postdoctoral fellow in Dr. Solomon Snyder’s laboratory.

We Are

The Brain & Behavior Research Foundation is a global nonprofit organization focused on improving the understanding, prevention and treatment of psychiatric and mental illnesses.

Beginning in 1987, the Brain & Behavior Research Foundation was providing seed money to neuroscientists to invest in “out of the box” research that the government and other sources were unwilling to fund. Today, Brain & Behavior Research Foundation is still the leading, private philanthropy in the world in this space.
