Vadim Bolshakov is a Russia-born American neuroscientist, a professor of psychiatry at Harvard Medical School. [1] He has been Director of the Cellular Neurobiology Laboratory at McLean Hospital since 1999. He received The Esther A. and Joseph Klingenstein Fund award in 2001 [2] [3] and NARSAD Distinguished Investigator award in 2013. [4]

Bolshakov is an associate editor of Frontiers in Neural Circuits, published by Frontiers, [5] an associate editor of Neurochemistry International , published by Elsevier, and a consulting editor of Amino Acids, published by Springer. [6] He presently serves on the Scientific Council of the Brain & Behavior Research Foundation. [7]

In his work, he focuses on understanding the cellular and neural network-level mechanisms of learned and innate behaviors with an emphasis on studies of fear mechanisms in the brain. He demonstrated that negatively-charged memories, resulting in uncontrollable fear and anxiety, are associated with long-term functional changes at synaptic contacts in the amygdala. [8] [9] [10] [11] He also demonstrated that these aversive memories, as well as synaptic modifications associated with them, can be controlled by the expression of specific genes in brain regions responsible for emotional states. [12] [13] Overall, his findings provide evidence that synaptic plasticity in specific projections within behavior-controlling neural circuits may serve as a cellular mechanism of memory formation and retention.
