Nicholas Cain, Ph.D.

Scientist II

Nicholas Cain is a scientist in the Allen Institute's neural coding program, where he develops mathematical models of neural dynamics that aim to discover how neural systems process information about the environment. By applying mathematical theories of network dynamics and processing to the quantitative data collected at the Allen Institute, he hopes to link theory and experiment through detailed mathematical models of neural function. His research interests include theoretical models of decision-making and accumulation of sensory evidence by circuits involved in short-term working memory. Cain received a B.S. in mathematics from Davidson College, and a M.S. and Ph.D. in applied mathematics from the University of Washington.

Research Interests

Research Interests Since joining the modeling, analysis, and theory group at the Allen Institute in 2012, I have contributed to two main Institute-wide platforms. The first, ongoing, contribution is to the Allen Mouse Brain Connectivity Atlas, where I helped formulate reduced models of brain connectivity based on raw fluorescence data, and began a graph theoretic analysis of the whole mouse brain connectivity structure. I have also worked with other members of the modeling team to construct a large-scale population density modeling framework (DiPDE) capable of efficiently simulating the voltage distribution of coupled neuronal populations. These two projects converge in a broader project, in which whole-brain connectivity data are being used to parameterize large-scale neuronal simulations.
