Research Scientist Position
Laboratory for Neural Computation and Adaptation(W19265)


Laboratory for Neural Computation and Adaptation, Center for Brain Science (Team leader:Taro Toyoizumi)

Research area

Mathmatical Science

Research field

Our research is in the field of Computational Neuroscience. Computer models are used to study how information is processed in the brain and how the brain circuits adapt to and learn from the environment. We employ analytical techniques from statistical physics and information theory to investigate key functional properties for neural circuits. We use these techniques to reduce diverse experimental findings into a few core concepts.

We are particularly interested in activity-dependent forms of plasticity in the brain, which are known to have large impacts on learning, memory, and development. With the aid of mathematical models, we seek a theory that unites the cellular level plasticity rules and the computation. Efficacy of neurons to represent and retain information is estimated from the structure and behavior of resulting circuits.

More specifically, current interest of the lab includes:

  • Modeling learning and synaptic plasticity in the brain (Front. Comput. Neurosci. 2019; Philos. Trans. R. Soc. B. 2017; Neuron 2014; Neuron 2013) and its relation to cognitive function and mental diseases (Grant-in-Aid for Scientific Research on Innovative Areas 2018-2022; Brain Mapping by Integrated Neurotechnologies for Disease Studies).
  • Studying how complex neural activity dynamics are generated and utilized for information processing (PNAS 2017; PLOS Comput. Biol. 2018, 2015; Phys. Rev. E 2011; Phys. Rev. Lett. 2006)
  • Theoretically elucidating an optimal strategy for neural network learning and behavioral strategy and predicting experimental observations (Nat. Commun. 2019; Phys. Rev. Lett. 2017; Sci. Rep. 2018, 2016; PNAS 2005)
