Discovery of cortical cells that encode multiple actions efficiently in two-dimensional categories

The research group of Professor Hajime Mushiake and Research Associate Toshi Nakajima of the Department of Physiology at the Tohoku University Graduate School of Medicine University has discovered, through experimentation with monkeys, that medial motor areas in the cortex efficiently represent multiple sequences of arm movements as a combination of two types of category-encoding neurons.

The research results have elucidated the encoding principles that regulate multiple behavioral sequences within the brain and are expected to provide possibilities for future applications in new treatments for neuronal dysfunctions and in human machine interfaces.

The research results will be published in the online edition of the American science journal, Journal of Neuroscience on September 26 (September 25, local time). The research was conducted through grants from the Japan Science and Technology Agency's Create Revolutionary Technological Seeds for Science and Technology Innovation (CREST) and the Ministry of Education, Culture, Sports, Science and Technology's Global Centers of Excellence (COE) programs.
