Tsuyoshi Nakajima, Post-Doctoral Fellow (Japan) 2010 - 2011

tsuyoshi

Tsuyoshi Nakajima, PhD., worked as a post doctoral researcher from 2010 - 2011 in the Rehabilitation Neuroscience Laboratory under the supervision of Prof. E. Paul Zehr.

He is interested in the neural control of locomotion (e.g. interlimb coupling), plasticity of the human spinal cord in individuals with spinal cord injury during locomotor training and function of indirect corticomotoneuronal pathways (e.g. C3-C4 propriospinal neurons) in humans. He investigated the function of spinal interneurons in cutaneous reflex pathways during remote rhythmic movement in humans.

After daily work, he enjoys cycling, hiking and drinking in Beautiful Victoria!
