Teppei Ebina, Lecturer at the University of Tokyo, and his colleagues conducted chronic calcium imaging in the motor cortex of common marmosets during the learning of a two-target reaching task. They found that neurons in the dorsocaudal premotor cortex dynamically changed their preferred movement direction during the learning while those in the primary motor cortex stably retained the direction.
The research results were published in “Nature Communications”, and were featured in a press release.
