While many past studies have tried to better understand the neural underpinnings of handwriting and other complex human motor capabilities, these have not yet been fully elucidated.

> "Researchers at Zhejiang University in China recently carried out a study aimed at further exploring the role of the human motor cortex in the encoding of intricate handwriting, such as Chinese characters. Their findings, published in Nature Human Behavior, suggest that this encoding unfolds via a sequence of stable neural states.

> "'The experiment task was simple," explained Qi. "We asked our participant to write Chinese characters one by one, with the guidance of a video, just like a karaoke game for writing. We recorded single-unit MC neural activity from his motor cortex (MC) with two microelectrode arrays as he performed the handwriting task."
> 
> "The brain activity recordings gathered by the researchers provided new interesting insights into the underpinnings of handwriting, suggesting that the motor cortex encodes complex handwriting by breaking it into a series of small movement segments or states. In their paper, Qi and her colleagues hypothesize that these states are the primitive units of movement encoding.

In the future, their findings could inform the development of new BCIs that allow users to write on a computer via their brain signals."
