Excitability Of Motor Neurons Predicts Working Memory

Thursday, December 26, 2013 - 11:50 in Psychology & Sociology

A new paper studied if the excitability of the motor cortex correlates with working memory performance – and results were positive. By measuring the motor excitability, conclusions can be drawn as to general cortical excitability – as well as to cognitive performance, say the scholars from the Transfacultary Research Platform at the University of Basel.Working memory allows the temporary storage of information such as memorizing a phone number for a short period of time. Studies in animals have shown that working memory processes among others depend on the excitability of neurons in the prefrontal cortex. There is some evidence that motor neuronal excitability might be related to the neuronal excitability of other cortical regions.  read more
