Humans can perform short-term actions while remaining aware of longer-term goals. Evidence suggests that prefrontal areas coordinate motor activity when such goals are being aimed at. The more that abstract rules are involved, the more there is a combination of theta (4-8 Hz) and high gamma (80-150 Hz) phase together with inter-regional information encoding in the frontal cortex.

Neural antecedents of self-initiated actions in secondary motor cortex Murikami, M. Vicente, Gil Costa & Z. Mainen Nature Neuroscience, vol. 17, No. 11, pp. 1574-82, November 2014 www.nature.com/neuro Summary and review of the above paper INTRODUCTION: In a very guarded fashion, the authors of this paper cast doubt on the Libet-based orthodoxy where pre-conscious activity in the brain precludes the possibility of conscious will. Their research suggests that a simple threshold Read more […]
