Motor cortical recordings often show waves of oscillatory activity around 25Hz.
These synchronise with similar oscillations in contralateral muscles. Although much studied, until now there have been few plausible suggestions as to what their functional role might be.
In this seminar, I will examine certain pieces of experimental data which do not fit with established ideas about these oscillations. From these, I will suggest a speculative hypothesis of what their functional role might be, namely to achieve a proprioceptive recalibration of the motor system.
I will then present some of our more recent data to support this.
