How do we make tDCS more effective? Galea – during visuomotor adaptation task, cerebellar tDCS leads to faster acquisition, while M1 stim leads to better retention. A clear double dissociation that highlights distinct roles of the two structures during motor learning. Pope – subtraction vs addition dual tasks. Subtraction the harder task and tDCS was … Continue reading Notes – PRISM lab meeting, Chris
I won't be writing about every chapter of this book, but this is the first of my posts about books I'm reading, as I attempt to find some coherence in my reading which tends to involve being halfway through 10 books at the same time. Chapter 2, "The Movement Chauvanist", heavily features Dan Wolpert, whose … Continue reading The Performance Cortex chapter 1 – error detection, baseball bats and “wiffle balls”
During movement, a predictive signal with information on the consequences of an action is integrated with an afferent signal with actual sensory information triggered by the movement. This helps overcome neural delays and navigate noisy environments. Without brain stim, there are probably two main ways to alter the balance of these two signals, the combining … Continue reading Thoughts on sensory attenuation, body state estimation and whole vs part practice
I collected the data from the first participant for my pegboard task this week. It's a simple pilot study where we aim to investigate how sensory uncertainty affects motor learning during a fine motor control task. The participant simply has to fill holes on a pegboard with pegs, but one group wears a blindfold to … Continue reading Pegs.
