Sensory Attenuation in Sport and Rehabilitation: Perspective from Research in Parkinson’s Disease

Years ago, I became interested in Parkinson’s disease. I had always been obsessed with sport, but from there emerged a fascination with how improving movement in both athletes and people with Parkinson’s might share the same principles. Kearney & Brittain (2021), Brain Sci. I didn’t set out to investigate this in our paper. Rather, we … Continue reading Sensory Attenuation in Sport and Rehabilitation: Perspective from Research in Parkinson’s Disease

Sensory consequences to bring about actions – where does it end?

Just to be a little provocative and take an idea beyond the domain it was birthed and intended for – what happens when a whole day is shaped by predicted sensory consequences and not just a momentary action? In predictive processing, a prediction itself acts as a motor command. This means a context, goal thought, … Continue reading Sensory consequences to bring about actions – where does it end?

Surfing Uncertainty chapter 4 – Prediction Action Machines

I have only just discovered this book (academic PDF link and purchase link), and I have only just read this chapter, but as well as loving reading every page of it, the author Andy Clark provides a really thorough account of predictive processing theory in the context of movement. The topic excites me because it … Continue reading Surfing Uncertainty chapter 4 – Prediction Action Machines

Thoughts on sensory attenuation, body state estimation and whole vs part practice

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

Papers of interest this week (courtesy of my supervisors): Functional connectivity of SII and cerebellum in sensory attenuation – fMRI and force-matching AI helps inform role of dopa cells in learning – predicted future rewards encoded as probability distribution, not single mean (which got me thinking back to this one) Somatosensory oscillations and tactile attention … Continue reading Briefly…
