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?
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
As we interact with the world around us, we process loads of sensory information across different modalities. But this isn't done passively – the overwhelming consensus is that we proactively interact with the environment, using priors or predictions about the world and about sensory consequences to optimise and streamline perception and action. For instance, when … Continue reading Commentary: Forms of prediction in the nervous system – Teufel and Fletcher
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
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…
