Common ground for action-perception coupling and its consequences for speech processing

February/09/2017 @ 11:00 - 12:30

Common ground for action-perception coupling and its consequences for speech processing by Sonja A. Kotz (Dept. of Neuropsychology and Psychopharmacology, Maastricht University, The Netherlands & Dept. of Neuropsychology, Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, Germany)

While the role of forward models in predicting sensory consequences of action is well anchored in a cortico-cerebellar interface, it is an open question whether this interface is action specific or extends to perceptual consequences of sensory input (e.g. Knolle et al., 2012; 2013 a&b). Considering the functional relevance of a temporo-cerebellar-thalamo-cortical circuitry that aligns with well known cerebellar-thalamo-cortical connectivity patterns, one may consider that cerebellar computations apply similarly to incoming information coding action, sensation, or even higher level cognition such as speech and language (e.g. Ramnani, 2006; Kotz & Schwartze, 2010, 2016): (i) they simulate cortical information processing and (ii) cerebellar-thalamic output may provide a possible source for internally generated cortical activity that predicts the outcome of information processing in cortical target areas (Knolle et al., 2012; Schwartze & Kotz, 2013). I will discuss new empirical and patient evidence (motor-auditory coupling and auditory only) in support of these considerations and present an extended cortico-subcortical framework encompassing action-perception coupling, perception, and multimodal speech.
