This AVSP Visionaries interview is with Emeritus Professor Denis Burnham youtube.com/@AVSPVisionari… Denis was an early pioneer of AV speech perception research. We learned a lot doing this interview. Please view this one - as we need view numbers for the go ahead on the others!

Some quick ones: Subthalamic nucleus neurons encode syllable sequence and phonetic characteristics during speech pubmed.ncbi.nlm.nih.gov/39470420/ Does pre-speech auditory modulation reflect processes related to feedback monitoring or speech movement planning? pubmed.ncbi.nlm.nih.gov/39461704/


Differential modulations of theta & beta oscillations by AV congruency in letter-speech sound integration onlinelibrary.wiley.com/doi/10.1111/ej… Looked at cortical oscillations for AV in/congruency at oscillatory frequencies bands during a letter-speech priming task & analysed power & phase


Sub-cone visual resolution by active, adaptive sampling in the human foveola elifesciences.org/articles/98648 "The surprising result is that ocular drift is systematic - causing the object to move to the center of the cone mosaic over the course of each perceptual trial"
