The Effect of Speech Masking on the Human Subcortical Response to Continuous Speech https://t.co/aqVOCMACH8 Lovely work by @mel_polonenko and @maddox_lab

Auditory masking—the interference of the encoding and processing of an acoustic stimulus imposed by one or more competing stimuli—is nearly omnipresent in daily life and presents a critical barrier...

🧵In a meta-analysis of randomized controlled trials that enrolled patients with acute ischemic stroke beyond 4.5 hours of time last known well, administration of thrombolysis (compared with placebo) led to a higher odds of a good functional outcome despite a higher odds of sICH.

Does expert use of IFCN spike criteria improve IRR? This study says no—not by itself. But AUC was high (0.91), and IRR improved with a threshold of 5 in the consensus dataset. Only 2/9 experts watched the training videos. https://t.co/OcI13jNHt1

If you can accept the data on vaccines, maybe you could consider accepting the data on social inequalities (and become a leftist) #jointhefold #thedataareclear
Why do so many people here (Americans in particular) assume I am a Democrat or a Leftist? I am neither I just think vaccines don't cause autism. How does that make me a leftist ? 🤷♂️

Naturalistic audiovisual illusions reveal the cortical sites involved in the multisensory processing of speech https://t.co/B1ilXO7O2N by @pierre_vanmedge et al; "higher order sensory and associative areas, rather than early sensory cortices, are key loci for illusory perception"

We designed innovative audiovisual speech illusions and used intracranial EEG to localize the cortical sites of multisensory speech processing. Whereas sites that tracked the auditory and visual...
