Contents of visual predictions oscillate at alpha frequencies
Predictions of future events have a major impact on how we process sensory signals. However, it remains unclear how the brain keeps predictions online in anticipation of future inputs. Here, we combin...

@dotproduct.bsky.social's first first author paper is finally out in @sfnjournals.bsky.social! Her findings show that content-specific predictions fluctuate with alpha frequencies, suggesting a more specific role for alpha oscillations than we may have thought. With @jhaarsma.bsky.social. 🧠🟦 🧠🤖

Farage can now be easily boxed in to a corner where his only ‘defence’ becomes: “Yes I spouted Kremlin propaganda & Putin worship but, unlike Nathan Gill, I didn’t need bribes to do it.”
It is, once again, a question of whether interviewers have the temerity to shut down his whining obfuscations.

How do changes in context influence how we organize our memories in time?
Faster contextual changes are associated with faster drift in hippocampal activity and reduced temporal clustering in recalled memories.
