Some of the least understood phenomena in the brain emerge from interactions between local and global brain states, yet representing their joint activity is a considerable computational challenge. As ...

⚛️🧠 Why might neuroscience need quantum computing? Not because the brain is "quantum", but because interactions between local & global dynamics create an enormous representational challenge. Our piece in @natrevneuro.nature.com argues quantum computers could open a new path: doi.org/10.1038/s415...

What mechanisms underlie health benefits of social interaction? @ryssamoffat.bsky.social @introspection.bsky.social @escross.bsky.social show that neural synchrony during a creative drawing program decreases in intergenerational dyads & increases in same-generation @plosbiology.org 🧪 plos.io/4gbafyY
An intergenerational dyad draws together. Without prompts and through collaboration, they create shared drawing. While they draw, their brain activity is recorded using mobile sensors and their body movements are tracked using video-based motion capture. Photograph captured by Ryssa Moffat. The participants depicted in this photograph have provided written consent for their likeness to be published alongside open-access online research outputs.
