Increased striatal coupling one week after ischemic stroke revealed by ultrafast functional MRI
Background: Network reorganization following ischemic stroke is thought to play a role in recovery. Although cortico-cortical reorganization is widely established, changes in interhemispheric striatal...

Ramping up cortical activity in early life sparks autism-like behaviors in mice
The findings add fuel to the long-running debate over how an imbalance in excitatory and inhibitory signaling contributes to the autism.

Tried this on a very technical fMRI manuscript with neuroscience applications. It warned me that neuroses outside its core expertise, but then proceeded to present an amazing analysis of the claims in the paper. Vastly superior to ChatGPT for example. I am impressed!
