- Innovative 3D-printed implants and bioluminescent tools transform sensory process studies ()
A sensory process such as pain is no ordinary phenomenon-;it’s a symphony of neural and vascular interactions orchestrated by the brain and spinal cord. Attempting to dissect this symphony by focusing on a single region is like trying to understand a complex melody by listening to just one instrument. It’s incomplete, potentially misleading, and may […]

- First Complete Map of a Fly Brain Has Uncanny Similarities to AI Neural Networks ()
To most humans, a fruit fly larva doesn’t look like much: a pale, wriggling, rice grain-shaped maggot, just a few millimeters in length. Yet, in their own way, fly larvae lead rich and interesting lives full of sensory inputs, social behaviors, and learning. If you’ve ever doubted that a lot goes on inside a maggot’s […]
