- There is a network that controls hand movements.
- The brainstem is part of this network.
- The spinal cord is also part of the network.
- Researchers find connections between brainstem and spinal cord.
- Scientists study mice and human volunteers with simple tasks.
- They use brain scans to see activity during movement.
- The same regions are active in both species.
- The top spinal segments act as relay centers.
- This discovery may help people after stroke.

High-fat diet lets gut bacteria reach mouse brains
Emory University researchers found that a short high-fat diet can let live gut bacteria travel to the brain in mice. The bacteria moved along the vagus nerve; returning to a normal diet reduced this effect and researchers call for more study.
Brain activity guides social adaptation
A University of Zurich study explains adaptive mentalization—how quickly people infer others' thoughts and change behavior. Over 550 participants played rock-paper-scissors while researchers used fMRI and a computational model to link brain activity to adaptation.
Human intelligence arises from coordinated brain networks
Researchers used neuroimaging and two adult datasets to test the Network Neuroscience Theory. They found that general intelligence reflects system-level organization and coordination across large-scale brain networks, with implications for development, injury and artificial systems.
New research questions cause of hydrocephalus
A new study suggests hydrocephalus may result from the brain failing to absorb heartbeat pulses, not from simple fluid malabsorption. The authors point to the cerebral windkessel system and call for more imaging research and better shunt designs.
