Reading our brain chemistry

Researchers at EPFL have developed a new device and analysis method that let doctors measure the neurochemicals in a patient’s brain. The Microsystems Laboratory 4 (LMIS4)’s system involves collecting microdroplets of cerebral fluid and analyzing them to obtain chemical data that can help doctors diagnose and treat neurodegenerative diseases._EPFL

A new robot mimics vertebrate motion

Based on X-ray videos, EPFL scientists have invented a new robot that mimics the way salamanders walk and swim with unprecedented detail: a tool for understanding the evolution of vertebrate locomotion._EPFL

The gates of serotonin

Serotonin is a major neurotransmitter, regulating mood, appetite, sleep, memory, learning, and other functions by binding to dedicated receptor proteins. Serotonin receptors have been researched for decades, but details about their structure and function are hard to come by. EPFL scientists have now made the first ever computer simulation of a notoriously elusive serotonin receptor that is involved in fast signal transmission in neurons and plays a central role in disorders such as schizophrenia, chemotherapy nausea, irritable bowel syndrome, anxiety, and seizures. The work is published in the journal Structure._EPFL
