Shining Light Deep into the Brain

To map the inner workings of the living brain, scientists have long employed various types of brain probes, beginning with simple electrical wires and...
prefrontal cortex

Traffic Light in the Brain

Whether the brain responds to an external stimulus or not depends significantly on the balance between areas of excitation and inhibition in the prefrontal...

Tailored Carbon Could Help Treating Neurological Diseases

Tomi Laurila's research topic has many quirky names."Nanodiamond, nanohorn, nano-onion...," lists off the Aalto University Professor, recounting the many nano-shapes of carbon. Laurila is...
cerebral cortex

Neurons Form Synapse Clusters

The cerebral cortex resembles a vast switchboard. Countless lines carrying information about the environment, for example from the sensory organs, converge in the cerebral...
