A drug from resin to combat epileptic seizures

New molecules, developed by researchers at Linköping University, have promising properties as possible drugs against epilepsy. A study published in the journal Epilepsia shows that several of the molecules have antiseizure effects.

Molecular physiology of voltage-gated ion channels.

Molecular physiology of voltage-gated ion channels

Voltage-gated ion channels are key players in all biological systems where they generate and modulate for instance the nervous impulse and pacemaker activity in the heart and the brain.
