Researchers at Chalmers University of Technology and Gothenburg University in Sweden have achieved something long thought almost impossible – counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. […] The ability to measure the activity and quantity of glutamate in brain cells has been long sought-after among researchers. […] The new finding, that glutamate-based communication is regulated by the quantity of glutamate released from synaptic vesicles, begs the question of what happens to this regulation in brain diseases thought to be linked to glutamate, for example epilepsy.”
