A team of scientists has developed a way to see where and how memories are stored in the brain.
The team, led by Don Arnold and Richard Roberts of USC, engineered microscopic probes that light up synapses in a living neuron in real time by attaching fluorescent markers onto synaptic proteins — all without affecting the neuron’s ability to function.
The fluorescent markers allow scientists to see live excitatory and inhibitory synapses for the first time — and, importantly, how they change as new memories are formed.
The synapses appear as bright spots along dendrites (the branches of a neuron that transmit electrochemical signals).
As the brain processes new information,
