Optimized sensors to study learning and memory

Scientists are working to understand how molecules send messages throughout the neuron, constantly working to develop high-resolution imaging techniques to visualize the activity and location of the molecules involved in the process. This team has developed new molecular biosensors, which helped them to visualize the activity of two signaling proteins crucial to synaptic plasticity. The results revealed signal spreading during structural plasticity of dendritic spines.
