Too much of a good thing? How Rab39 Puts the Brakes on Synaptic Autophagy

Abstract: Presynaptic terminals can be located far from the neuronal cell body and are thought to independently regulate protein and organelle turnover. Autophagy is a critical process for maintaining proteostasis, and its synaptic dysregulation is associated with neurodegenerative diseases. We report a soma-centered mechanism that regulates autophagy-controlled protein turnover at distant presynaptic terminals in Drosophila. […]

Cell-type specific voltage imaging of neural spiking, oscillations, waves, and memory dynamics

Abstract: Fluorescent genetically encoded voltage-indicators report the membrane voltages of targeted cell-types. Recent advances in the development of these indicators have enabled optical voltage-imaging experiments capturing the spiking dynamics of up to 3 neuron classes at once in the brains of behaving mammals. We recently used this capability to uncover a new form of interaction between an […]
