The paper shows that MRS-measured Glutamate and GABA levels in awake mice correlate with excitatory and inhibitory neural activities during stimulation and in a Dravet syndrome model.

This study tracks tau fibrillogenesis and microglial phagocytosis of neurons in a living tauopathy model, showing that microglia engulf tangle-bearing neurons and that TSPO ligands can reduce this process.
