iGlu3Fast and iGlu3Slow, improved fluorescent reporters for detection of spontaneous glutamate activity in the brain

The paper introduces two improved fluorescent glutamate sensors, iGlu3Fast and iGlu3Slow, with distinct kinetic properties for imaging glutamate activity in the brain.

The vesicular release probability sets the strength of individual Schaffer collateral synapses

The paper measures vesicular release probability at individual synapses and finds it determines synaptic strength rather than vesicle number or content.

Single synapse indicators of impaired glutamate clearance derived from fast iGluu imaging of cortical afferents in the striatum of normal and Huntington (Q175) mice

The paper uses iGluu imaging to analyze glutamate clearance at single synapses in Huntington's disease mice, finding impaired uptake and release in affected synapses.

Ultrafast glutamate sensors resolve high-frequency release at Schaffer collateral synapses

The paper develops ultrafast glutamate sensors iGluu and iGluf to study high-frequency synaptic transmission, revealing presynaptic frequency-dependent filtering of spike trains.
