The paper introduces PinkyCaMP, a new red fluorescent calcium sensor with improved brightness, photostability, and compatibility with optogenetics and neurotransmitter imaging.

This study uses human brain assembloids to show serotonergic innervation influences cortical progenitor states and proliferation during development.

This study identifies behavioral and cellular phenotypes in NEX-Cre mice, challenging their previous characterization as normal and highlighting variability in transgenic models.

This study demonstrates that the fluorescence lifetime of sDarken, a serotonin biosensor, decreases with serotonin concentration, offering a more reliable method for measuring serotonin dynamics.

This study investigates the role of serotonergic input to dorsal CA1 in mnemonic functions and finds that serotonin modulates spatial memory acquisition but not other behaviors.

The paper introduces sDarken, a new family of genetically encoded serotonin sensors, demonstrating their effectiveness in imaging serotonin dynamics with high resolution.

The paper demonstrates polarization sensitivity in GPCR-based neurotransmitter sensors and introduces an optical device to mitigate orientation bias in two-photon imaging.
