This study measures the voltage-to-Ca2+ transfer function in hippocampal CA2 pyramidal neurons during behavior and develops a biophysics-inspired model to predict Ca2+ signals from voltage waveforms.

This study maps dendritic membrane potential dynamics in CA1 neurons during behavior, showing dendritic spikes are driven by back-propagating action potentials and influence spiking outputs and plasticity.

Luminos is an open-source MATLAB library for bidirectional microscopy that enables precise synchronization of stimulation, imaging, and experimental parameters.

The paper investigates dendritic excitations in CA1 pyramidal neurons, showing how locally generated Na+ spikes drive history-dependent spike back-propagation and influence associative plasticity.

This study uses live-cell imaging to show that 10 Hz electrical stimulation maximizes Arc transcription and correlates with calcium transients, but calcium alone does not fully explain Arc induction.

This study tracks synaptic changes in the hippocampus during fear memory formation and extinction, showing synaptogenesis and synapse modification between CA3 and CA1 engram cells.

The paper uses a genetically-encoded RNA indicator to visualize Arc mRNA dynamics in live animals during memory formation and retrieval, revealing rapid turnover in hippocampal neurons and stable expression in retrosplenial cortex neurons.
