The paper develops high-density transparent graphene electrodes to record neural activity from deeper cortical layers and decodes calcium activity from surface potentials using dimensionality reduction and neural networks.

The paper introduces E-Cannula, a tool for simultaneous electrical and optical recording in the hippocampus, revealing anatomical diversity in sharp-wave ripples and their association with distinct cell assemblies.

The paper demonstrates functional connectivity between human cortical organoids and mouse visual cortex using transparent graphene microelectrodes and two-photon imaging.

This study decodes large-scale cortical activity from local surface potentials using a recurrent neural network, showing that surface potentials contain rich information about neural activity across multiple regions.
