Multimodal evaluation of network activity and optogenetic interventions in human hippocampal slices This paper demonstrated for the first time that optogenetic tools can be used to modulate network activity in human brain slices, bridging the long-lasting gap between human and animal studies. The MaxOne Single-Well High-Density Microelectrode (HD-MEA) System was used to record the spontaneous and light-evoked activity of human hippocampal slices.
