Abstract

Abstract Background Monitoring the activity and morphology of neuron-Astrocyte networks in culture is a powerful tool for studying dynamics, structure, and communication in neuron-Astrocyte networks independently or as a model of the sub-brain network. These cultures are known to produce stereotypical patterns of activity, e.g., highly synchronized network bursts resembling sleep or seizure states, thus it enables the exploration of behaviors that can relate to brain function and disease. High-resolution microscopy of calcium imaging combined with simultaneous electrical recording provides a comprehensive overview on the network's dynamics. This setup makes it possible to apply global perturbations of electrical and chemical stimulation on the cultures during the recording task and to record the effects on network activity on-line. Morphological changes in the cultures can be obtained to have a complete dataset for structure-function study of neuron-Astrocyte networks in vitro. Findings The 4 TB of data presented here was recorded and imaged as part of an accompanying study looking at in vitro structure-function of neuron-Astrocyte networks. Simultaneous optical (calcium imaging) and electrical (micro-electrode array) recordings lasted 5-12 minutes and included spontaneous activity recording, electrical and chemical stimulation of neuron-Astrocyte, and isolated astrocyte cultures. The data include activity recordings of 58 different cultures, with 1-2 regions of interest recorded for each culture. Production procedures, experimental protocols, and reuse options are included. The data have been suitable to reveal changes in the activity and morphology of the cultures and enabled observation and analysis of neuron-Astrocyte and isolated astrocyte culture behaviors under the applied perturbations. Conclusions Our dataset is sufficient to show significant changes in activity and morphology of neuron-Astrocyte networks in culture under the applied stimulations. More than 100 recordings of 58 different cultures give insight of the observation's significance and led to conclusions about astrocyte activity and neuron-Astrocyte network communication. Making it available here will allow others to test new tools for calcium imaging analysis and extracellular neuronal voltage recordings.
