The most commonly used readout for eye function in fruit flies is the electroretinogram (ERG). While ERGs are applied to study phototransduction, they also constitute a robust assay to assess neuronal communication between photoreceptors and second-order brain neurons. Using glass electrodes placed

This study aimed to create a versatile and reproducible in vitro model of a human motor unit with functional neuromuscular junctions (NMJs). Therefore, human induced pluripotent stem cell (hiPSC)-derived motor neurons and human primary mesoangioblast (MAB)-derived myotubes were co-cultured in
