hpIs675 [rgef-1p::GCaMP6s::3xNLS::mNeptune + lin-15(+)]. Worms express GCaMP6s and mNeptune in all neuronal nuclei. Pan-neuronal imaging strain; suitable for rapid whole-brain imaging due to brightness, good signal to noise ratio, and relative resistance to photo-bleaching. Reference: Susoy V, et al.
