Topic: radial eight-arm maze

The spatial coding in the hippocampus (HPC) and its emergence during learning is well studied, but it is still unclear how the spatial information in the medial prefrontal cortex(mPFC) is changing between different learning stages. We recorded multiple unit activity using a combination of 24 movable tetrodes for the HPC and a Neuropixels silicon probe with 384 channels for the mPFC. We monitored the formation of spatial representations in both regions while the rat performed a spatial memory task on the radial eight-arm maze. The animal started in the center of the 8-arm maze and needed to loc
