Measuring neural activity in moving humans has been a longstanding challenge in neuroscience, which limits what we know about our navigational neural codes. Leveraging mobile EEG and motion capture, Griffiths et al. overcome this challenge to elucidate neural representations of direction and highlight key cross-species similarities.

AbstractDecades of theoretical and empirical work have suggested the hippocampus instantiates some form of a cognitive map, yet tests of competing theories have been limited in scope and largely qualitative in nature. Here, we develop a novel framework to benchmark model predictions against observed neuronal population dynamics as animals navigate a series of geometrically distinct environments.
