Line Plot from Scientific Research

Left: bidirectional theta sweeps when the animal runs along a straight trajectory with fixed head direction (the dark line). Blue to purple dots represent the internal direction (the bump center) across 1-s simulation. More purple dots represent higher peak firing rate of the activity bump. Right: polar histogram of the offset angle of the internal direction relative to the head axis over time. Note that the cluster around the peak of internal direction may occur because the activity bump requires some time to change direction, during which its speed reduces to zero before increasing again.
