These images represent the firing of a ‘place’ cell as an animal explores its environment. Left: While the animal explores the environment, spikes are recorded from many different cells, with each circle representing the firing of a cell in the brain. Advanced sorting algorithms identify which spikes came from the place cell, shown in red. Techniques used to capture these data are at the cutting edge of neuroscience research and are central to the work of many SCGB investigators. Right: A place cell fires more frequently when the animal reaches a particular location in its round environment; warmer colors indicate increased firing. Images adapted from Aronov D. and D. W.
