The minnie_activity_12color image presents a selection of more than 1,000 brain cells from the 120,000 neurons and glial cells reconstructed in the MICrONS project. Each neuron is rendered in a distinct color to emphasize its individual structure. The glowing elements in the image correspond to the colored neurons.
