Squirrel neuron structure changes during hibernation

Caption

Representative visuals of neuron structure in a key brain area for processing visual information in squirrels. Top: Neurons from nonhibernating squirrels. Middle: Neurons in squirrels during the deep sleep (Torpor) phase of hibernation. Bottom: Neurons in squirrels during arousal from Torpor, another phase of hibernation. Neurons undergo rapid structural changes during Torpor that are reversed during arousal compared to nonhibernating squirrels.
