How hibernation influences a visual brain area in squirrels

Understanding how hibernation affects neurons sheds light on how neurons adapt to changing states and can inform treatment strategies for conditions in which neurons are damaged or impaired. In a new JNeurosci paper, researchers led by Hendrikje Nienborg, from the National Eye Institute, used squirrels to assess how hibernation alters neuron structure in a brain area that responds to visual information from the eyes. Why focus on this visual brain area?
