Neurons in the suprachiasmatic nucleus (SCN) function as part of a central timing circuit that drives daily changes in our behaviour and underlying physiology. We have a good conceptual ...

A great deal is known about mechanisms underlying circadian oscillations in the SCN 2, as well as circuits that control the states of sleep and waking 3,4. However, the manner in which these two ...

Deep-brain imaging in awake mice reveals how light resets the circadian clock by activating complex SCN neuron networks.
