     In the midbrain defensive circuit, the decision to escape is computed by an unreliable synaptic connection that thresholds threat information integrated in the medial superior colliculus, and controls activation of dorsal periaqueductal grey neurons.

    Specular scattering of atoms of helium gas flowing through atomically flat, two-dimensional channels results in frictionless gas flow, which is much faster than expected assuming purely diffusive scattering.

    A subset of synaptic proteins are cumulatively phosphorylated during wakefulness and dephosphorylated during sleep, in accordance with sleep need; this may represent a common mechanism underlying regulation of both synaptic homeostasis and sleep–wake homeostasis.
