Pupillary light reflex can be inhibited by multisensory signals

Multisensory integration has been recently shown to produce a larger pupil size than unisensory constituents. Superior colliculus (SC), an important laminar nucleus in the midbrain, not only engages in spatial attention and ...

Oscillation

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in physical systems but also in biological systems and in human society.
