The arrow of time is the "one-way direction" or "asymmetry" of time. The thermodynamic arrow of time is provided by the second law of thermodynamics, which says that in an isolated system, entropy tends to increase with time. Entropy can be thought of as a measure of microscopic disorder; thus the second law implies that time is asymmetrical ...
The simplest form of a unidirectional network is a modified, fiber-optic network link, with send and receive transceivers removed or disconnected for one direction, and any link failure protection mechanisms disabled. Some commercial products rely on this basic design, but add other software functionality that provides applications with an ...
Four of the cranial nerves serve the eye directly: one sensory and three motor nerves. The optic nerve is sensory and crosses the midline in the optic chiasm. The oculomotor nerve, trochlear nerve, and abducens nerve are motor nerves that control one or more of the eye muscles. The oculomotor nerve crosses the midline before leaving the central ...
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...
This figure shows nerve activity associated with rotational-induced physiologic nystagmus and spontaneous nystagmus resulting from a lesion of one labyrinth. Thin straight arrows show direction of slow components, thick straight arrows show direction of fast components, and curved arrows show direction of endolymph flow in the horizontal semicircular canals.
The inability to perceive motion is called akinetopsia and it may be caused by a lesion to cortical area V5 in the extrastriate cortex. Neuropsychological studies of a patient who could not see motion, seeing the world in a series of static "frames" instead, suggested that visual area V5 in humans [1] is homologous to motion processing area V5/MT in primates.

The principles of grouping (or Gestalt laws of grouping) are a set of principles in psychology, first proposed by Gestalt psychologists to account for the observation that humans naturally perceive objects as organized patterns and objects, a principle known as Prägnanz. Gestalt psychologists argued that these principles exist because the mind ...
