  • (19) To minimize electronic noise and drift for detection of very small SPR signals, a mechanical light chopper was used for gated-signal detection, and a pulse height analyzer for noise rejection.
  • (20) We present a specific point process model that describes the scaling process and successfully replicates the observed responses to monaural and binaural stimulation of the three types of LSO units: slow choppers, fast choppers, and bimodal units.

Copper


Definition:

  • (n.) A common metal of a reddish color, both ductile and malleable, and very tenacious. It is one of the best conductors of heat and electricity. Symbol Cu. Atomic weight 63.3. It is one of the most useful metals in itself, and also in its alloys, brass and bronze.
