The task required the discrimination of two light signal durations (i.e. short- vs. long-latency signals) in order to obtain a food pellet in a trial (Fig. 5a).
Interestingly, visual discrimination of point-light motion of two interacting agents is worse when the two actions are desynchronized [24].
These include water-based liquid scintillators and fast photo-sensors and light concentrators to allow discrimination between flashes of light separated by a few hundred picoseconds – 10 times better than achieved by today's photomultiplier tubes.
Apparently to improve the discrimination of longer-wavelength light (yellow through red) by stomatopods, evolution has added colored filters between the successive tiers of some classes of rhabdoms.
Spectral discrimination of the detected light was, therefore, achieved using a set of five narrow-band filters centred at 1212, 1240, 1272, 1304 and 1332 nm (OD3 blocking, 20 nm FWHM; Omega Optical, Brattleboro, VT, USA) mounted on a motorised filter wheel in front of the detector.
As with our previous work (Patterson et al, 1990; Niedre et al, 2002a, 2002b; Niedre et al, 2003), we chose to use a set of NIR band-pass filters for spectral discrimination of the detected light rather than a monochromator (Hirano et al, 2002), since it allowed for maximum optical throughput and minimised the distance between the source and detector.
The protesters began marching through the nation's capital to call for justice and decry racial discrimination in light of recent deaths of black men at the hands of the police.
We develop a quantum learning scheme for binary discrimination of coherent states of light.
A clever solution to this dilemma is to circumvent the complexities of color processing and focus on the discrimination of different wavelengths of light (radiation).
This suggests that adults have increased discrimination of long wavelengths of light - an ability usually afforded by additional spectrally-distinct LWS opsins [ 30, 31], which we propose is a function of the A180 and S180 upregulation only observed in adults.
