Arctic reindeer extend their visual range into the ultraviolet.
The Arctic has extreme seasonal changes in light levels and is proportionally UV-rich because of scattering of the shorter wavelengths and their reflection from snow and ice. Here we show that the cornea and lens in Arctic reindeer do not block all UV and that the retina responds electrophysiologically to these wavelengths. Both rod and cone photoreceptors respond to UV at low-intensity stimula...
متن کاملCan off-centre mesogen dipoles extend the biaxial nematic range?
We have investigated the possibility of extending the stability range of the biaxial nematic phase by adding an off-centre dipole of various strengths and orientations to elongated biaxial Gay-Berne (GB) mesogens yielding a relatively narrow biaxial nematic (Nbx) phase, and a smectic (Sbx) phase when dipole-less. The effect of dipoles is not easy to predict, and our previous investigations have...
متن کاملDisinhibition combines with excitation to extend the operating range of the OFF visual pathway in daylight.
Cone signals divide into parallel ON and OFF bipolar cell pathways, which respond to objects brighter or darker than the background and release glutamate onto the corresponding type of ganglion cell. It is assumed that ganglion cell excitatory responses are driven by these bipolar cell synapses. Here, we report an additional mechanism: OFF ganglion cells were driven in part by the removal of sy...
متن کاملSuperimposed Non Interfering Probes to extend the Phase Doppler Anemometry size range
In classical phase Doppler systems three detectors are commonly used to determine the particles size whatever, basically, this technique requires only two detectors. The third detector is in fact mainly used to overcome the 2 ambiguity on phase-shift measurements. In the present work an alternative solution is introduced which allows to keep the same accuracy and dynamic range of the size measu...
