Re: Sound and how the brain reacts to it

... are converted into electrical signals and sent to the brain. What remains unexplained is how the weakest audible sounds are detected, since they excite vibrations below the thermal noise background in the ear. The answer may be active amplification. Previous experiments performed in vitro found ...

Blue light can excite EtBr absolutely. Many people knows. All the issues are ONLY about contrast.

no, I'm saying, that I doubt, whether will it excite (and especially how much), if you excite it with 500 nm

... the mechanism of Sybr dyes. The difference between excitation and emission wavelength of SyBrSafe is even smaller. So it is possible for EtBr to excite with storng 500 nm light and observe the emission of 600 nm with an amber filter to cut the 500 nm background.

UltraBright UV transilluminator

the question is, whether will you get emission in VIS, if will you excite in 500 nm, what I highly doubt about... Nonetheless, the maximum of emission is ~600nm, what makes difference only 100 nm and I don't know, how great would you see the yeallow (green ...
