Excitation conditions and threshold values Jar gain narrowing ill different conjugated polymers. Note that it is in some cases difficult to compare the values due to the different laser pulse duration used in the experiments. indicates the wavelength for excitation. is the pulse duration of the exciting laser pulse and A the area of the spot on the sample.

In electrical engineering terms, we can say that the operation of the brain and nervous system and the ordinary consciousness that results constitutes a high-gain, narrow-band filter dealing with the immediate physical present. This is obviously of high biological significance for our survival. The second dimension of time, which awareness can sometimes work with, is a filter with a much wider band, but its output is ordinarily quite low.
