Efficient auditory coding
Article Abstract:
The complete acoustic waveforms for natural sounds can be represented efficiently with a nonlinear model based on a population spike code. When the features are optimized for coding natural sounds or speech, they show striking similarities to time-domain cochlear filter estimates, have a frequency-bandwidth dependence similar to that of auditory nerve fibres and give greater coding efficiency than conventional signal representations.

Neural coding by correlation
Article Abstract:
The constraints imposed by interval correlations are likely to reduce the transmission of information. However correlations of intervals between signal pulses are capable of reducing low-frequency noise and thus increase the transfer of information.

Migratory neural crest-like cells form body pigmentation in a urochordate embryo
Article Abstract:
A description on a migratory cell population resembling neural crest cells in the ascidian urochordate Ecteinascidia turbinata is presented. The study concludes that migratory neural crest-like cells are present in the ascidian Ecteinascidia.
