Independent Component Analysis (ICA) proves to be useful in the analysis of neural activity, as it allows for identification distinct sources activity. Applied measurements registered a controlled setting and under exposure an external stimulus, can facilitate impact stimulus on those sources. The link between given source verified by classifier that is able "predict" condition signal was under, solely based components. However, ICA's assumption about statistical independence often...

Computational modeling of biological neurons allows for exploration many parameter combinations and various types neuronal activity, without requiring a prohibitively large number ldquowetrdquo experiments.
