Robustness of Cognitive processes

10:30 am
I was browsing through the TOC alert emails and found the following paper
The nature of the memory trace and its neurocomputational implications
by: P de Vries, K van Slochteren
Journal of Computational Neuroscience, Vol. 25, No. 1. (2008), pp. 188-202.

The abstract was stating exactly what I have thought about 10 years ago. I am sure the idea is generally known to many people, but this was stated as I liked:
The brain processes underlying cognitive tasks must be very robust. Disruptions such as the destruction of large numbers of neurons, or the impact of alcohol and lack of sleep do not have negative effects except when they occur in an extreme form. This robustness implies that the parameters determining the functioning of networks of individual neurons must have large ranges or there must exist stabilizing mechanisms that keep the functioning of a network within narrow bounds...


The paper builds a high level model of neural assemblies.
