Low-dimensional versus high-dimensional chaos in brain function – is it an and/or issue?
Márk Molnár · Behavioral and Brain Sciences · 2001
We discuss whether low-dimensional chaos and even nonlinear processes can be traced in the electrical activity of the brain. Experimental data show that the dimensional complexity of the EEG decreases during event-related potentials associated with cognitive effort. This probably represents increased nonlinear cooperation between different neural systems during sensory information processing.
