Neural Field Dynamics With Local And Global Connectivity And Time Delay

February 16, 2009 at 2:00 pm Leave a comment

The human brain shows characteristic spectral features and irregular network activations while being at rest.

Recent computational research has explained the composition of the activated brain networks on the basis of the brain’s anatomical large scale connectivity and the time delays occurring due to signal transmission. However, the characteristic power law present in the frequency spectrum of the brain dynamics has not been accounted for.

In the current article, we show mathematically and computationally that this behaviour is a generic feature resulting from local connections rather than the large scale connectivity responsible for the rest state network selection.

Philosophical Transactions A

Each issue of Philosophical Transactions A is devoted to a specific area of the mathematical, physical and engineering sciences. This area will define a research frontier that is advancing rapidly, often bridging traditional disciplines.

Philosophical Transactions A is essential reading for mathematicians, physicists, engineers and other physical scientists. Find out more about the journal.
