- Title
- A continuum model of the mammalian alpha rhythm
- Author(s)
- Liley, David T. J.
- Abstract
- A continuum model is formulated in which neocortex is considered to be a continuous infinite one-dimensional chain of excitatory and inhibitory neurons interacting by way of isotropic short (intra-cortical) and long (cortico-cortical) fibres. Numerical solutions of the linearised equations reveal the presence of spatially weakly damped traveling waves at or near the frequencies of mammalian alpha (8-13 Hz). Biasing the excitatory cell population has a dominant effect in determining temporo-spatial damping of traveling wave solutions, whereas applying bias to the inhibitory cell population has a dominant effect in specifying the corresponding temporo-spatial frequencies.
