Modelling the brain from the bottom up; the Matlab auditory nervous system (MAP)

09. May 2017 um 16:00 Uhr

Raymond Meddis, University of Essex, Department of Psychology

Acoustics Research Institute of the Austrian Academy of Science, Wohllebengasse 12-14, 1040 Wien, Seminarraum

 

 

Abstract:

Thinking and knowing is often associated with the cortex but the cortex

cannot function without input from the sense organs and, in the case of

hearing, the computations that take place in the auditory brainstem. This

talk will describe a computer model in an advanced stage of construction

that emulates the auditory signal processing in the brainstem. The model

consists of an excitatory and inhibitory network of 30 different types of

known brain cells each with their own computational characteristics. The

output of the model is validated on a cell by cell basis by comparison

with physiological data. The model is mature enough to allow visualisation

of how the lower reaches of the auditory nervous system responds to simple

and complex sounds. It is offered as a downloadable toolbox for the

acoustics community to explore and improve.
