Functional neuroanatomy of the centrál auditory systém is more complicated than the functional neuroana- tomy of the visual systém. Neuronal and mental representations of the acoustic information are formed by extraction of its statistical properties and by construction of acoustic objects. The mapping of the acoustic cor- tex discovered root, core, belt and parabelt zones and their projections to other cortical areas. The acoustic systems WHAT, WHERE and WHEN are shortly described. Central acoustic disorders are word deafness, acoustic agnosia and cortical deafness.
