Hierarchy of approximations involved in simplification of microscopic theories, 
from sub-cellural to the whole brain level, is presented. A new approximation to 
neural dynamics is described, leading to a Platonic-like model of mind based on 
psychological spaces. Objects and events in these spaces correspond to quasi-stable 
states of brain dynamics and may be interpreted from psychological point of view. 
Platonic model bridges the gap between neurosciences and psychological sciences. 
Static and dynamic versions of this model are outlined and Feature Space Mapping, 
a neurofuzzy realization of the static version of Platonic model, described. 
Categorization experiments with human subjects are analyzed from the neurodynamical 
and Platonic model points of view.
