Synantocytes may generate and determine the space structure of the brain
Bernhard J. Mitterauer
How does the brain represent space? Is this representation entirely the result of learning from experience? In his Critique of Pure Reason, Immanuel Kant argued that there must be certain ”a priori conditions” of cognition, which cannot be derived from experience but must instead be given prior to it. Recently, two groups have conducted experiments on rat pups and interpreted their results in a Kantian view of space (Langston et al, 2010; Willis et al, 2010).
In both studies, the researchers placed electrodes in the hippocampal formation of freely moving 14-

According to the great physicist Smolin (1997), space is an aspect of temporal relations and events do not happen within a superposed space or environment. Since synantocytes are able to register the information flux of all relevant cell systems of the brain, they may generate a relational structure via their processes embodying a specific subjective space. From a brainphilosophical point of view, each subjective space generated by a synantocyte represents a subjective reality. Since synantocytes comprise 10 percent of all cell types of the brain (Butt et al, 2005), our brain may be composed of very many realities that may determine our subjective view of the subjects and objects in the environment.
In addition, the capability of synantocytes to regenerate damaged cells and to maintain the equilibrium of the extracellular space indicates that synantocytes generate and control distinct microdomains of space generation within the brain. For the realization of an inner space structure in the environment, the brain is equipped with neurons specialized in perceiving and monitoring the geometrical variables necessary for space recognition. This procedure is based on movement.
The experiments shortly discussed represent a typical case of an overinterpretation, especially by not referring to glia. At least from the perspective of a gliophilosophy -
