Recruitment of Agranular Areas Key to Processing in Brain?
Graeme E. Smith, GreySmith Institute of Advanced Studies
The cortex has been classified as having several types of Micro-Anatomy. Isocortical Tissues have the full 6 layers or laminae, Agranular Tissues have similar anatomy but with attenuated or missing 4th layers, and Allocortical Tissues have 3 or less layers of tissue. It has been suggested that the Granular layer (Layer 4) is connected to the thalamus at least in the neocortes, and that therefore Isocortical areas are primarily concerned with processing sensory data. It has further been suggested that Agranular tissues might form Fodor-like modules and be recruited indirectly or directly by the attention system. In this article I present the hypothesis that recruitment of modules by the attention system, is the primary mechanism for guiding processing blurring the distinction between Action and Process.
