Taken together, these findings lead the authors to hypothesize the existence of a hierarchical relationship between regions TE and 36, in which paired associations first established in the former region are propagated to the latter one. Here, area 36 represents the next level of a so-called feed forward hierarchy. detailed representations of objects commonly observed in the brain are attained not by buildup of representations in a single area, but by emergence of these representations in a hierarchically prior area and their subsequent transfer to the brain region that follows. There, they become sufficiently prevalent for the brain to register. The work also reveals that the brain activity involved in recreating visual stimuli emerges in a hierarchically lower brain area than previously thought. As a next step, the team hopes to further elucidate interactions between the various cortical microcircuits that operate in memory encoding. With the conjectured that these microcircuits are manipulated by a global brain network. Using the results of this latest study, he and colleagues are poised to further evaluate this assumption. It will also be important to weave the neuronal circuit mechanisms into a unified framework, and to examine the effects of learning on these circuit organizations. Equipped with their new view of cortical processing, the team also hopes to trace the causal chain of memory retrieval across different areas of the cortex. Recent advances in genetic tools allow us to do this. A better understanding of object representations from one area of the brain to the next will shed even greater light on elusive aspects of this hierarchical organ. #OrganicComputersInHyperspace #Brain #Mind #Thought #Consciousness #Insanity #TheImage
