How brain architecture relates to consciousness and abstract thought

Could lead to better ways to identify and treat brain diseases and to new deep-learning AI systems

Generated by human-blind automated procedures, this diagram depicts an oversimplified graphical model of the information representation flow from sensory inputs (bottom) to abstract representations (top) in human cortex. Bottom layer of the pyramid included a sample representative description of the 20th percentile of behavioral elements closest to sensory inputs, the next layer up includes a sample description of behavioral elements from the 20–40th percentile…with the top layer containing a sample description of the behavioral elements distributed deepest in the cortical network, at the structural pinnacle of cognition.

Ever wonder how your brain creates your thoughts, based on everything that’s happening around you (and within you), and where these thoughts are actually located in the brain?
UMass Amherst computational neuroscientist Hava Siegelmann has, and she created a geometry-based method for doing just that. Her team did a massive data analysis of 20 years of functional magnetic resonance imaging (fMRI) data from tens of thousands of… read more
