Tutorial for WCCI 2012
This tutorial will present material about the brain and mind (brain-mind) from the viewpoints of six disciplines --- biology, neuroscience, psychology (including cognitive science), computer science, electrical engineering, and mathematics. However, any person with a undergraduate degree should be able to understand much of the material presented. An overarching model about how the brain-mind works will be presented backed by evidence from the six disciplines. The model proposes six necessary "chunks" for the brain-mind picture: development, architecture, area, space, time and modulation.
The development chunk takes into account how biological cells autonomously migrate, grow, connect, adapt, and interact with one another need for us to understand not only how the brain works but also how the mind emerges.
The architecture chunk describes how the biological development gives rise to connections and interactions among cerebral areas to give rise to the brain that neuroscience studies. It explains organization principles for the functions of perception, cognition, motivation and behavior that psychology studies. The architecture also outlines how the brain leans concepts, meanings, and procedures from the physical world; deals with multiple objects in complex backgrounds; self-generates intent; reasons with intent; and integrates multiple sensory and motor modalities. These are subjects that computer science deals with but with great difficulties.
The area chunk addresses the issue of feature development and areal representation and how the role of each neuron emerges from interactions among cells in each area. The representational optimality will be discussed, in terms of the limited neuronal resource and the limited learning experience. These issues are central for neural networks that electrical engineering and other disciplines deal with.
The space chunk clarifies how the brain network deals with spatial information, such as bottom-up and top-down attention (e.g., to deal with multiple objects in complex backgrounds), desired invariance (location invariance and type invariance), desired specificity (e.g., object type specificity and object location specificity), abstract concepts, and meanings. All the six disciplines are interested in these issues.
The time chunk addresses how the brain uses its intrinsic spatial mechanisms to deals with time, without dedicated temporal components (e.g., silence detector or key frame detector), such as contexts of spatiotemporal events while having desired properties for time warping, time duration, temporal attention, and emergence of behaviors for any temporal length and any temporal subsets. Again, all the six disciplines are interested in these issues.
The modulation chunk clarifies the brain’s intrinsic motivational system so that the brain not only performs signal processing, but also be sensible to punishment, regards, and novelty. We will discuss the serotonin system and the dopamine system, but only touch on the acetylcholine system and the norepinephrine system. In addition to the six disciplines, medicine, social science, political sciences, and philosophy are interested in such subjects.The theory, mechanisms and algorithms are presented with related experimental results.
