THE MIND WORK LIKE A COMPUTER CPU
EXAMPLE MIND HAVE WIRED VEIN LIKE WIRE SO TO MUCH QUESTION ABOUT YOU MIND SO THE QUESTION AND THEIR ANSWER HERE SCROLL DOWN
How and why do humans think and act in the ways that we do? To answer this question, Dr Paul Badcock and his colleagues have recently proposed a theory of the human brain that combines evidence from evolutionary and developmental psychology, neuroscience, and biology. This theory posits that the human brain is a complex adaptive system, composed of relatively specialised and domain-general structures that work in tandem to generate adaptive responses to the environment. Arguably, their Hierarchically Mechanistic Mind (HMM) model brings us closer to a comprehensive understanding of the brain. The desire to understand the greatest enigma of all – our own minds – has been the driving force behind many scientific endeavours, leading to the development of theories and experiments aimed at explaining the mechanics of being human. Human thoughts, feelings, and behaviours are rooted in the brain, where a complex network of cells receives information from the internal and external environment, transforming this information into our experience of ourselves, the world around us, and our relationships with it. It goes without saying that how this happens is still being explored. Relative to those before, the 21st century has borne witness to tremendous advances in our understanding of the brain. Research is still ongoing, of course, albeit now more ecumenical than ever – bringing together fields that have long been divided. At the cutting edge of progress in synthetic, interdisciplinary research, the group led by Dr Paul Badcock has recently proposed a model of the brain that synthesises major paradigms from psychology, neuroscience, and biology to explain why and how we think and act in the ways that we do. Their hypothesis, called the Hierarchically Mechanistic Mind (HMM), combines two established claims. The first claim, formulated by Dr Badcock’s colleague, Professor Karl Friston, postulates that the human brain is a hierarchical ‘prediction machine’ that strives to improve its model of the world by generating adaptive cycles of perception and action that operate synergistically to reduce our uncertainty about the environment. The second claim, based on Tinbergen’s famous four questions in ethology, proposes that to understand human thoughts andbehaviours, hypotheses must be developed and tested across multiple levels of analysis in psychological science. In other words, researchers seeking to explain psychological traits should endeavour to understand why a given trait might be adaptive, along with how it emerges from the dynamic interplay between evolutionary, developmental, and real-time mechanistic processes. The way the brain is wired The HMM is built upon the idea that the brain is composed of distinct components that have different functions and that exchange information in a hierarchical, integrated fashion. For example, there areparts of the brain that are responsible for processing sensory stimuli and controlling particular types of movement, while other parts of the brain, like the prefrontal cortex, integrate and act upon information processed elsewhere to generate executive decisions. Smaller, more specialised elements are encapsulated into larger elements for combined functionality, acting in a kind of hierarchy that creates dependencies between structures. This architecture is characterised by two types of processing: specialised functional processing that occurs over a short distance, within a dense, focused neural region; combined with a global, functional integration that occurs over longer distances between structures. In other words, our thoughts, feelings, and actionsare determined by the complex, long-distance integration of localised processes, which are created by specialised populations of cells connected to other regions that each perform different functions. Evidence for this architecture The idea that the brain is built of distinct but collaborating components has long been recognised and is backed by extensive empirical support. Reports summarising results of neuroimaging data have provided clear support for the continuum between domain-specific and domain-general processes in the brain, demonstrating that individual neural regions perform distinct functions and interact with different regions in different contexts, depending on the demands of the task at hand. Further research has shown that a neural network can be represented as a collection of nodes and edges, which stand for brain structures and their connections. Structural and functional connectivity studies have found that each brain structure forms part of a distinct network of hierarchical connections with other neural structures, which allows the brain to optimise the delicate balance between local, specialised processing and global brain function. Notably, animal studies have also demonstrated that a hierarchical structure is a characteristic feature of the mammalian brain. THANK YOU FOR VIEW THIS ARTICLE
