Brain amazes me. It is the most complex organ. I find the study of brain fascinating. One of the amazing things of the brain is its ability to create patterns. The proof that the brain can create patterns is given by Pavlov’s experiments. The dog was receiving its food at the sound of a bell. After a while the sound of the bell made dogs produce saliva without seeing the food. The stimulus was producing a response.(Fredholm, 2008)
Brain cells (neurons) communicate with each other through their synapses. (Synapse [sinapsis] is a Greek word meaning union or “fasten together”)
The above picture is from (AHRW,1997).
The brain creates paths. The most travelled paths in the brain are those that their synapses are active and well established. The harder these chemical bonds are the harder it is to change the path of a given pattern or thought or habit.
Brain researchers have discovered that when we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks. It turns out that unless we continue to learn new things, which challenges our brains to create new pathways, they literally begin to atrophy, which may result in demenia, Alzheimer’s and other brain diseases. (RAE-DUPREE, 2008)
Why our brain choose to use only certain types of learning?
Why do we think that those who think like us are smarter?
It is easier to answer the second question, but a challenge would be the efford to understand other people’s way of thinking. Accept another viewpoint! Many communication problems can be solved when accepting another viewpoint.
My initial question was which representation could be better to simulate the brain. I think that neuro fuzzy networks are perhaps a better approach to simulating a brain.
A neuro-fuzzy system is a fuzzy system that uses a learning algorithm derived from or inspired by neural network theory to determine its parameters (fuzzy sets and fuzzy rules) by processing data samples. (Nauck, 1997)
The brain strives to understand itself and explain its function. From my small research so far I have found amazing things. A software implementation of the brain can help us understand better its function.
