Brain

The brain fascinates me – different facets of it - which hardly get noticed because we are so used to it. Different inputs get treated differently, and it constantly works involuntarily on those. And, sometimes it generates its own inputs (dreams) which do not get stored in the memory, but sure have some importance which we do not understand. How is so much information packed in our genome? Or should I ask, how does the brain know what to do? I think it is the wrong question to ask. We never ask how a polymer molecule knows how to behave in a given environment. We simply say that if we know the density of states of the polymer, then we will know how it will behave based on the set of rules we have already figured out. The density of states does not need a large memory to be saved, but it defines the polymer completely. I am sure someday we will find the density of states of the brain. Ghosh! What will be the possibilities then!
