Brain carries on cell to cell communication and for which they depend on specialized neuron nerve cells. These are responsible for communicating information in both chemical and electrical forms. There are also several different types of neurons responsible for different tasks in the human body.
The property that makes neurons unique is their ability to send signals to specific target cells over long distances. They send these signals by means of an axon, which is a thin protoplasmic fiber that extends from the cell body and projects, usually with numerous branches, to other areas, sometimes nearby, sometimes in distant parts of the brain or body.
Axons transmit signals to other neurons by means of specialized junctions called synapses. The essential function of the brain as mentioned before is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses. (Even the brain of a fruit fly contains several million.) The functions of these synapses are very diverse: some excite the cells that are to carry messages forward or inhibit them. Like forbidden desires that make themselves felt are checked by the conscious mind, these cells as a matter of course are screened at synapses.
An important point to remember is that synapses can get from the bulk of messages the trend of thinking that goes on. Thus one makes a habit of creative activities will find synapses an ally. In short those who want to achieve naturalness in their responses to the world need to make them accustomed to their natural inclinations. A pianist who trains often naturally tends to play naturally and better.
It is widely believed that activity-dependent modification of synapses is the brain’s primary mechanism for learning and memory.
A single axon may make as many as several thousand synaptic connections with other cells.When an action potential, traveling along an axon, arrives at a synapse, it causes a chemical called a neurotransmitter to be released. The neurotransmitter binds to receptor molecules in the membrane of the target cell. Schizophrenia patients suffer from disjointed thoughts and actions on account of inability in neurotransmitter.
In short much of our vaunted progress or the perverseness to let injustice and inequality rampant owe to electrical and chemical impulses that permeate the universe. If you probe deep down what are we but flashes and molecules reality of which lay in another dimension altogether.
Since I shall come to that in subsequent posts let me say that at quantum level we are timeless. The world that we made are from rational thoughts and if looks so strange and irrational we only need to conclude we relied on the medium of brain, disproportionate to its true nature. Brain can only do so much and no more. We have been deceived by our own cleverness.
