It has been said that human brain is a condensed version of the Universe. But little is known that human brain follows a very well defined structure of the Universe. This structure is 22/6/4. This is the same structure for all creation from particles, to atoms, planets, stars, and galaxies.
Advancement in Cognitive Neuroscience enables us to understand our brain in detail. Our brain can be mapped into the 22/6/4 structure.
The Six Sense-Organs
The six sense-organs are clearly the receptors in the human body. The receptors can be found in the eyes, the ears, the nose, the tongue, and all over the body. They correspond to the first five sense-organs.
The location of the Mind Indriya sense-organ is within the function of the cerebellum. An article from National Institutes of Health of US National Library of Medicine, The Cerebellum and Emotional Experience, shows that the cerebellum, the oldest part of the human brain contains in it the intention sense-organ functions.
The cerebellum is typically recognized for its role in the coordination of motor behavior, but an increasing number of empirical studies have recognized its involvement in cognitive and emotional functions as well. For instance, recent studies report that patients with cerebellar damage show impairments in executive function, language, sensory processing and emotion regulation. In schizophrenia, a psychiatric illness where cerebellar pathology has been considered relevant, our group has observed that the cerebellum shows reduced activity during appreciation of hedonic features. Little is known, however, regarding the mechanisms by which cerebellar damage leads to impaired emotion regulation.
The Six Internals
The sense-organs work like input / output devices in the computer relaying signals to the device adapters. These device adapters simply perform “picture taking” or “sound recording” transferring the externals to the internals. Human brain has these internals, which is part of the 22/6/4 structure, as well.
The thalamus contains many functions other than being the internals for image, sound, taste, and touch. Olfactory bulb is where the smell internal is located. These five internals by themselves have little meaning until the information they contain are being interpreted. They relay the information to their corresponding consciousness and also to the amygdala which begin to provide some meaning. An example below, Fear Response, provides a better understanding how they work together. The above form the Twelve Spaces.
The Six Consciousness
The consciousness of eye, ear, nose, tongue are located in the various sensory cortex areas.
The Mind Consciousness is a little difficult to locate. Fortunately, an article in the New York Times on February 6, 2007, A Small Part of the Brain, and Its Profound Effects, helps in locating it at the insula.
According to neuroscientists who study it, the insula is a long-neglected brain region that has emerged as crucial to understanding what it feels like to be human.
They say it is the wellspring of social emotions, things like lust and disgust, pride and humiliation, guilt and atonement. It helps give rise to moral intuition, empathy and the capacity to respond emotionally to music.
Its anatomy and evolution shed light on the profound differences between humans and other animals.
The insula also reads body states like hunger and craving and helps push people into reaching for the next sandwich, cigarette or line of cocaine. So insula research offers new ways to think about treating drug addiction, alcoholism, anxiety and eating disorders.
Of course, so much about the brain remains to be discovered that the insula’s role may be a minor character in the play of the human mind. It is just now coming on stage.
The activity of the insula in so many areas is something of a puzzle. “People have had a hard time conceptualizing what the insula does,” said Dr. Martin Paulus, a psychiatrist at the University of California, San Diego.
If it does everything, what exactly is it that it does?
For example, the insula “lights up” in brain scans when people crave drugs, feel pain, anticipate pain, empathize with others, listen to jokes, see disgust on someone’s face, are shunned in a social settings, listen to music, decide not to buy an item, see someone cheat and decide to punish them, and determine degrees of preference while eating chocolate.
It is important to note that the Six Consciousness is like the operating systems device drivers and for human beings they contain our conditioned preferences. The above form the Eighteen Spheres.
The Aggregates of Mental (Formations), Sensations, and Perceptions
These three aggregates wrap around the 6 Consciousness. The Aggregates of Mental (Simple) is located at the frontal lobe. The Aggregates of Mental (Abstract) is located at the Prefrontal lobe. The Aggregates of Sensations are located in both the Pariental lobe and the Occipital lobe. The Aggregates of Perceptions is located at the temporal lobe.
The following example shows how sense-organ, internal, and consciousness work together in a fear response scenario.
Example 1. A person sees a snake, the eye sense-organ sends the signal to the thalamus where the image internal is located (A). The image internal in thalamus relays the signal to the amygdala (B) and the amygdala makes the person run. The image internal in thalamus also sends the information to the primary visual cortex (C) and it confirms it is a snake (D). The person continues to run until it is safe.
Example 2. A person sees a hose, the eye sense-organ sends the signal to the thalamus where the image internal is located (A). The image internal in thalamus relays the signal to the amygdala (B) and the amygdala makes the person run. The image internal in thalamus also sends the information to the primary visual cortex (C) and it confirms it is a only a hose (B). The person stops running.
A brain is a union of cells. In the 5 billion years of the Earth history, the evolution has take the brain structure around through various paths. What we have in our human brain is an implementation of the 22/6/4 structure.
