The awaking time

 One of his students asked Buddha:

Are you the messiah?

No,

 ...answered Buddha.

Then are you a healer?

No,

 ...Buddha replied.

Then are you a teacher?

 ...the student persisted.

No, I am not a teacher.

Then what are you?

 ...asked the student, little bit  exasperated.

I am awake,

 ...Buddha replied.
This is a state of brain.
Therefore, noticed we, the brain is useful to examine.

Hi, now I understand better even my ex-neighbor:
The participants in the high psychopathy group exhibited significantly less activation in the ventromedial prefrontal cortex, lateral orbitofrontal cortex, amygdala and periaqueductal gray parts of the brain, but more activity in the striatum and the insula when compared to control participants, the study found.

The high response in the insula in psychopaths was an unexpected finding, as this region is critically involved in emotion and somatic resonance.

Hence, examining the neural response of individuals with psychopathy as they view others being harmed or expressing pain is an effective probe into the neural processes underlying affective and empathy deficits in psychopathy,”

A marked lack of empathy is a hallmark characteristic of individuals with psychopathy,

said the lead author of the study, Jean Decety.

This is the first time that neural processes associated with empathic processing have been directly examined in individuals with psychopathy, especially in response to the perception of other people in pain or distress, 

he added.

Decety is one of the world’s leading experts on the biological underpinnings of empathy. His work also focuses on the development of empathy and morality in children.

There prisoners, who are psychopaths lack the basic neurophysiological `hardwiring´ that enables them to care for others, according to a new study by neuroscientists at the University of Chicago and the University of New Mexico.
Relative to non-psychopathic criminals, psychopaths are responsible for a disproportionate amount of repetitive crime and violence in society.
The results of the study, which could help clinical psychologists design better treatment programs for psychopaths, are published in the article, Brain Responses to Empathy-Eliciting Scenarios Involving Pain in Incarcerated Individuals with Psychopathy, which appears online April 24 in the journal JAMA Psychiatry..
