San Francisco, we often hear the phrase, 'Basic shameless', or 'It's broken veins shame' directed at people who are assessed have no shame. Be careful if you have started to lose a sense of 'cock' because it means that there are parts of the brain that have been damaged.Scientists from the University of California, San Francisco and the University of California, Berkeley managed to reveal what part of the brain that is responsible for the show at least a sense of shame.
According to researcher Virginia Sturm, his team has identified a part of the brain on the right front of the so-called 'anterior cingulate cortex pregenual' as a key cause of human shame.
"This is the area of the brain that can predict a person's behavior. The smaller part of the brain is the less people have a sense of shame," Virginia said as quoted by ScienceDaily, Sunday (17/04/2011).
Central shame in the 'anterior cingulate cortex pregenual' This position is deep in the brain that is the right front. Another function of the brain, among others, regulate heartbeat and breathing, emotional, addictive behavior and decision making.
So it is in people whose brains healthy, when to feel ashamed of the brain will be functioning optimally. Shame will make the blood pressure rises, heart rate increases or changes in breathing.
But in people who have a low sense of shame as in patients with Alzheimer's or dementia (senile), brains in this section were smaller than usual. They generally become more indifferent to the things people say embarrassing because the brain 'pregenual anterior cingulate cortex' such as 'blinded' to shame.
"When you lose the ability of the brain in this area, you will lose the shame response," Virginia said as quoted by LiveScience.
The scientists believe that the bigger the specific brain region, the stronger the workings of the brain associated with that function. For example, people with an open personality (extrovert) has a central processing larger brains, while those who had central nervous easy detection of errors is greater.
In conducting the study, researchers asked 79 participants to sing karaoke song 'My Girl', the 1964 hit song that dinyayikan Temptations. Participants were healthy and there are some who suffer from degenerative nerve diseases.
Participants voice recorded and played back without any accompanying music. Participants are embarrassed by his voice directly visible from the expression on his face, then sweating and heart rate increases. Conversely patients who suffered a nervous breakdown looks indifferent and lacking a sense of shame even when their voices heard very embarrassing.
