Researchers
from Harvard University Social Cognitive and Affective Neuroscience
Lab wanted to find out why people like the sound of their own voice
so much and if it was linked to the parts of their brain associated
with pleasure and reward.
After
conducting tests using brain scanning technology they found that when
people talk about themselves it triggers the same chemical reaction
they experience during sex and this motivates them to share personal
information more regularly.
During
the fMRI experiment, researchers asked 195 people to talk about
themselves, including their own opinions and personality traits.
They
were then asked to discuss opinions and traits of other people they
knew.
Basically,
talking about yourself with your friends causes a change in the
activity in the nucleus accumbens (NAcc) and the ventral tegmental
area (VTA). Both parts of these brain are linked with releasing
dopamine and dopamine Dopamine is a neurotransmitter that helps
control the brain's reward and pleasure sections.
It
is released when the brain is subjected by certain stimuli, such as
during sex, when taking drugs, eating chocolate and more.
Dopamine
also helps control emotional responses to situations.
It
helps us to see the rewards of certain behaviours but also motivates
us to seek out these rewards.
Dopamine
deficiency results in Parkinson's Disease, and people with low
dopamine activity may be more prone to addiction.
The
presence of a certain kind of dopamine is also associated with
sensation seeking.
Sensation
seeking is a personality trait in people who seek out risky
activities.
Basically, you brain feels like you are having sex without intercourse. I now see why ladies enjoy this a lot. Having pleasure without the stress of a man. Wow. This information is heavy.
