Brain Activity to Overcome of Fear

This research want to know about the relationship of “courage” to brain imaging in order to uncover of neutral mechanisms associated with. This research was published by Cell Press in June 24 of the journal Neutron, about new insight into what happens in the brain when an individual voluntarily performs an action opposite to what promoted by ongoing fear and may even lead to new treatment strategies for those who exhibit a failure to overcome their fear felling. On this experiment basically want to know how brain nerve will react to the emergency conditions.
To apply this study the volunteer is completed with scanned functional magnetic resonance imaging (FMRI). The object used in this experiment are either a toy bear or a live corn snake, participant categorized as “fearless” or “fearful” depending on how they responded to a validated snake fear questionnaire.

On this experiment the researcher observed that both high subjective fear and high somatic arousal were associated with succumbing to fear and moving the snake farther away. Somewhat surprisingly sometime bringing the snake closer was associated with either high somatic arousal (assessed by skin conductance response) accompanied by low subjective fear (assessed by fear self ratings) or high subjective fear accompanied by low somatic arousal.

When people to do the task revealed that activity in a brain region called as subgenual anterior cingulated cortex (sgACC) that correlated positively with the level of subjective fear when choosing to act courageously but not when choose to succumb to fear. When the level of fear is increase, other activity is decrease the temporal lobe structures and an individual chose to overcome their fear.
