The Amygdala Response to Fear

Journal of Cognitive Neuroscience is investigating articles about the reactions of amygdala to terrible faces and how it differs between their own culture and other cultures. The amygdala is specially designed to detect threats including terrible facial expressions. Researchers in this study assumed that the amygdala would respond better to the culture of the individual. This survey was conducted for local Japanese participants and American white people. Functional brain images were obtained at two neuroimaging facilities.

In response to fear of subconscious, it shows correct amygdala activity, superfear shows a greater left amygdala response. People exposed to subconscious images flash for 16.7 milliseconds. This informs potential threats and reproduces ultrasound images for over 0.5 seconds. In addition, extreme fear shows more sustained cortical activity, subconscious fear may not require conscious supervision but suggests that extreme fear requires higher order treatment

Perhaps you have heard about the amygdala. It is a super fast part of the brain that detects potential threats and triggers fear reactions such as fighting and escape. The amygdala body signals the hypothalamus, releases stress hormones (such as cortisol and adrenaline), encourages awakening and urges them to establish a safety strategy. Fear reactions are very effective in securing our safety, but there are drawbacks. When the amygdala body is in danger, it actually blocks our prefrontal cortex (responsible for critical thinking) to react quickly. This can save our lives, or it can lead us to stop us in a normal way, think and act, and avoid future dangers. Emotional intelligence writer Daniel Goleman called this Amygdala hijacking

Many people think the amygdala is a small almond-shaped area deep within each hemisphere of the brain. Author Daniel Goleman has created the term "almond hijack" to represent inflammatory rhetoric and image design. This is truly the left to believe what people will do with their opponent's media. Therefore, it is necessary to understand it in order to resist the operation of people who are distressed by personal, political and corporate interests. The first thing to understand is that emotions look like fear and may sound like fear and smell, but neuroscientists believe that it is actually quite different.
