Furthermore‚ Goleman described that the inner brain or amygdala‚ which is responsible for triggering the emotional feelings. Sometimes it is responsible for preprogrammed “primitive” impulsive actions. The region of the inner brain is located just above the end of the spinal cord‚ constantly informs us about what we feel about anything and everything in our daily lives. It gives us the “gut feeling” about everything‚ although we cannot rationally explain why. There is a storage place for the accumulated

If the amygdala deems a situation threatening‚ it emits stress signals which move throughout the body triggering reflex responses such as dilating pupils and increasing blood flow to alert and prepare the body for danger. The amygdala also highlights important events in a memory‚ passing this information on to the hippocampus‚ telling it to store this memory. PTSD sufferers have a hyperactive amygdala that remains active for long periods‚ increasing stress and anxiety. The affected amygdala focuses

Differential Amygdala Activity: Affective Processing Based on the theory that psychopathy would go along with abnormalities in affective‚ or emotional‚ processing due to the fact psychopaths display emotional abnormalities such as lack of empathy‚ research was conducted in 2001 to find out more about the neural underpinnings of this (Kiehl et al.‚ 2001). To study this‚ participants underwent fMRI while performing an affective memory task. Eight repetitions of twelve words were carried out‚ four containing

Abstract Discussed is some of the research that has been conducted on the role of the amygdala in anxiety‚ as well as the role of GABA and benzodiazepines in anxiety. Research has indicated through amygdala lesions and stimulation that the amygdala does indeed play a major role in the expression of anxiety. Research has also indicated‚ through drug infusions to the amygdala‚ that benzodiazepines cause anxiolysis (by increasing GABA transmission)‚ and that benzodiazepine antagonists increase anxiety

Frontal Lobe/Amygdala Activity Quiz Experience 1. Purpose -The purpose of the experiment was to determine which part of the brain different people use when accidentally bumped into. The experiment was done in various places to people of different genders so the experiment was more random. The prefrontal cortex was the part of the brain that reasoned with what was happening; when people use this part of their brains their reactions are milder. The amygdala (part of the limbic system)
