Amygdala In The Limbic System

Decent Essays
In the limbic system, there are two almond shaped groups of amygdalae. The two amygdalae (left and right) together make up what we call the Amygdala. Amygdala in Greek means almond, hence corresponding the name with the shape. The amygdala’s right and left portions differ in specific processing. The left and right amygdalae also have different roles when it comes to the encoding of emotional memory for events. In humans the right amygdala is larger than the left (Murphy et al., 2009) this could contribute to the right hemisphere being more dominant for emotion. The amygdala can also differ according to sex. For example in both humans and rats, a male’s amygdala tends to be larger than a female. Nevertheless the two amygdalae work together in…show more content…
The amygdala receives projections from the hippocampus, the thalamus, and the prefrontal cortex. Basically projections come from a variety of several structures. Research shows that the amygdala is shown to perform a primary role in the processing of memory, decision-making and emotional reactions. The amygdala is also exceedingly responsive to social and emotional stimuli as conveyed vocally, through touch, and via the face (Gloor, 1992; Halgren, 1992; Kling & Brothers 1992; Morris et al., 2013; Rolls, 2007, 1992). The amygdala is responsible for a lot of our survival-related needs. For example being able to identify threats. It also helps connect memories with emotion. Some people after trauma suffer from Post Traumatic Stress Disorder. Traumatic events can actually alter the structure and function of people’s brains (H. (2016) How To Heal The Brain After Trauma). Which results in the amygdala being in a highly alert loop. Their brains tend to stay on alert, seeking out threats. It is hard for them not to feel anxious, scared or however undergoing the event that caused their PTSD, made them feel. They are easily triggered and can act as if they are reliving the trauma. They can’t push their emotion to the back of their
