Neuroscience has shown that emotions are generated by multiple structures in the brain. The rapid, minimal, and evaluative processing of the emotional significance of the sensory data is done when the data passes through the amygdala in its travel from the sensory organs along certain neural pathways towards the limbic forebrain. Emotion caused by discrimination of stimulus features, thoughts, or memories however occurs when its information is relayed from the thalamus to the neocortex. Based on some statistical analysis, some scholars have suggested that the tendency for anger may be genetic. Distinguishing between genetic and environmental factors however requires further research and actual measurement of specific genes and environments.
