The smaller temporal lobe
So, what is the evidence showing that the structures of the temporal lobe are smaller? Various studies have shown that the hippocampus and amygdala are smaller in size. There have also been components of the limbic system and regions of the Superior Temporal Gyrus (STG) that show to be smaller than other areas in the brain. This is important because the limbic system is involved in controlling a person's moods and emotions, and the STG is crucial in both language function and processing. When researchers analyze how severe a patient's symptoms are, it is commonly found to be reliant on the varying sizes of these language areas.
