Damage to the left hemisphere of the cerebral cortex can result in various emotional and psychological consequences, but one significant outcome often associated with such damage is heightened aggression and anxiety. This is rooted in the left hemisphere's role in language and communication, as well as its involvement in the processing of positive emotions.

When the left hemisphere is compromised, there can be an imbalance in emotional processing, leading to difficulties in managing negative feelings such as fear or anxiety. Additionally, the left hemisphere's damage can disrupt normal behavioral regulation, potentially triggering increased aggression. This reflects the broader understanding in neuroscience that emotional regulation and behaviors can be significantly influenced by the integrity of brain regions, with the left hemisphere often linked to more positive affective responses, while the right hemisphere is often associated with negative affect.

Intense emotional expression, uncontrollable laughter, and indifference to emotional stimuli typically point to different types of brain damage or emotional dysregulation patterns, often more aligned with right hemisphere damage or specific conditions that affect emotional processing in distinct ways, rather than specifically with left hemisphere damage.
