– The Temporal Lobe

The temporal lobe lies just behind our ears and contains the auditory cortex. This allows us to interpret sound. The temporal lobe stores most of our memories and is involved in aspects of language, including our ability to use language and understand what we hear.

Like the frontal lobes, the temporal lobe is involved in regulating certain aspects of personality. Deep inside the temporal lobe are the structures of the hypothalamus and limbic system. The hypothalamus is involved in instinctual behaviours such as aggression, sexual arousal, appetite, thirst and temperature control. The limbic system is in control of emotional reactions.

Damage to these areas can severely disrupt our emotions resulting in sudden and dramatic mood swings; and can also lead to inappropriate social behaviour such as hyper-sexuality and impulsiveness.
