The temporal lobe is located beneath the Sylvian fissure on both sides of the brain. It is involved in auditory perception, processing semantics, and forming long-term memory. Disturbances can be caused by ischemia, hemorrhage, lesions, trauma, or epilepsy. Left side lesions affect verbal and visual recall while right side lesions impact tonal recognition and face recognition. Temporal lobe epilepsy is common in Ecuadorian children and adolescents and is often complex partial type linked to behavioral and affective issues. Epilepsy surgery in Ecuador focuses on the temporal lobe.

- 2. The temporal lobe is a region of the cerebral cortex that is located beneath the Sylvian fissure on both cerebral hemispheres of the mammalianbrain Directionally, the temporal lobes are anterior to the occipital lobes, inferior to the frontal lobes and parietal lobes, and lateral to the Fissure of Sylvius, also known the lateral sulcus.
- 3. The temporal lobes are involved in the primary organization of sensory input The temporal lobe is involved in auditory perception and is home to the primary auditory cortex . It is also important for the processing of semantics in both speech and vision The temporal lobe contains the hippocampus and plays a key role in the formation of long-term memory .
- 4. Disturbance in function of the temporal lobe may be caused by ischaemic or haemorrhagic damage, as with a cerebrovascular event (CVE). Disturbance of temporal lobe function may also occur with space-occupying lesions, trauma and may be associated with epilepsy.
- 5. The most common cause of temporal lobe lesions is a cerebrovascular event: Space-occupying lesions may be primary tumours, benign or malignant. trauma from head injury may be involved or surgical damage when removing a tumour from that region. Frontotemporal lobe dementia. Other pathologies such as multiple sclerosis can affect the temporal lobes
- 6. Disaventage have identified eight principle symptoms of temporal lobe damage: 1) disturbance of auditory sensation and perception 2) disturbance of selective attention of auditory and visual input 3) disorders of visual perception 4) impaired organization and categorization of verbal material 5) disturbance of language comprehension 6) impaired long-term memory 7) altered personality and affective behavior 8) altered sexual behavior.
- 7. Left side lesions result in decreased recall of verbal and visual content, including speech perception. Right side lesions result in decreased recognition of tonal sequences and many musical abilities. Right side lesions can also affect recognition of visual content (eg. recall of faces).
- 8. Issue in Ecuador Temporal lobe epilepsy is one of the most common disorders in children and adolescents in Ecuador being most common complex partial type. These epilepsies were found related to psychiatric morbidity of behavioral and affective and were more common in males. Epilepsy surgery in Ecuador is safe and provides results comparable to other international centers. By far there have been only temporal lobe surgery based on the application of protocols in Phase I.
