Prediction of Anxiety and Memory State

This study is looking at how anxiety and memory states affect brain activity in people with temporal lobe epilepsy — a form of epilepsy that originates in the memory and emotion centers of the brain. Researchers will use electrodes temporarily placed in the brain (during a procedure already planned for epilepsy care) to measure brain signals while participants complete simple tasks. **You may be eligible if...** - You have known or suspected temporal lobe epilepsy - You speak English or Spanish fluently - You can read at approximately a 7th grade level - Your planned brain monitoring will include electrodes in the hippocampus (memory area) **You may NOT be eligible if...** - You have uncorrected hearing or vision problems - You have an IQ below 70 - You have a history of psychosis, electroconvulsive therapy, or active anxiety, depression, or bipolar disorder - You have a neurodegenerative disease, HIV, cancer with spread potential, or kidney failure Talk to your doctor to see if this trial is right for you.
