Summary
This trial uses small electrical pulses to stimulate a part of the brain called the amygdala. It targets patients with memory problems, such as those from brain injuries or PTSD. The treatment aims to improve memory by enhancing the brain's natural memory circuits, especially when emotions are involved. This method has been explored for various neurological and psychiatric conditions, including memory improvement and PTSD.
Who is the study for?
This trial is for English-speaking individuals who can consent to participate, have been diagnosed with epilepsy, and are scheduled for long-term video monitoring of seizures. They must be set to receive intracranial depth electrodes in specific brain regions related to memory.
What is being tested?
The study is testing the effects of stimulating the amygdala—a part of the brain—on memory functions. It aims to improve understanding relevant to conditions like traumatic brain injury and post-traumatic stress disorder that affect memory.
What are the potential side effects?
While not explicitly stated, potential side effects may include discomfort at electrode sites, headaches, or changes in mood or cognition due to stimulation.

Experimental Treatment
Group I: Brain StimulationExperimental Treatment1 Intervention
Neurosurgical epilepsy patients that undergo placement of medial temporal electrode for seizure localizations will be recruited. All participants will view a series of images of emotionally-neutral objects on a computer screen. After each item presentation, they will randomly undergo either active-BLAES or sham-stimulation. Over subsequent days, free recall and recognition memory for these items, relative to new distractor items will be tested. Memory for items presented with and without stimulation will be compared. Brain activity recorded in the medial temporal lobe during item presentations will be used to predict subsequent memory. Such good and bad memory states (biomarkers) will be used to perform closed-loop stimulation when bad memory states are detected in order to enhance subsequent memory.

Other Research
The most common treatments for memory loss often involve pharmacological agents and behavioral therapies that target the brain's memory-related structures, such as the amygdala and medial temporal lobe. For instance, memantine, an NMDA receptor antagonist, is used to regulate glutamate activity, which can help in reducing neuronal damage and improving cognitive function.
Behavioral therapies may include techniques to enhance emotional engagement, which can activate the amygdala and improve the consolidation of long-term memories. Understanding these mechanisms is crucial for memory loss patients as they highlight the importance of both chemical and emotional factors in memory retention, offering a more comprehensive approach to treatment.
