What is cathodal transcranial direct-current stimulation?
It is a non-invasive brain stimulation technique that uses direct current to modulate neuronal activity.
How does the multi-electrode array work?
It records electrical activity from multiple sites in the brain slice, allowing for detailed analysis of neuronal behavior.
What are seizure-like activities?
These are abnormal electrical discharges in the brain that resemble those seen in epilepsy.
Why use an in vitro model?
In vitro models provide controlled environments to study specific neuronal pathways and responses to stimulation.
What are the implications of this study?
The results may inform future therapeutic strategies for managing drug-resistant epilepsy.
