How the brain processes what we see, hear, and feel

Researchers want to understand how a specific part of your brain called the thalamus helps you become aware of what you see, hear, and feel. This study uses brain imaging (MRI scans), eye-tracking cameras, and behavioral tasks to map out these brain systems. Some participants with epilepsy who already have electrodes placed in their brain may also participate in a more advanced phase where researchers directly record and stimulate the thalamus.

Most research focuses on how the outer layers of the brain process information, but much less is known about the deeper brain structures that control whether we actually notice things. Understanding this could lead to better treatments for attention problems, awareness disorders, and conditions like epilepsy.
