How the thalamus shapes newborn brain waves
Thalamic contributions to the developing EEG
This project looks at how a deep brain region called the thalamus helps form the brain wave patterns seen in newborns to better recognize and understand brain injury in at-risk infants.

What this research studies
Researchers are using un-anesthetized neonatal rodent models that show brain activity patterns similar to human fetuses and newborns to study how brain rhythms develop. They record electrical activity through the depth of the cortex and matching thalamic networks and will change the activity of specific thalamic neurons to see how EEG features are altered. The goal is to build a map linking abnormal EEG patterns to disruptions in particular brain areas and cell types. That map could guide future work to improve bedside EEG interpretation for fragile newborns.
Who could benefit from this research
Good fit: Newborn infants who are at risk of brain injury or who are already having EEG monitoring are the group most likely to benefit from the findings of this research.
Not a fit: Because the project uses animal models to study basic mechanisms, it does not provide direct treatment or immediate benefit to individual patients, and people without newborn brain concerns are unlikely to gain direct benefit.
Why it matters
Potential benefit: If successful, this work could help clinicians read newborn EEGs more accurately so they can detect thalamic-related brain injury earlier.
How similar studies have performed: Previous clinical and animal studies have connected thalamocortical circuits to neonatal EEG patterns, but directly manipulating thalamic neuron types to map specific EEG features is relatively novel and experimental.
