Misplaced Neurons Disrupt Brain Wiring—Here’s Why

What Happens When Neurons Are in the Wrong Place?

Your brain’s development is like constructing a complex electrical grid, where every neuron must be in its exact place for the system to function smoothly. But what happens when neurons don’t settle where they should?

A groundbreaking study led by Professor Silvia Cappello at LMU’s Biomedical Center reveals that misplaced neurons are hyperactive, which may contribute to developmental disorders like periventricular heterotopia (PH), a condition linked to

Seizures
Learning difficulties

The Science Behind Overactive Neurons

Using stem cells from patients with PH, researchers created 3D brain models (cerebral organoids) to study how these neurons behave. The findings were striking:

Hyperactive Neurons: Misplaced neurons had a lower stimulus threshold, making them more excitable.
Genetic Link: Mutations in the DCHS1 gene played a key role in this hyperactivity.
Altered Connections: These neurons had more complex structures and unusual synaptic connections, which might explain their excessive electrical activity

A Potential Breakthrough: Lamotrigine Shows Promise

Excitingly, researchers reversed this abnormal hyperactivity using Lamotrigine, a common antiepileptic drug. This suggests potential new treatments for neurological disorders caused by neuron misplacement.

“Our findings offer new insights into how the brain’s wiring becomes disrupted,” says Prof. Cappello. “They could help explain neurological problems associated with PH and open doors for new therapeutic approaches.”

What This Means for Future Treatments

Understanding how misplaced neurons affect brain function could lead to targeted therapies for conditions like

Epilepsy
Learning disorders

This research paves the way for more effective interventions, offering hope to those affected by neurological conditions.
