This research investigates using light-sensitive proteins to control cardiac electrical activity and treat arrhythmias. By precisely guiding heart rhythms with light rather than drugs or shocks, the study identifies proteins capable of suppressing dangerous premature signals, offering a reversible, non-invasive alternative to current heart disease treatments.

Electrical signals in the body depend on ion channels that regulate salt movement across cell membranes. When these channels malfunction, diseases like epilepsy and heart arrhythmias can occur. This research decodes how faulty ion channels work, revealing potassium-based mechanisms that could restore electrical signaling and guide new therapies.

This research investigates transcranial electrical stimulation (tACS) as a non-invasive way to modulate prefrontal cortex activity in people with severe mental disorders such as schizophrenia. By measuring brain activity, cognition, and behavior, the study aims to identify conditions where tACS is effective and offer a safe, accessible therapeutic alternative.
