Understanding the brain's resilience: Unravelling the mysteries of neuronal degeneration

Each brain is unique, not only in its connections but also in the molecular composition of its neurons, particularly ion channels. Despite their variability, the brain functions reliably -- a paradox known as 'neuronal degeneration' (distinct from pathological degeneration). Researchers used mathematical tools to uncover two distinct mechanisms enabling this robustness. These mechanisms ensure reliable neuromodulation, even with variations in ion channels, offering insights into how the brain adapts its activity to internal and external signals.
