Brain's Balance of Excitation and Inhibition
The brain maintains a delicate balance between excitatory and inhibitory neurons, which is crucial for healthy functioning. Recent research reveals that inhibitory neurons are more active and specific than previously thought, playing key roles in learning and memory. Additionally, a third category of neuromodulatory neurons influences brain activity on slower timescales, adding complexity to neural regulation. Understanding these interactions could lead to better treatments for neurological disorders caused by imbalances.
