The study found that this technique can indeed lead to long-term changes in neuron behavior that don’t require any other interventions. At the moment, researchers plan to use the new technique as a research tool to better understand what’s happening in the brain, but hopefully, in the future, it can be used therapeutically for brain-related conditions like Alzheimer’s or psychiatric diseases. One easy place to start is with supplements called nootropics, which optimize brain health and promote memory, mood balance, and cognitive function. Here are a few highly rated nootropics to look into. Another great practice for promoting brain health is meditation. Meditation has been shown to keep your hippocampus, the part of the brain responsible for learning and emotional regulation, healthier, and some studies have found it can help decrease brain cell volume in the amygdala, which is the part of the brain responsible for fear, anxiety, and stress. It has even been shown to alter the behavior and conductivity of neurons3, like how light therapy did in this new MIT/Harvard study.
