New Perspectives on Mood
For years, serotonin has been seen as the key to mood regulation, often associated with feelings of happiness. However, new research suggests mood regulation is more complex. While antidepressants like SSRIs adjust serotonin activity, their primary mood benefits may come from promoting neuroplasticity—helping the brain form new neural connections. This means serotonin might play a bigger role in helping us form new behavioral patterns, rather than in directly creating happiness.
