Affective neuroscience is a branch of neuroscience that studies the neural mechanisms underlying emotions. It explores how the brain processes feelings such as happiness, sadness, fear, and anger. Researchers in this field use various techniques, including brain imaging, to identify which areas of the brain are activated during emotional experiences. This discipline combines insights from psychology, biology, and cognitive science to understand how emotions influence behavior and decision-making. Key areas of interest include the role of the amygdala in fear responses and the impact of neurotransmitters like serotonin and dopamine on mood regulation.
