Memory is not a passive record of events but an emotionally driven process shaped by the interplay of brain structures and neurochemicals. This article explores how emotions such as joy, fear, and sadness influence memory formation, consolidation, and retrieval. The amygdala and hippocampus, along with neurotransmitters like dopamine, serotonin, and cortisol, act as key mediators in strengthening or distorting memories. Positive emotions enhance learning and cognitive flexibility, while negative emotions can create vivid flashbulb memories or fragmented recollections in cases of trauma. The paper also highlights the broader role of emotional memory in identity, therapy, mental health, and social connection. Ultimately, emotions serve as both the glue and the filter of memory, shaping not only what we remember but also how those memories guide our behaviour and resilience.
