How Smells Trigger Memories

The video explores odor-evoked autobiographical memory, where smells trigger vivid memories, often from early childhood. Unlike other senses, smells bypass the thalamus and directly connect to the brain's memory and emotion centers, making them powerful memory triggers. A study using fMRI showed that smells activate emotional processing centers more than verbal cues. However, smell memories are perceptual and not useful for learning concepts, like for exams.
