Have you ever noticed how certain scents can transport you back to childhood memories, moments with loved ones or just those very special days we don't want to forget? Our sense of smell has a bigger connection to memory and emotion than any of our other senses and there's actually a fancy scientific reason for it!
When we taste, see, touch or hear these senses automatically relay to our brains, heading straight for the 'thalamus', a part of our brains just above the brain stem which relays information to other parts of the brain like the hippocampus (responsible for memory) or the amygdala (responsible for emotional processing).
The way our brains processes smell is completely different then other senses, potentially hinting at why smell can be so emotionally charged. When we smell something this information automatically bypasses our thalamus and instead is relayed directly to the olfactory bulb which is directly connected to our amygdala and hippocampus in the brain. Scientists now believe that memories around smell are actually saved directly in the olfactory bulb itself meaning that our brain's smell center stores it's own long-term 'scent memories' AND has a direct connection into our brain's memory center!
