What Triggers Our Memories?

smellingflowerOur ability to smell transports us back to emotional memories. Not only can smell help us reminisce, but it also influences people’s moods and affect their work performances. Above our nasal cavities, we have something called the olfactory bulb that receives neural input about detected odors. The olfactory bulb is part of our brain’s limbic system, an area that is operates relatively close with memory and feelings. Not only is the olfactory bulb close to our limbic system, but it also has profound access to the amygdala. The amygdala is where emotions are processed. Although scent trigger memories, the brain has to be conditioned for the responses, relating it to visual information or remembering when/where the scent has been smelled before. Perhaps this could also be probable reasoning for why different people prefer different scents.
