example: i was at home and i was washing my hands with antibacterial soap and my friend comes in with a cigarrette. and the smell of smoke and cigarrette makes me automaticaly think of my piercer. (doesnt smoke in the shop but smokes after he does his job).
Answer:
The hippocampus is the part of your brain that is related to memory, particularly, associative memory. So, this is the structure that triggers a memory when you experience something familiar (like a smell).
Or as the first article puts it: "Not only is the hippocampus filing away memories, it is connecting them with other related memories and giving the memories meaning."
If you want to get really technical about it: "The primary olfactory cortex, in which higher-level processing of olfactory information takes place, forms a direct link with the amygdala and the hippocampus. Only two synapses separate the olfactory nerve from the amygdala, which is involved in experiencing emotion and also in emotional memory. In addition, only three synapses separate the olfactory nerve from the hippocampus, which is implicated in memory, especially working memory and short-term memory. Olfaction is the sensory modality that is physically closest to the limbic system, of which the hippocampus and amygdala are a part, and which is responsible for emotions and memory. Indeed this may be why odor-evoked memories are unusually emotionally potent." (second article)
your olfactory is what its called. it is the place in the brain that recieves smells from your nose. since your brain is all linked together by firing neurons, it triggers a neuron and makes you remember a situation that the smell was present for. some people with mental disorders have complications with their sense of smell and will constantly smell burning rubber or other smells.
The sense of smell is the most primal, and so it seems to be the strongest link to memory impression.
The detection of individual molecules transmitted by dispersion predates any other sensory input, and so our brains retain associated sensory input that accompanies specific odors more significantly than with any other sense.
The sense of smell is very important to survival, even though we are much safer now than humans were in the past, we still physically prioritize memory associated with specific scents.
Aromatherapy can even be used to help you study and retain information!
What in the brain makes you remember people or places just by the smell of something? Its the primitive brain structure that survived so long by being arranged to recognize "IT IS IMPORTANT TO REMEMBER ANYTHING WITH A DISTINCTIVE ODOR," because its usually represents food, safety, or danger...The olfactory cortex and the hippo campus are just where the brain "lights-up" when the smell and memory are activated...Medical science still doesn't even know HOW memory works, in spite of popular belief...
Wow, Psychgrad... She could have Googled a textbook herself...
Most of our memories are connected to our sense of smell. which part of the brain does that I'm not sure, But I do know that smell is what first attaches a baby to it's mother and father. Smell is what you remember the most. Close you eyes and think about the smell of your house as apposed to any other house that you know. Even the most clean houses have their own unique smell. Each person has their own unique smell. Smell is what attracts people to each other especially sexual partners. Our bodies release chemicals called pheromones which is a unique smell that we all have and it's what on a non concies level attracts people to us sexually. So yes memories and other things are brought to us by smell.
