Here's why smells trigger such vivid memories

Updated:7 years, 3 months ago

New Delhi, Jul 24 (ANI): Smells have a stronger link to memory and emotion than any of the other senses, and neuroscience may know the reason why. A mechanism that allows the brain to recreate vivid sensory experiences from memory has been revealed. Neurobiologists at the University of Toronto have shed light on how sensory-rich memories are created and stored in our brains. Using smell as a model, the findings offered a novel perspective on how the senses are represented in memory. The study also tends to explain the loss of ability to smell can be recognised as an early symptom of Alzheimer's disease. Alzheimer’s most common early symptom is difficulty in remembering recent events and having difficulty in remembering things. There is a strong connection between memory and olfaction which is the process of smelling and recognizing odours. There are at least 1,000 different smell receptor types, which regenerate throughout your lifetime, and change according to what you are used to smelling. Researchers added that with a better understanding of the neural circuits underlying odour memory, tests that directly and effectively examine the proper functioning of these circuits can be developed.
