Associative olfactory memory in Drosophila has two components called labile anesthesia-sensitive memory and consolidated anesthesia-resistant memory ( ARM ) . Mushroom body ( MB ) is a brain region critical for the olfactory memory and comprised of 2000 neurons that can be classified into αβ , α′β′ , and γ neurons . Pr... | One of tantalizing questions in neuroscience is how the brain processes memory . Studies in animal models such as fruit fly have brought innovations addressing the general principles underlying memory processing such as acquisition , consolidation , and retrieval .
