THE MAGAZINE ON HEALTH: WHAT ABOUT MEMORY? This is a series of 9 articles on memory. How does it work (function), and how can we explain memory loss and memory gain? 1) How has the ‘sea slug’ helped us understand memory? Eric Richard Kandel a psychiatrist and neuroscientist conducted a study on how brain neurons change when new memory paths are formed. Kandel studied Aplysia Californica, which in simple terms is the Sea Slug. This creature has a simple nervous system when compared to humans, but the slug has some of the largest neurons in the animal kingdom, which made it easy to observe. The Aplysia was tested each day over a period of weeks; each day it made adjustments faster then it did the day before, which showed a lasting memory. Most importantly, Kandel studied the neuron and identified the changes in the structure and functioning of the neurons involved with learning and memory. When the slug added functions to memory through repeated stimulation, considerable changes occur in neurons involved in the process – showing the role of neuron change in memory through repetition. This helps us understand how repetition of new behaviours over time can form changes to neurons in the brain for lasting effects. 2) The gateway for memory: How does memory and the brain’s hippocampus and temporal lobes relate? Sitting in the temporal lobe region of the brain is the hippocampus, which is known as the ‘gateway’ for our biographical memory, including the places we’ve lived in our lives. This is the part of the brain where our lived-experiences get stored. (Physically, the hippocampus is tubular and curved located above each ear and around 4 cm into the brain). This is in the lower region of the temporal lobe of each hemisphere. The reason this is called ‘The Gateway’ is because gateway, new experiences pass thru the hippocampus before it goes into the closet of
