Article on Memory - Forgetting is the New Normal

Memory refers to the process that are used to acquire,store retain, and later retrieve information. Memory loss is normal,some people end up with some form of dementia such as Alzheimer's disease. In the magazine article "Forgetting is the new normal" it said that "Up until a decade ago the common assumption was that we all were born with a fixed number of brain cells that die off as we get older. But that is not what happens,it is known that the brain continues to produce neurons through out the life cycle."(Jon Feingersh 2008)

Memory researcher D. Scott Small, says in the magazine article "Forgetting Is The New Normal" that "age goes up, memory goes down. Memory decline occurs in everyone."(Jon Feingersh 2008) Neuroscientist Fred Gage, from the Salk Institute, made the discovery that the adult brain continues to regenerate, those brains belonged to mice. Some of the mice had been sedentary, the other mice had been exercising, and the ones that had done the most exercises produced many more new neurons than the mice who were sedentary. Turns out humans can do the same thing.

A paper that was published in the Spring of 2007 said "a team who was led by Gage, Small, and Richard Sloan,who is a psychologist at Colombia University, revealed that after running an hour every day, four times a week for twelve weeks, men and women ages 21-45 showed increase in cerebral blood volume". So no matter what you eat, if you want to keep your memory sharp, you should go for a diet that keeps belly fat down.

Cerebral blood is not the only thing responsible for brain boosting, but exercise increases brain-derived neurontrophic, which is a protein that stimulates the birth of new brain cells, and helps them differentiate and connect. The magazine article "Forgetting is the new normal" also states that in a study more than 6,500 people who were overweight and had a large belly, were 2.3 times likely to have dementia as those with normal body weight and belly size"

(Jon Feingersh 2008). According to Jim Joseph, a neuroscientist with the U.S Department of Agriculture in Boston,blueberries zap free radicals, which are highly reactive atoms that can damage tissue, reverse aging, enhance cognition, and cause new neurons to grow.

The journal article " A Forty-Year Perspective" says that the remembrance of things past does require a specialized system involving the medial temptoral lobe and the hippocampus" (Eric R. Kandel 2009). "A forty-Year Perspective" also states "In 1968, Alden Spencer and Eric Kandel were invited to write a perspective for Physiological Reviews which they entitled “Cellular Neurophysiological Approaches in the Study of Learning.” In it they pointed out that there was no frame of reference for studying memory because they could not yet distinguish between the two conflicting approaches to the biology of memory." that had been advanced." (Eric R. Kandel 2009) The first behavioral systems to be analyzwere simple forms of learning in procedural memory.

From 1969 to 1979, several useful model systems emerged. The studies were aimed at showing the sites within a neural circuit that are modified by learning and memory storage, and specifying the cellular basis for those changes. Eric Kandel says "we knew less about procedural memory, a memory for perceptual and motor skills and other forms of non declarative memory that proved to involve not one but a number of brain systems, the cerebellum, the stratum, the amygdala, and in the most elementary instances, simple reflex pathways themselves knew even less about the mechanisms of any form of memory storage, we did not even know whether the storage mechanisms were synaptic or non synaptic".(Eric R. Kandel 2009)

The magazine article was very easy to understand, it had a lot of knowledge in it as well. although the journal article did contain a lot more information. But it was a little hard to follow along, it had a lot of dates and important people in it as well. The journal article used a lot of studies by a lot of different people as well,and a lot of comprehending. The magazine article gave more of a conclusion and a belief as opposed to the journal article. the Magazine stated studies but not as much as the journal did. There were also a lot of references to the journal article as well.

There are a lot of interesting details to learn from both articles and a lot of years people have spent trying to figure the human memory out, some conclusions might be correct, others might be false, but only time and more research is going to be able to say how the human mind and memory are used and what happens in retaining the information, and in loosing it. So maybe in another 40 years we will have more information to go on as well as the facts and opinions we have as of today.
