Um...What was I going to say?

I am sure many of you reading this know someone who is quite forgetful or maybe you are that person. I know I can be! The characteristic of being forgetful may become an idea of the past due to a recent study done Wake Forest University School of Medicine in North Carolina.

The experiment was performed on five primates. All of the primates had electrodes implanted into their pre-frontal cortex that were going to be used to help enhance their memory. The monkeys participated in a memory matching game where they had to pick the matching cards by using the computer mouse to point to it on the computer screen. While the monkeys were participating in the task, the actions of the layers in their prefrontal cortex was measured with the electrode. The layers of the cortex acted differently with the different tasks (picking the matching card and using the computer mouse to point to the correct match). 


The scientists then devised an algorithm that would allow the monkeys to complete the same task exactly how it was done the time before. This algorithm was sent to the electrode in the monkey's brain  and told the monkey's hand where to go. In a sense, it helped the monkey make up his/her mind.


Surprisingly, the electrodes interactions with the monkeys were not even interrupted when the monkeys were given cocaine. (Why they decided to give the monkeys cocaine...I don't know)

The research is still in its beginning stages but, it seems as if it is on the right track. There are high hopes that someday the electrodes placed in the prefrontal cortex may be able to help people that have suffered from differing brain injuries. I guess we will have to wait and see.

Hey Morgan.This does catch my eye when I saw the monkey.As I read through the description of the study,I did find certain points that they(or you perhaps) didn't make clear.First of all,if the stdy anchors on how electrodes implanted on the pre-frontal cortex of brain potentially enhance the primate's memory.You first said that different activities in the cortex had been detected when the monkey performed serial actions,but it turns out to me as an observational study as we many time have seem in psychological researches when we trace down minuscule changes in biological functionl parts and then pursue the correlations between the conditioned behavior and possible physiological changes with the body.I failed to see the point that the electrode indeed had HELPED the monkey with his faculty.Though in the following paragraph,scientists were said to transpose a pre-programmed algorithm to the monkey's pre-frontal cortex which is also the momentous processer in human's brain,it only "teaches" a scientific knowledge,as we see what algorithms does,then the proposal of recuperating brain injuries to me seems to be a far-fetched idea from this study,since the brain injuries are considered to be among the most brutal traumas of human kind,so it complicates various faculty impairments.Just by the virtue of electrodal signal,the recovery can hardly take place unless we find a systematic way to know how the stem cell works in the replication of deceased cell and go further to compose the script loading into the electrode to "teach",in this case,"spur" the proactive self-treatment in our brain to kick off.That'd be certainly a clinical miracle,so to speak.
