Brain's working Memory Tapped





This suddenly allows us to watch a memory been recorded and stored asit happens and before it is acted on to be set up in short termmemory or into long term memory. We even have a sense of how thebrain tells time or at least experiences the time decay of memory. Hell CMOS!
We have been tracking the slow and tortuous advances in ourunderstanding of brain functionality. At some point we will be ableto see information formed and recognized and ultimately deployedthrough the brain. It will be an awesome process. Once wellunderstood, we will also understand how specific genetic modificationcan augment that brain.
We certainly have strong indications that augmentation is practicedamong advanced space-faring societies but it could well be that weare expected to do it all ourselves anyway. Evolution may haveproduced the potential for augmentation but that took millions ofyears. We will not.
Scientists InventMethod to Create Memories in Brains

I find this extremelyhard to believe, but according to new research published in NatureNeuroscience, scientists have invented a method to induce memories inbrains for the first time in history.
Total Recall—here wecome.
The study—publishedby Case Western Reserve University School of Medicine's Professor ofNeurosciences and Physiology/Biophysics Ben Strowbridge, PhD, andMD/PhD student Robert A. Hyde—shows a method to store differenttypes of short-term memories, which they have successfully tested inbrain tissue stored in vitro.
Titled "MnemonicRepresentations of Transient Stimuli and Temporal Sequences in RodentHippocampus In Vitro", their paper describes how they used apiece of mouse brain tissue to form the necessary circuits to recorda short-term declarative memory. This type of memory can besomething like names, places and events.
These neuralcircuits—located in the hippocampus—retained the memory fromdifferent stimuli for ten seconds. The researchers were able toobserve the recording of these artificial memories by tracing theactivity of the brain cells. According to Hyde, "the type ofactivity we triggered in isolated brain sections was similar to whatother researchers have demonstrated in monkeys taught to performshort-term memory tasks. Both types of memory-related activitychanges typically lasted for 5-10 seconds."Uncanny. The rat brainin vitro was even able to remember different sequences of events.
The objective of thestudy is to better understand how short-term memories form in ourbrains. According to Doctor Strowbridge, "this is the first timeanyone has found a way to store information over seconds about bothtemporal sequences and stimulus patterns directly in brain tissue.This paves the way for future research to identify the specific braincircuits that allow us to form short-term memories." Theirresearch would also help in the fight against diseases likeAlzheimer's or Parkinson's disease.
