Memory

Ever felt that your brain capability is exhausted and there is no space for new information to store? Well it is not weird, this is a common expression that most of the people experience on daily basis. In order to clear the doubts, researchers in recent past studied the mechanism and found out that the brain never literally fills up, but at times it replaces old memory with new ones.

Recently, to find more on the given subject, a team of researchers at Scripps Research has successfully been able to display the physical mechanism of forming a memory and later how it is replaced. The study was published in Cell Reports and stated that the research was done on fruit flies. They found that a single dopamine neuron has the ability to drive both the forgetting and learning process.

Researchers Study Memory in Flies

In order to study memories in flies, researchers try to make a particular odor familiar to flies with an electric shock. Once researchers believed the flies were associated with the odor, they observed that the insect tend to avoid that particular odor. This confirmed that the memory is formed.

Rapid advancement in technology helps investigators use imaging techniques to look at the whole process. Researchers found out that when behavioral memory degrades, the changes that were made by cells during learning is completely reversed
