A new study has disclosed that long talks on cell phones can have adverse effect on memory.

The scientists from the Division of Neurosurgery, Lund University, in Sweden discovered that microwave radiation from mobile phones could have an effect on the so-called blood-brain barrier.

The researchers conducted a study on rats and found that rats exposed to cellphone radiation for two hours every week for more than a year had poorer results on a memory test as compared to the control group that hadn’t been exposed to mobile rays.

The rats were released into a box with four objects mounted in it. The objects were different on two occasions, and their position was also altered each time.

The authentic test trial was the third occasion in which the rats found two objects from the first occasion and two from the second.

Lead researcher Henrietta Nittby found that the control rats spent more time exploring the objects from the first occasion, which they considered more exciting since they had not seen them for some time.

On the other hand, the experiment rats showed a lesser pronounced difference in interest.

In another study carried by Leif Salford have previously found that albumin, a protein that function as a transport molecule in the blood, leaks out into brain tissue when lab animals are exposed to cell phone radiation.

The research team also found certain nerve damage in the form of damaged nerve cells in the cerebral cortex and in the hippocampus, the memory center of the brain.

Henrietta Nittby said, “We now see that things happen to the brains of lab animals after cell phone radiation. The next step is to try to understand why this happens.”
