HOW DOES YOUR MEMORY WORK
Memory is not only sorted information we recall when we want. Actually, it is a journey from the present to the past, and for this reason the BBC displayed an amazing broadcast. The video is about different conditions and diseases affect the ability to remember. The video graduated from children’s ability to remember until finished with Alzheimer’s disease.
First experiment was done by Professor Mark Howe, the purpose of it was to observe children’s ability to recognize themselves on a mirror.

In the near future we may have a medication help people with posttraumatic stress disorder (PTSD) by erasing all that sad moments.
Many changes happen to the human body as we become older. In addition, many changes also happen to the brain. Professor Randy Buckner found that the white matter in the brain decreases with aging. Next, the video showed the story of John...
