The more you sleep, the better your memory becomes!

Brought to you by Katherine Beach - Link is next to the title. It's a nice little summary of some of the things I have been telling you.
Memory
"There are three different types of memory: sensory, short term, and long term. Sensory memory is the ability to retain information after looking at something for only a moment. If something is viewed for only 200-500 milliseconds, what you perceive is sensory memory. Short term memory is the next step up from sensory. Some sensory memories are transferred to short term memories. If something is viewed for a few seconds all the way up to a minute, then it falls under the category of short-term memory. The amount of information that can be stored in sensory and short term memory is extremely limited. Many memories are transferred to long term memory, which holds the memories of a person’s life span. The more a person sleeps, the better the memory becomes, because during sleep a part of the brain called the hippocampus replays events from the day.
For a memory to transfer from sensory to short term attention is required. The brain must determine whether a piece of information is necessary and useful. If it is then the memory goes from sensory to working. Short term memory is the bridge between sensory and long term memory. Memories are carried like items on a conveyor belt through short term memory to long term, but the amount of memories that get through is limited. Short term memory is said to hold 7 /- 2 pieces of information. For example, if a person were to look at 9 letters for 30 sec to a minute, they would be able to remember about 7 of them. The letters that were retained in the short term memory will only last for about 15-30 seconds, when they will either be forgotten or encoded into the long term memory".
So don't go short on sleep, I know many of you do.
