We all
need a proper amount of sleep to function throughout the day.  When we have enough sleep we can improve the
brains memory and enhance learning. When we don’t get enough sleep we are bound
to make mistakes and become less productive in the daily
things we do. While we sleep our brain in processing information from that day
and its forming memories.

Sleep can cause changes in the brain that holds memories and
strengthens our brain cells connections. It also sends information from one
brain region to another. While we sleep our brain replays the memories of our
day, and helps to organize the order in which those things occurred. The things
you learn and see stay in your brain during sleep and the human brain will
store the important information and delete the non-important information.  Scientist believes that while we sleep our
memories get moved to a better and permanent brain region, making more space
for the next day. While we sleep our brain chooses and enhances the memories
that are most important to you and it downgrades the memories that aren’t as

Sleeping shortly after learning something new has been shown
to help remember better. Research shows that when we learn before sleeping or
napping we will remember the information better. Sleep also helps us make more
ideas and not just remember the old ones. One of the earliest researches on
sleep and memory was on declarative memory.

In a study, some individuals participated in a language
course and were shown to have an increase in REM (rapid-eye movement). This
stage of sleep is when dreaming mostly happens. Scientist believe that REM
sleep had an essential role in what was learned.

Memory is the power where the mind stores and remembers
information. There are three stages in memory. The first stage is encoding
memory, it allows the item being seen and being interested in to be made into
an idea that can be stored within the brain to be remembered later. The next
stage is consolidation, in this stage it maintains, strengthens, and modifies
memories that are kept in your memory. Once our memories go through this process
they are considered stable. The last stage of memory is retrieval. In this
stage events and information from the past are accessed again, which were
previously stored in the brain, is known as remembering.

Scientist believe that during sleep the hippocampus, a small
region of the brain that part of a system associated with memory, replays the
events from that day for the neocortex, where it will review and process
memories, helping them last longer. Procedural memory is a part of long-term
memory and is responsible for knowing how to do things.

A lack of sleep can cause memory loss and forgetfulness. Not
getting enough sleep can cause brain deterioration. Researchers have seen that
during sleep some important brain waves are made, which play an important role
in storing memories. The brain waves will transfer our memories from the
hippocampus to the prefrontal cortex, where long term memories are formed.     

Sleep and memory are closely related because without sleep
we wouldn’t be able to remember most things that we do throughout the day.
During sleep our brain categorizes our memories and makes it easier for us to
remember things. Without sleep we wouldn’t remember over half of the things
that we do.
