We hold on to different kinds of memories.
<ul>
<li>Short-term memories last seconds to hours and long-term memories last for years.</li>
<li>We also have a working memory, which allows us to keep something in mind for a limited time by repeating it.</li>
<li>Declarative memories are memories you experience consciously, like facts or &quot;common knowledge.&quot;</li>
<li>Nondeclaritive memory unconsciously builds up. These include procedural memories, such as riding a bicycle or playing the piano.</li>

The different kinds of memories

Health

By studying people with amnesia, it seems that short-term and long-term memories don&#39;t form in precisely the same way, nor do declarative and procedural memories. 
<ul>
<li>Emotional responses such as fear occur in a brain region called the amygdala.</li>
<li>Memories of learned skills are associated with the region called the striatum.</li>
<li>The hippocampus is essential for forming, retaining, and recalling declarative memories.</li>
<li>The temporal lobes play a critical role in forming and recalling memories.</li>
</ul>

Where your brain keeps memories

Memories are held within groups of neurons called cell assemblies. They fire as a group in response to a specific stimulus, such as recognising your friend&#39;s face. 
The more neurons fire together, the more the interconnection of the cells strengthen. We experience the nerves&#39; collective activity as a memory.

How we experience memories

For a short-term memory to become a long-term memory, it must be strengthened for long-term storage. The process is called memory consolidation and occurs using several processes.
Long-term potentiation consists of individual nerves changing themselves to grow and talk to their neighboring nerves differently. The remodeling modifies the nerve&#39;s connections, which makes the memory stable.

Memory consolidation

When we recall a memory, many parts of the brain share information, including regions that do high-level information processing, regions that deal with our senses&#39; new inputs, and the region that help coordinate the process, the medial temporal lobe.

Recalling a memory

Human memory happens in many parts of the brain at once, and some types of memories stick around longer than others.
