All right the fifth part of this course how to improve your memory and we will start by diving deeper
into how memories are stored and retrieved in the human brain.
The most basic level memories are stored as microscopic chemical changes are the connection points between
neurons in the brain the brain has possibly one hundred billion neurons each of which connects to up
to 10000 average near us.
By some estimates there are over 100 trillion total connection points or says.
And the human brain as information flows through the neural circuits and networks of the brain the activity
of the neurons causes the connection points to become stronger or weaker in response the strengthening
and weakening of the sinuses is how your brain stores information.
This mechanism is called long term potency Asian or EL-TIBI from here the story becomes way more complex.
The hippocampus is a region of the brain that is specialized to codifying and structuring memories particularly
autobiographical and episodic memories such as memories about people places events.
However some scientists believe that memories are only held in the Heibel campus temporary and are later
recorded and dispersed for all the rest of the brain using a process called memory consolidation which
may happen during your sleep.
The precise way that long term memories are structured and represented across brilliance of sign ups
this is the subject of intense ongoing research and remains still one of the great mysteries of neuroscience.
Now short term memory appears to work completely differently.
A phone number can be remembered instantly but forgotten just as fast repetition of experience such
as reciting a phone number is one of the many ways that memories migrate from short memory to longer
term systems.
The most popular view on short term memory is that it results from signaling patterns circulating in
recurrent feedback loops within neural circuits.
On the scale of a 1 millimeter or so of brain tissue.
But this too is the subject of ongoing research.
In conclusion memory is one of the most fascinating subfields of neuroscience and the study of memory
is still in its infancy.
An important question is how are memories coded by neurons.
The models that exist today are still very primitive.
All right we've done with the fury part of this module.
In the next lesson we are going into practicality.
How does the brain decide which memories to store.
See you there.
