The proliferation of new neurons is astounding,&nbsp;but&nbsp;as we get older, this capacity decreases.Nevertheless,&nbsp;neurogenesis &nbsp;continues even when we get older. The old belief that we’re born with a determined number of neurons, and that throughout life we do nothing more than lose them, is false.&nbsp;There is a decline in neuroplasticity, but the brain continues to be considerably malleable.

Learning throughout life

First of all, it’s best to have&nbsp;an enriching environment that challenges the mind. Second of all, it’s known that moderate exercise also favors neuroplasticity. On the other hand, old age, chronic stress, and certain blood components seem to impair&nbsp;it. Neurogenesis in the hippocampus can be stimulated when we learn new things.

Factors that can influence neuroplasticity

Neuroplasticity is the mechanism that produces learning. Each person’s capacity for learning is determined both by genetics and by education.&nbsp;For example, each person’s&nbsp;IQ&nbsp;will, for the most part, be determined by genetics, but intellectual effort can also affect&nbsp;the plasticity of the brain and one’s&nbsp;abilities.Even if you have a genetic predisposition for learning, it will be nothing more than potential if you don’t know how to develop it. If you don’t use it, not only are you not&nbsp;developing it, but&nbsp;you’ll&nbsp;also lose the possibility of doing so.

What happens in the brain when we learn? 

Neuroplasticity is at its greatest during childhood, as the brain is more flexible and it constantly receives new stimuli. During this time, a large number

It's fascinating to know that the Human Brain knows how to carry out different scientific processes from birth even though we consciously neither feel it nor understand it unless we are taught about it.For Instance-1)Our Brain knows from birth that it has to invert the image formed in the retina to get the actual image but we know it only when we get to Higher classes.2)The Brain projects back the light rays that form the image at the retina in a straight line to know the Light Source even though 'we' don't know initially that light travels in straight line.

Focusing:<ul><li>concentrating intently on sth you're trying to learn</li><li>sth you're rather familiar with -&gt; thought moves smoothly as if it's traveling along a familiar, nicely paved road</li></ul>Diffuse thinking:<ul><li>more relaxed, related to a set of neural resting states</li><li>for new ideas/ approaches</li><li>looking at things broadly from a big picture perspective -&gt; making new neural connections &amp; pathways</li><li>it’s not for problem solving/finest aspects of sth, but&nbsp;for getting to the initial place you need to be in to home in on a solution</li></ul>Each helps us to learn, but you can't be in both modes at the same time.

Focused & Diffuse Modes - two modes of thinking

<ul><li>Relaxed in a chair, letting his mind go free, often still vaguely thinking about what he had been previously focusing on</li><li>A key in his hand, dangling it just above the floor</li><li>As he would fall asleep, the key would fall from his hand waking him up, just in time so he could gather up those diffuse mode connections &amp; ideas</li><li>Then going back into the focused mode, he‘d build on these connections</li></ul>

Salvador Dali’s Technique to Be Creative 

Thomas Edison used the same technique as Dali, only with a ball.When you're learning something new, especially something that's a little more difficult, your mind needs to be able to go back and forth between the 2 different learning modes. That's what helps you learn effectively. To gain muscular structure, you need to do a little work every day, gradually allowing your muscles to grow.Similarly, to build neuro-structure, you need to do the same. A little work every day, gradually allowing yourself to grow. That’s the trick.

Switching Between The Two Learning Modes 

Neurons become linked together through repeated use. The more abstract sth is, the more important it’s to practice to bring those ideas into reality for you.<ul><li>If you first begin to understand sth, e.g. how to solve a problem, the neural pattern is very weak -&gt; a faint pattern</li><li>Solving it again without solution deepens that neuron pattern&nbsp;(darker pattern)</li><li>Going over each step in your mind &amp; practicing on related problems -&gt; dark pattern</li></ul>Practice makes permanent.<ul><li>enriched environment (people around us instead of isolation) &amp; excising creates new neurons -&gt; helps learning + memory</li></ul>

Build & Strengthen Your Neurons

<ul><li>what you're immediately &amp; consciously processing in your mind</li><li>through its connections to other parts of your brain, you can access long term memories</li><li>holds only about 4 chunks of information (researchers said 7 in the past)</li><li>We group memory items into chunks, to make our working memory bigger than it actually is</li></ul>

Working Memory

<ul><li>like a storage warehouse</li><li>it's where you store fundamental concepts &amp; techniques that are often involved in whatever you're learning about</li><li>When you encounter sth new, you often use your working memory to handle it. If you want to move that information into your long term memory, it takes time and practice.&nbsp;You need to repeat it at least a few times or it can be difficult for you to find it later when you might need it.</li></ul>

Long Term Memory

<ul><li>repeat what you're trying to retain, but space this repetition out -&gt; e.g. practice a new voc. word/ a problem solving technique over several days</li><li>Research: if you repeat sth 20times in one evening, you won’t remember nearly as well as if you practice it 20x over several days.&nbsp;</li><li>Like building a brick wall: If you don't leave time for the mortar to dry, that is, time for the synoptic connections to form and strengthen, you won't have a very good structure.&nbsp;</li></ul>

Spaced Repetition 

Metabolic toxins in your brain-&gt; Sleep helps to wash away them, keeps the brain clean &amp; healthyToo little sleep makes you do worse on tests (you can't think clearly)Over too long of a time: headaches, depression, heart disease, diabetes, aging/ dying earlierSleep: <ul><li>important for memory &amp; learning process</li><li>organizing ideas &amp; concepts</li><li>strengthens neural patterns</li><li>improved problem solving &amp; understanding skills</li></ul>Repeat what you want to learn (focused mode) right before you sleep (diffuse m.) + set in mind to dream about it -&gt; increased chance of dreaming -&gt; better understanding

The Importance of Sleep in Learning

= pieces of information bound together through meaning/ useThe new logical whole makes the chunk easier to remember &amp; also makes easier to fit it into the “larger picture”.Just memorizing a fact without understanding is not enough, you have to find a place for it.How does it work?<ol><li>Focused practice + repetition (4 slots of working memory make connections to informations of your brain, when you’re angry/stressed/ afraid-&gt;less of those connections)</li><li>Creation of chunks</li><li>Small chunks becomes larger</li><li>As you gradually become a master of the material, you’ll have more creative interpretations of it</li></ol>

What is a Chunk?

The best chunks are so well ingrained, that you don't even have to consciously think about it.&nbsp;When you're learning new math/science material:<ul><li>Undivided attention. Let your brain focus on chunking.Leave free the limited slots in working memory</li><li>Understand the main idea/connection bw. the basic elements. Start with an example with solution</li><li>Figure out why the steps are taken the way they are. See the key features. Underline principles of a problem</li><li>Concern:it can be all too easy to focus too much on why an individual step works &amp; not on why this particular step’s the next thing you should do!</li></ul>

How to Form a Chunk?

Can you create a chunk if you don't understand? Yes, but it's often a useless chunk that won't fit in with other materials.&nbsp;Just understanding how a problem was solved doesn’t necessarily create a chunk that you can easily remember later. Don't confuse the "Aha!" of a breakthrough in understanding, with solid expertise.Math/science:<ul><li>review it soon after you first learned it</li><li>close the book &amp; test yourself </li><li>solving the problem speeds up your learning. Seeing/ understanding it doesn't mean that you can actually do it. Doing it yourself helps create the patterns</li></ul>

How to Form a Chunk? - Part2

Gain context to see not just how, but also when to use this chunk!How to start with a new topic?<ol><li>Do a 2min. picture walk through a chapter (glancing at pictures &amp; section headings allows you to gain a sense of the big picture to see where it fits in)</li><li>Begin studying it:Learn the major concepts first, then fill in the details</li><li>Go beyond the initial problem, see more broadly. Repeat &amp; practice with both related &amp; unrelated problems</li></ol><ul><li>to see not only when to use the chunk, but when not,</li><li>to build &amp; strengthen each chunk, so you can easily access it whenever you need to</li></ul>

Inspirational Quote From  Scientist

Plasticity is the ability of the brain to change. Capacity of neurons and neural networks in the brain to change their connections and behaviour in response to new information, sensory stimulation, development, damage or dysfunction.Of course, the brain is made up of about 100 billion neurons, each with thousands of synapses.The organisation of these connections encodes your beliefs, memories, habits, behaviours, and more. From birth, this organisation constantly changes – the exciting aspect of this is that we can purposefully change our neural organisation through directed effort.

What is Neuroplasticity? 

When new neurons are born from stem cells within the brain, which can then form new circuits. Neurogenesis surprisingly only happens in a few areas in the brain. One area is the hippocampus which needs a lot of new neurons because it encodes new memories. Another area is the olfactory bulb, which allows us to sense smells.Contrast this with the prefrontal cortex. Sitting at the front of your brain, the prefrontal cortex is what performs high level abstraction and ‘smart’ thinking. Interestingly, the prefrontal cortex is not capable of neurogenesis.
