<p>Neurons are types of cells that can be programmed by us, by learning and repetition</p>
<ul>
<li>Neurons communicate through electricity and by releasing chemicals</li>
<li>The synapse is the interface between 2 neurons. The first neuron releases a chemical substance that is detected by the second, which then continues that electrical activity</li>
<li>Neuroplasticity - the more you practice something the more your brain changes. Every single neuron in the brain can form up to 10000 connections to other neurons. Those connections become more and more as we do something more and more</li>
</ul>
<p>Each neuron has a cell body with tiny branches called dendrites that receive information from other neurons. Extending from the cell body is long fibres called axons that send information to other neurons.</p>
<p>Since it is the connections between neurons that cause their mental capacities, it is not the number of cells that is important, but the number of potential connections between them</p>
<p>When a neuron fires an electrical impulse down the axon, the impulse is released as a chemical substance called a neurotransmitter. When this chemical reacts to a dendrite of another neuron, it triggers an electrical impulse. After, a series of chemical reactions begin.</p>
<ul>
<li>Another neurotransmitter is serotonin. Serotonin is linked with mood and emotion. Too much stress can lead to low levels of serotonin, and low levels are associated with anxiety and depression.</li>
</ul>

thoughts-on


Welcome to my Second Brain! Here you'll find thoughts, lessons, facts and any other interesting musings that I've come across or thought up over the years. A lot of what I have gathered is originally from the minds of others, while some of it originates from myself. Some notes may contain misinformation, though I try to be rigorous with my additions.

What I have here does not necessarily reflect my thoughts and views. I collect information not based upon whether I agree with it or not, but rather when I determine it to contain some value that can be served in the future.  

You can think of this collection of inter-linked notes as my personal wiki.

This Dendron notebook is the sister vault to the tech-focused [Digital Garden](https://tech.kyletycholiz.com)

## Tags
Throughout the Second Brain, I have made use of tags, which give semantic meaning to the pieces of information.

- `ex.` - Denotes an *example* of the preceding piece of information
- `spec:` - Specifies that the preceding information has some degree of *speculation* to it, and may not be 100% factual. Ideally this gets clarified over time as my understanding develops. I try to go back after I have better understood the topic and clear out the notes of `spec:` tags
- `anal:` - Denotes an *analogy* of the preceding information. When I can, I attempt to link concepts to others that I have previously learned.
- `mn:` - Denotes a *mnemonic* to aid in memorization
- `expl:` - Denotes an *explanation*

## Resources
### UE (Unexamined) Resources
Often, I come across sources of information that I believe to be high-quality. They may be recommendations or found in some other way. No matter their origin, I may be in a position where I don't have the time to fully examine them (and properly extract notes), or I may not require the information at that moment in time. In cases like these, I will add reference to a section of the note called **UE Resources**. The idea is that in the future when I am ready to examine them, I have a list of resources that I can start with. This is an alternative approach to compiling browser bookmarks, which I've found can quickly become untenable.

### E (Examined) Resources
Once a resource has been thoroughly examined and has been mined for notes, it will be moved from *UE Resources* to *E Resources*. This is to indicate that (in my own estimation), there is nothing more to be gained from the resource that is not already in the note.

### Resources
This heading is for inexhaustible resources. 
- A prime example would be a quality website that continually posts articles- another example would be a tool, such as software that measures frequencies in a room to help acoustically treat it.
