Cerebral Atrophy

A place to expose the fruits of neural networks; a virtual environment to catalog the proprietor's taste and to document the effects social hazards, nature, math and Nutella have on his mental sanity.

Inflating a set of cat lungs

Lungs are by most accounts mundane. Everybody has them, few give it much thought. But sequestered within darkness of the chest cavity, enveloping the fluttering heart, there’s a incredible wonder to this oddly inflatable organ.

Dissection is a destructive process. Rudely excised from membranous mooring and nourishing vessels, the deflated lungs appear little more than bloodied meat; amorphous and exposed…….until a breath of air unfurls its secret glory. 

Here, a set of cat lungs is inflated with a straw. Comprised of hundreds of millions of microscopic air sacks called aveoli, Mammalian lungs harbor air capacity that is difficult to believe unless seen. The color of the entire organ lightens into a soft pink, as each microscopic sac fills with air.

A debt of gratitude is owed to cyborgraptor for her assistance in creating these gifs, as well as the students that help me film this demo. 

Public service announcement: You essentially have balloons inside your chest. There’s some really great anatomy GIFs and images on that blog, too.

The more I learn of how we we function, the more amazed that we do at all.

The definitive guide to embedding source code in tumblr

A guide written by a noob for noobs on how to embed code snippets in tumblr text posts. (work in progress)

There are several ways to embed code in a text post. Here I present what I believe are the two easiest ways. First, I present the google-code-prettify method which I believe is good for general purposes and looks good. It is also customizable, especially if you know CSS (which I currently don’t). Then I show a very easy (but uglier IMO) method using Github’s gists. In several parts I’ll point you to places where there is Tumblr code (html) and CSS code, do not be scared, you probably won’t break anything.

Google Code Prettify

First, you must set up the ability to post code.

Step 1: Go to the customize option of your tumblr.

Step 2: Click on the Edit HTML button.

Step 3: Paste this   <script src=”https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js”></script> one line after the “<head>”. Don’t erase anything :)

Done.

Was it really that easy? Yes. Now, to post code, inside a text post:

Step 1: click the “<html>” button on the editing toolbar.

Step 2: where you want your code write <pre class=”prettyprint”> (your code here) </pre>

Done. But it doesn’t look very nice.

To make it nicer, you can choose a theme in this website. Copy and paste the code to your favorite programming text editor (i.e. not word).

What you are seeing is in CSS. If you know CSS, do as you will. For this example, I chose the Sunburst theme because it’s nice and because others (like original) are a little more tedious to edit.

pre .str, code .str { font-size: 135% ; color: #65B042; } /* string  - green */
pre .kwd, code .kwd { font-size: 135%; color: #E28964; } /* keyword - dark pink */
pre .com, code .com { font-size: 135%; color: #AEAEAE; font-style: italic; } /* comment - gray */
pre .typ, code .typ { font-size: 135%; color: #89bdff; } /* type - light blue */
pre .lit, code .lit { font-size: 135%; color: #3387CC; } /* literal - blue */
pre .pun, code .pun { font-size: 135%; color: #678CB1; } /* punctuation - white */
pre .pln, code .pln { font-size: 135%; color: #fff; } /* plaintext - white */
pre .tag, code .tag { font-size: 135%; color: #89bdff; } /* html/xml tag    - light blue */
pre .atn, code .atn { font-size: 135%; color: #bdb76b; } /* html/xml attribute name  - khaki */
pre .atv, code .atv { font-size: 135%; color: #65B042; } /* html/xml attribute value - green */
pre .dec, code .dec { font-size: 135%; color: #3387CC; } /* decimal - blue */ 

 This first part is responsible for the actual font of the text. In my code, I wanted the font a bit bigger so I added the command “font-size:” and set all to 135%. You must follow each command by a semicolon “;”. The color: command is followed by a pound # and a hexadecimal value that represents a color. There are many color pickers and palettes online, try searching for “hexadecimal color picker” and copy the corresponding hexadecimal code after the ‘#’ symbol. Again, add a ‘;’ to the end. The parts that have ‘*/ text */ are comments that describe what piece of text you are changing.

pre.prettyprint, code.prettyprint {
        background-color: #000;
        -moz-border-radius: 6px;
        -webkit-border-radius: 6px;
        -o-border-radius: 6px;
        -ms-border-radius: 6px;
        -khtml-border-radius: 6px;
        border-radius: 6px;
}
pre.prettyprint {
        width: 100%;
        margin: 1em auto;
        padding: 1em;
        white-space: pre-wrap;
}    

stay tuned! work in progress…

Testing source code post

Header

This code uses STL lists to input names and sort them alphabetically. The sort function (mylist.sort()) takes as parameter a strict weak ordering function to make the sort case insensitive. Code is in spanish and english (fyi palabra=word).

source

    bool comp(const string& one, const string& two){
    for(unsigned int j=0; j<one.length() && j<two.length(); j++){
		if (tolower(one[j]) < tolower(two[j])) 
			return true;
		else if (tolower(one[j]) > tolower(two[j]))
			return false;
	}
	if (one.length()<two.length())
		return true;
	return false;
}

We do not just self engineer better worlds to think in. We self-engineer ourselves to think and perform better in the worlds we find ourselves in. We self-engineer worlds in which to build better worlds to think in. We build better tools to think with and use these very tools to discover still better tools to think with. We tune the way we use these tools by building educational practices to train ourselves to use our best cognitive tools better

When brain size increases, what is increasing is the number of neurons, their connections, and the space between the neurons. The finding that the human cerebral cortex volume is 2.75 times larger than in chimpanzees, but has only 1.25 times more neurons intimates that a good deal of the increased mass is due to the space between cell bodies and what that space is filled with. The space, known as neuropil, is filled with the stuff that connections are made of: axons, dendrites, and synapses. In general, the larger the area, the better connected it is, as more neurons connect to more and more other neurons.
