Brain Atlas - Introduction
The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. It covers the nuclei deep within the cerebral hemisphere e.g. the basal ganglia; the structure called the thalamus, and the ‘white matter’, which consists mostly of myelinated axons. – closely packed neuron cell bodies form the grey matter of the brain.
10 Ways to Alter Your Consciousness Without Drugs
I'm typically not one for altered states of consciousness. I don't do drugs. I've never been drunk.
The Singularity is Far: A Neuroscientist's View
David J. Linden is the author of a new book,The Compass of Pleasure: How Our Brains Make Fatty Foods, Orgasm, Exercise, Marijuana, Generosity, Vodka, Learning, and Gambling Feel So Good. He is a professor of neuroscience at The Johns Hopkins University School of Medicine and Chief Editor of the Journal of Neurophysiology. Ray Kurzweil, the prominent inventor and futurist, can't wait to get nanobots into his brain.

This book is an introduction to the standard methods of proving mathematical theorems. It has been approved by the American Institute of Mathematics' Open Textbook Initiative. Also see the Mathematical Association of America Math DL review (of the 1st edition), and the Amazon reviews.
Neuron
All neurons are electrically excitable, maintaining voltage gradients across their membranes by means of metabolically driven ion pumps, which combine with ion channels embedded in the membrane to generate intracellular-versus-extracellular concentration differences of ions such as sodium, potassium, chloride, and calcium. Changes in the cross-membrane voltage can alter the function of voltage-dependent ion channels. If the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives. Neurons do not undergo cell division. In most cases, neurons are generated by special types of stem cells.
Upside-down glasses
If you just want to get yourself a pair of perspective flipping goggles, all you have to do is download the file, arrange the parts to be cut (being sure to include two earpieces, they're identical, you know) and laser cut yourself a pair (mirror side down on the plastic, please.) It's pretty simple. What those of you without laser cutters (poor souls that you are) may take away is this cool construction method I learned from puzzle maker Lee Krasnow. I measured my screws, nuts, and washers, and modeled them simply in cad. I measured the width of my plexiglass.
The Brain: A Body Fit for a Freaky-Big Brain
Aiello and Wheeler noted that this dramatic increase in brain size would seem to have required a dramatic increase in metabolism—the same way that adding an air-conditioning system to a house would increase the electricity bill. Yet humans burn the same number of calories, scaled to size, as other primates. Somehow, Aiello and Wheeler argued, our ancestors found a way to balance their energy budget. As they expanded their brains, perhaps they slimmed down other organs.
47 Mind-Blowing Psychology-Proven Facts You Should Know About Yourself
I’ve decided to start a series called 100 Things You Should Know about People. As in: 100 things you should know if you are going to design an effective and persuasive website, web application or software application. Or maybe just 100 things that everyone should know about humans! The order that I’ll present these 100 things is going to be pretty random. So the fact that this first one is first doesn’t mean that’s it’s the most important.. just that it came to mind first.
Making Sense of the World, Several Senses at a Time
Our five senses–sight, hearing, touch, taste and smell–seem to operate independently, as five distinct modes of perceiving the world. In reality, however, they collaborate closely to enable the mind to better understand its surroundings. We can become aware of this collaboration under special circumstances. In some cases, a sense may covertly influence the one we think is dominant.
Architects of Control, Program One – Mass Control & The Future of Mankind
“The real war is the war on consciousness. It’s very important to always remember that …Mind control is ubiquitous. It’s almost a question of who is not mind controlled, as opposed to who is mind controlled. It’s just a difference in degree. The whole question of what is consciousness and how it can be manipulated is one of the most crucial questions of our time.” Produced by Michael Tsarion and Blue Fire Film, Architects of Control: Program One, explores humankind’s future and the posthuman world.
