Motion quotient: IQ predicted by ability to filter visual motion Motion quotient: IQ predicted by ability to filter visual motion May 23, 2013 — A brief visual task can predict IQ, according to a new study. This surprisingly simple exercise measures the brain's unconscious ability to filter out visual movement. The study shows that individuals whose brains are better at automatically suppressing background motion perform better on standard measures of intelligence. The test is the first purely sensory assessment to be strongly correlated with IQ and may provide a non-verbal and culturally unbiased tool for scientists seeking to understand neural processes associated with general intelligence.
Alternatives: An alternative to finding electrodes and doing all the amplification DIY-style, it's now possible to purchase a single channel off-the-shelf headset from Neurosky which sends the raw EEG via bluetooth. In addition to potentially being easier to set up and using dry electrodes, this system also ensures user safety by removing the user from any possible shock hazards associated with being attached to wall power. The major drawback is that it has only a single channel, but maybe this will improve in the next version. Emotiv has a headset with many channels, but they are currently not as DIY friendly due to the fact they will not allow users access to raw EEG data, but only to their processed data. Maybe we need some pressure from the DIY community here or someone to reverse engineer their processor. Thinking Cap Thinking Cap
Your Brain Your Brain David L. Goldin, J.D., M.B.A. © 2013 Late in his career, Francis Crick, the Nobel laureate who was one of the co-discoverers of the molecular structure of DNA, announced what he called his "astonishing hypothesis" of the brain and mind: "You, your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules." Others have since commented on Dr. Crick's hypothesis, some of whom, such as the evolutionary biologist Edwin O. Wilson, describe a genetic basis for a predisposition to religious belief.

Fun Facts About Neurons Fun Facts About Neurons Here are some interesting statistics* about neurons in humans and other animals (remember that these are averages because there is a lot of variability in the nervous system!): Average number of neurons in the human brain = 100 billionAverage number of neurons in the octopus brain = 300 millionRate of neuron growth during fetal development in utero = 250,000 neurons/minuteDiameter of a neuron = 4 to 100 micronsLength of giraffe primary afferent axon (from neck to toe) = 15 feetVelocity of signal transmitted through a neuron = 1.2 to 250 miles/hourThere are as many neurons in the human brain as stars in the Milky WayThe number of ways information travels in the human brain is greater than the number of stars in the universe What if we lined up all the neurons in our body?

Your brain is involved with everything you do. How you think, how you feel, how you act, and how well you get along with other people has to do with the moment-by-moment functioning of your brain. After looking at thousands and thousands of brain scans I have come to realize that how your brain functions influences the kind of therapist you are, the effectiveness of your mothering skill and how well you do in business. Are you the kind of therapist that is on time, listens, and is generally helpful? Likely, your frontal lobes work right. The Amen Clinics The Amen Clinics
More brain connections than stars in the universe? No, not even close. « The Neural Spark More brain connections than stars in the universe? No, not even close. « The Neural Spark Our observable universe is huge. Make that really huge. So if you have ever read that our brain connections outnumber the stars in the universe (perhaps here or from this book), I hope you frowned in skepticism.

A neuron is an electrically Electricity is a general term encompassing a variety of phenomena resulting from the presence and flow of electric charge. These include many easily recognizable phenomena, such as lightning, static electricity, and the flow of electrical current in an electrical wire... The cell is the basic structural and functional unit of all known living organisms. Neuron Neuron
Surfdaddy Orca March 30, 2010 The memristor — the so-called “missing link of electronics” memory technology that can change its resistance in varying levels — has been around on paper for nearly 40 years. However it wasn’t until 2010 that a group at the University of Michigan led by Dr. Wei Lu demonstrated that it can be used to build brain-like computers in a paper just published in Nano Letters. New Scientist reports that “memristors can behave uncannily like the junctions between neurons in the brain.” h+ Magazine | Covering technological, scientific, and cultural trends that are changing human beings in fundamental ways.

More Group Mind Basics (GM2) The similarities between the function of a two-way radio and the human body can be quite surprising. The body/mind constantly emits all aspects of our internal state to the environment, and in turn receives inputs from the world in the same manner.

How Your Brain Works" Neurons come in many sizes. For example, a single sensory neuron from your fingertip has an axon that extends the length of your arm, while neurons within the brain may extend only a few millimeters. They also have different shapes depending on their functions. Motor neurons that control muscle contractions have a cell body on one end, a long axon in the middle and dendrites on the other end. Sensory neurons have dendrites on both ends, connected by a long axon with a cell body in the middle. Interneurons, or associative neurons, carry information between motor and sensory neurons.
Neuroplasticity Terms Illustration of neurons firing Neuron - A neuron is the functioning cell unit in the nervous system that is also known as a nerve cell. Neurons are responsible for sending impulse messages to other neural cells. Impulse messages in a neuron are sent via the release of neurotransmitters. The neuron's cell body is called the soma. The neuron cell consists of 3 main sections a soma, axon, dendrite.
