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. "Because intelligence is such a broad construct, you can't really track it back to one part of the brain," says Duje Tadin, a senior author on the study and an assistant professor of brain and cognitive sciences at the University of Rochester.
"But since this task is so simple and so closely linked to IQ, it may give us clues about what makes a brain more efficient, and, consequently, more intelligent. " Test yourself: Thinking Cap. 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. 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.

Neuron. 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... Covering technological, scientific, and cultural trends that are changing human beings in fundamental ways. 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.” Neuron Connectivity. A selection of articles related to neuron connectivity.

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. Dendrite - Is the tree branch like structure connected to the nerve cell body (soma) that sends and receives information between cells.
