Watch the video above, the trick is nothing short of incredible!

This is due to a mechanism called the opponent-process theory, which was developed in the 1870s. It is the idea of perceiving color in terms of paired opposites such as red with green, and yellow with blue. The possible scientific explanation for this theory is that bipolar cells are excited by one set of wavelengths and inhibited by other, which are in extend attached to the cone retinal receptors.

A landmark study, based on genetic analysis of nearly 65,000 people, has revealed that a person's risk of schizophrenia is increased if they inherit specific variants in a gene related to "synaptic pruning" - the elimination of connections between neurons. The findings represent the first time that the origin of this devastating psychiatric disease has been causally linked to specific gene variants and a biological process. They also help explain decades-old observations: synaptic pruning is particularly active during adolescence, which is the typical period of onset for schizophrenia symptoms, and brains of schizophrenic patients tend to show fewer connections between neurons. The gene, called component 4 (C4), plays a well-known role in t ...

After a broken neck left him quadriplegic, Ian Burkhart was told he would never be able to use his hands. Now he can grasp a bottle and pick up a credit card by using a computer plugged directly into his brain. Special software is able to decode his thoughts and convert them into electrical signals in his hand, bypassing the damaged nerves in his spine. Now Ian has regained an amazing degree of control over his hand, each movement stimulated by his own thoughts.

According to a study published in the medical journal eLife, researchers found that specific combinations of gut bacteria produce substances that affect myelin content and cause social avoidance behaviors in mice.

Researchers transferred fecal bacteria from the gut of depressed mice to genetically distinct mice exhibiting non-depressed behavior. The study showed that the transfer of microbiota was sufficient to induce social withdrawal behaviors and change the expression of myelin genes and myelin content in the brains of the recipient mice.

In an effort to define the mechanism of gut-brain communication, researchers identified bacterial communities associated with increased levels of cresol, a substance that has the ability to pass the bloo ...

Lysergic acid diethylamide (LSD) is a recreational, psychedelic drug that alter awareness of the surroundings, perceptions, and feelings, as well as sensations and images that seem real though they are not.

LSD works by binding primarily to the dopamine receptors and adrenal receptors in the brain. It also binds to most of the serotonin receptors. The binding process is believed to overstimulate the natural neurotransmission process, activating the receptors and altering thought and perceptions.

Though medical researchers have not scientifically proven how this process alters consciousness, they are certain about the binding process which links hallucinogenic chemicals to receptors and disrupts neurotransmission between receptors and parts of ...

Why studying for large chunks of time can be counter-productive

We’ve all had those days where no matter what good fortune comes our way in the morning or afternoon, we still walk around with a slight furrow in our brow knowing that a night chock-full of homework and studying awaits. It’s like a Utah Jazz fan watching the wildly entertaining 1997 NBA Finals on ESPN Classic – he or she might enjoy it for awhile, but in the back of their mind they know the Michael Jordan buzz saw is coming to ruin their hopes and dreams. (Too young to remember? That's fine, you get the point...)

Alright, so maybe Michael Jordan draining threes isn’t exactly the same as laboring through endless schoolwork. I have an attachment to sports analogies so bear with ...

Approximately 10% of the world population is left-handed. What causes this anomaly?

While there are several theories that try to explain this trait -- such as the positioning of the baby during the final trimester, hormone exposure during pregnancy, or epigenetic factors -- the most consistent and hardwired explanation boils down to plain old genetics. In other words, the reason you're right-handed or left-handed is because it's written in your DNA.

Research suggests that handedness displays a complex inheritance pattern. For example, if both parents of a child are left-handed, there is a 26% chance of that child being left-handed. A large study of twins from 25,732 families also indicated that the heritability of handedness is roughly 24%.

A cognitive neuroscientist explains that the biological reason the image 'moves' is because the V5 (middle temporal visual area) part of your brain – devoted to motion processing – activates or fires due to the V4 part of your brain – devoted to colour and shape – becomes overstimulated.

In fact, V4 neurons are saturated so much that the resting firing frequency of middle temporal neurons is interpreted as an actual sensory signal. The effect of this illusion strictly depends on several factors, namely on the receptive field sizes (the illusion changes as a function of viewing distance), V4 preference for spirals and spheres, and the middle temporal involvement in 3D and stereopsis. It is a very complex interaction, that rarely lead to suc ...
