Can You Find The "T" In This Image?

Mastering the art of ignoring is very useful, especially when it comes to visually searching for things, according to a new study from Johns Hopkins University.
It's obvious that clues and information on what you're searching for can make the task of finding something a lot easier. However, a team of psychologists wanted to prove that hints on what not to look for can be just as helpful in visually taxing tasks.

Scientists have found a method to decode what a person is perceiving

Neuroscientists have developed a new technique that enables them to decode what people are perceiving just by looking at a readout of their brain signals. This ability to spontaneously decipher human consciousness in real-time could have wide-ranging implications, potentially leading to novel treatments for brain injuries or helping people with locked-in syndrome to communicate.
The researchers collaborated with seven epilepsy patients at a hospital in Seattle, who had a number of electrodes called electrocorticographic (ECoG) arrays implanted into their brains. These targeted the temporal and occipital lobes of the brain's cortex, concerned with hearing and vision, respectively.
Patients were each shown a series of grayscale images of faces and houses, which flashed up on a screen in a random order for 400 milliseconds each. Using a novel framework for interpreting subjects’ brain activity data, the researchers were able to tell exactly when each patient had seen an image, and what that image contained. A report of this process has been published in the journal PLOS Computational Biology.
Lead researcher Kai Miller told IFLScience that “there have been other studies where scientists have been able to tell when a patient is looking at one type of an image or another, but the timing of this stimulus had always been known ahead of time.
“However, we were able to decode spontaneously from the signal, so we were able to look at the brain signal and say at this point in time they saw this particular type of image.” To achieve this, the team focused on two types of brain signals: event-related potentials (ERPs) and broadband.

Electrodes were implanted into the temporal and occipital lobes of epilepsy patients, and used to measure their brain activity when viewing a series of images. Kai Miller, Stanford University

Scientists shed new light on how the brain detects motion



Scientists have discovered that the neural pathways involved in detecting motion differ depending on whether the moving object is alive or not

If you’ve managed to avoid getting hit by a bus today, you should thank your brain, which is designed to detect motion in order to help us safely navigate the world around us. This ability is so vital for our survival as a species that we’ve even developed the capacity to detect “implied motion,” such as movement that is suggested in still photographs. Yet while most of us take this for granted, scientists have long struggled to understand the neural pathways that control this essential function.
Publishing their findings in the journal NeuroImage, a team of researchers from Dartmouth College have now shed new light on how the brain interprets motion, indicating that the two pathways involved in this process may be more integrated than previously thought. Additionally, their results suggest that motion is processed differently depending on whether the moving object is animate or inanimate.

The impact of smartphone thumbing on your brain

Almost like a new drug, our addiction to using our smartphones is having a profound effect on our brains. Whether we’re texting, posting on Facebook, or playing Angry Birds, the way we’re repetitively using our fingers and thumbs on the smooth surface of a touch screen is causing certain areas of our brains to become bigger. In other words, we’re experiencing heightened brain activity that rewires sensory processing when our fingertips and thumbs are touched, a phenomenon known as “brain plasticity” in which the brain adapts to learning new things.
