Aging…
Zachariah Reagh, assistant professor of psychological and brain sciences in Arts & Sciences at Washington University in St. Louis found that brain activity in older adults isn’t necessarily quieter when it comes to memory. “It’s just different,” he said. What he found out is that while a 20-year-old notes all details in a movie, an…

Ignore… you!
Electric fish generate electric pulses to communicate with other fish and sense their surroundings. Some species broadcast shorter electric pulses, while others send out long ones. But all that zip-zapping in the water can get confusing. The fish need to filter out their own pulses so they can identify external messages and only respond to…

A new study offers evidence that the brain’s inferotemporal cortex, which is specialized to perform object recognition, has been repurposed for a key component of reading called orthographic processing – the ability to recognize written letters and words. (1) As we change, our brain changes. As our brain changes, we change. A constant battle leading…

The brain never processes the same information in the same way. Scientists have found out why this is the case and how it works. A decisive role plays a critical state of the neuronal networks. It seems that there is always a certain amount of activity between the neurons of a network, even if there…

Brain. Skin. Thinking. Not being.
Brain activity has an unmistakable signature: the firing of neurons, as brain cells relay information to one another through the triggered release of chemical neurotransmitters, which are received by the long, branching dendrites of neighbouring cells. This microscopic ritual is distinctive, but it doesn’t belong only to neurons. Scientists have now found bursts of neuron-like…
