There are many people who dislike clashing dissonances of some modernist composers. It’s been long thought that dissonant musical chords contain acoustic frequencies that interfere with another, disturbing people. Now, a new study indicates that humans prefer consonant chords because of the mathematical relationship between the many different frequencies that make up the sounds.

General Anesthetic Induces Slow Oscillations, Disrupts Brain Communication

patient-general-anesthesia

Little is known about general anesthetics, the drugs that put patients in a coma-like state, feeling no pain or discomfort while being operated on. A new study shows that these classes of drugs change the activity of a specific region of the brain and make it more difficult for the parts to communicate.

The addition of a light-sensitive protein to a small part of a rat’s brain allowed researchers to silence the neurons in the infralimbic cortex (ILC) with a flash of yellow light, delivered to the rat’s brain via an optic fiber. The light flashes for three seconds and the habit disappears.

New Analysis Focuses on “Pre-Feelings” & Ability to Anticipate Near Future

human-presentiment

A new study reports that presentiment without any external clues may exist. Researchers from Northwestern University analyzed the results of 26 studies published between 1978 and 2010 to figure out if the human body could prepare itself for future events.

Structures in the brains of great sharks are similar to the ones found in humans, and these could be the key to prevent further shark attacks. Animal biologists at the University of Western Australia have discovered that the brains of Carcharodon carcharias have similarities in terms of the regions that are dedicated to visual input to those found in human brains.
