    Calculating Whiskers Send Precise Information to the Brain

    After studying whiskers in rats for over a decade, Prof. Ehud Ahissar tried connecting the animals to a computer to better see how the whiskers – which have sensory organs – work. He and his team found that whiskers do more than send signals: they connect the animal and its environment, and give the brain all the information it needs to understand the signals.

  • Behind Closed Eyes

    Even when our eyes are closed, the visual centers in our brain are humming with activity. Now, new Weizmann Institute research has revealed details about the nature of brain activity during rest.

  • Science Tips, April 2011

    Three research updates from the Weizmann Institute of Science: why the ""aha!"" moment is important; an enzyme that can enhance memories; and how quantum mechanics principles of spin relate to biology.

    Past Brain Activation Revealed in Scans

    By studying brain wave patterns, Weizmann scientists found that such patterns preserve traces of previous cognitive activity. Like archaeologists, they may be able to uncover our history of past experiences, possibly revealing what makes us unique. It could also potentially enable diagnosis of neuropsychological diseases.

  • The Smell of White

    White light and white noise are made up of a range of sound or light waves mixed together. Now, in research that challenges basic assumptions about the sense of smell, Weizmann scientists have found that there are also ""white smells""– odors that seem basically the same, despite being blended from different molecules.

    A Lesson in Sleep Learning

    Using tones and odors, Prof. Noam Sobel and his team of neurobiologists have found that people can learn new information while asleep, and that what they learn can modify their waking behavior.
