Scientists Probe Source Of A Pulsing Signal In The Sleeping Brain
2013-04-18 13:35:40

Technische Universitaet Muenchen New findings clarify where and how the brain's "slow waves" originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory. For the first time, researchers have shown conclusively that slow waves start in the cerebral cortex, the part of the brain responsible for cognitive functions. They also found that such a wave...

Scientists at the Stanford University School of Medicine have determined the precise anatomical coordinates of a brain "hot spot," measuring only about one-fifth of an inch across, that is preferentially activated when people view the ordinary numerals we learn early on in elementary school, like "6" or "38." Activity in this spot relative to neighboring sites drops off substantially when people are presented with numbers that are spelled out ("one" instead of "1"), homophones ("won"...

A Little Brain Stimulation Helps Curb Smoking Triggers
2013-04-16 21:48:04

Lee Rannals for redOrbit.com — Your Universe Online Feeling like you need to burn one down after a traffic jam or your boss chewing you out? Well, a new study suggests a little brain stimulation may help you stay away from those cancer sticks. The research shows a single, 15-minute session of high frequency transcranial magnetic stimulation (TMS) over the prefrontal cortex temporarily reduces those trigger cravings. Nicotine activates the dopamine system and reward-related...

Music Activates Same Pleasure Center In The Brain As Sex
2013-04-14 07:40:13

redOrbit Staff & Wire Reports — Your Universe Online Listening to good music can trigger the same reaction in our brains as eating a good meal, taking a psychoactive drug or enjoying an evening of passion, researchers from McGill University in Montreal claim in a new study. The research, which was published in the journal Science, reported the nucleus accumbens is the part of the brain that is most closely associated with the enjoyment a person experiences when listening to a...

Lasers May Help Cure Cocaine Addiction
2013-04-05 09:03:05

redOrbit Staff & Wire Reports - Your Universe Online New hope for the estimated 1.4 million Americans addicted to cocaine could come in the form of a laser-inspired treatment that could effectively turn off their craving for the illicit drug, claims research published in this week´s edition of the journal Nature. According to HealthDay News, scientists from the University of California, San Francisco (UCSF) and the US National Institute of Drug Abuse (NIDA) used laser light to...

Brain's Visual Cortex Activates For Reward Even When Stimulus Is Removed
2013-03-22 12:15:13

Alan McStravick for redOrbit.com - Your Universe Online An international collaborative study, conducted by researchers at both KU Leuven and the Harvard Medical School, has attempted to recreate Ivan Pavlov´s famous experiment, but with a twist. Pavlov, you may know, was famous for conducting a study where a stimulus was introduced and the reward for that stimulus was slowly removed, with the aim of observing whether or not a physiological response would continue to be registered...

Midbrain
2013-07-25 15:13:23

The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...

Brain
2013-03-05 13:54:00

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
