Chocolate Cravings Connected To Brain
2012-09-21 08:50:55

Connie K. Ho for redOrbit.com — Your Universe Online A new study has revealed that the brain might have chocolate temptations due to the production of a natural chemical that is similar to opium. The researchers looked at a group of rats to better understand the urge to overeat chocolate candies. They injected a drug that sent an artificial boost to the neostriatum, a region in the brain. With the injection, the rats ate more than double the number of M&M chocolates than they...

Scientists have discovered the first direct evidence that a biological mechanism long suspected in epilepsy is capable of triggering the brain seizures — opening the door for studies to seek improved treatments or even preventative therapies. Researchers at Cincinnati Children's Hospital Medical Center report Sept. 19 in Neuron that molecular disruptions in small neurons called granule cells — located in the dentate gyrus region of the brain — caused brain seizures in...

Research in October issue of Nature Neuroscience sheds new light on the mechanics of memory Ben W. Strowbridge, PhD, Professor of Neurosciences and Physiology/Biophysics, and Robert A. Hyde, a fourth year MD/PhD student in the neurosciences graduate program at Case Western Reserve University School of Medicine, have discovered how to store diverse forms of artificial short-term memories in isolated brain tissue. "This is the first time anyone has found a way to store information over...

Lee Rannals for redOrbit.com — Your Universe Online Scientists have finally confirmed what most have already known for generations and generations, men and women see things differently. Scientists reported in the journal Biology of Sex Differences that men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors. Researchers from Brooklyn and Hunter Colleges of the City University of New York compared the vision...

Self-awareness In Humans Is More Intricate Than Previously Thought
2012-08-23 07:18:36

Ancient Greek philosophers considered the ability to "know thyself" as the pinnacle of humanity. Now, thousands of years later, neuroscientists are trying to decipher precisely how the human brain constructs our sense of self. Self-awareness is defined as being aware of oneself, including one's traits, feelings, and behaviors. Neuroscientists have believed that three brain regions are critical for self-awareness: the insular cortex, the anterior cingulate cortex, and the medial prefrontal...

Code In Brain Key To Pronouncing Vowels, Could Help Speech Paralysis
2012-08-22 14:23:42

Connie K. Ho for redOrbit.com — Your Universe Online Loss of muscle functioning in the body. Difficulty transferring message from the brain to muscles. These are just a few traits of paralysis that scientists examined in terms of its relationship to speech. A recent study by University of California, Los Angeles (UCLA) and Technion, Israel's Institute of Technology, researchers revealed a code in the brain that helps pronounce vowels. According to the researchers, human speech...

Different Areas Of The Brain Are Used For Thinking And Choosing

Caltech researchers study over 300 lesion patients The frontal lobes are the largest part of the human brain, and thought to be the part that expanded most during human evolution. Damage to the frontal lobes–which are located just behind and above the eyes–can result in profound impairments in higher-level reasoning and decision making. To find out more about what different parts of the frontal lobes do, neuroscientists at the California Institute of Technology (Caltech)...

Research results reported in Restorative Neurology and Neuroscience Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves. Their results are...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
