In a breakthrough for understanding brain evolution, neuroscientists have shown that differences between primate brains - from the tiny marmoset to human – can be largely explained as consequences of the same genetic program. In research published in the Journal of Neuroscience, Professor Marcello Rosa and his team at Monash University's School of Biomedical Sciences and colleagues at Universidade Federal do Rio de Janeiro, in Brazil, used computer modelling to demonstrate that the...

Socialness In Carnivores Linked To Size Of Frontal Cortex
2013-10-09 05:49:36

April Flowers for redOrbit.com - Your Universe Online A growing body of research from Michigan State University reveals that the region of the brain that makes humans and primates social creatures may play a similar role in carnivores. Sharleen Sakai, professor of neuroscience, has studied spotted hyenas, lions, and most recently the raccoon family to find a correlation between the size of the animals' frontal cortex and their social nature. The current study, published in the journal...

Chronic Dizziness May Be Helped By Magnetic Stimulation
2013-10-09 04:55:36

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Johns Hopkins University School of Medicine believe that they have located a specific site in the human brain that could be one of the sources of dizziness and spatial disorientation. While dizziness can also be linked to damage to the inner ear, or to other senses such as vision, neurology instructor Dr. Amir Kheradmand and his colleagues report that they have discovered a region of the brain that plays a...

Inhibitory neuron type found to specifically suppress activation of other inhibitory neurons in cerebral cortex The cerebral cortex contains two major types of neurons: principal neurons that are excitatory and interneurons that are inhibitory, all interconnected within the same network. New research now reveals that one class of inhibitory neurons – called VIP interneurons -- specializes in inhibiting other inhibitory neurons in multiple regions of cortex, and does so under specific...

Spinning Doesn't Dizzy Ballerinas Due To Brain Conditioning
2013-09-27 13:46:12

Brett Smith for redOrbit.com - Your Universe Online Spinning around in circles causes dizziness in most people, which could be a problem for figure skaters or ballerinas who must perform several spins during a typical routine. However, new research in the journal Cerebral Cortex indicates that ballerinas may have conditioned their brain to better handle a series of quick spins. Study researchers said their findings could be used to improve treatments for patients with chronic dizziness....

Bird Brain Map Gets Major Revisions

Brett Smith for redOrbit.com - Your Universe Online Using state-of-the-art genetic and diagnostic tools, researchers from Duke University and the University of California, San Diego have re-contextualized the map of the avian brain, as described to two separate papers published in the Journal of Comparative Neurology. The researchers noted many similarities between the avian brain and mammalian brain – leading them to conclude that all vertebrates have more in common with respect to...

Space Around Other People Perceived Just As Our Own
2013-09-05 16:14:56

Karolinska Institutet A study from Karolinska Institutet in Sweden has shown that neurons in our brain 'mirror' the space near others, just as if this was the space near ourselves. The study, published in the scientific journal Current Biology, sheds new light on a question that has long preoccupied psychologists and neuroscientists regarding the way in which the brain represents other people and the events that happens to those people. "We usually experience others as clearly separated...

Brain Controls Volume Of Voices In Your Head
2013-09-04 10:24:06

Brett Smith for redOrbit.com - Your Universe Online During a conversation, the brain constantly makes adjustments in order to efficiently process the speech volume of others while recognizing self-made speech for what it is. According to a new report published this week in The Journal of Neuroscience, Duke researchers have mapped the complex brain interactions responsible for the ability to hold a conversation or play a musical instrument. What's more, the team believes that their...

Scientists Grow Mini Brain In Lab
2013-08-29 10:58:22

Michael Harper for redOrbit.com - Your Universe Online In the ongoing quest to better understand the human brain, scientists from the Austrian Academy of Sciences have been growing their own mini brains. These small collections of tissue aren’t capable of thought and are much smaller than a fully developed brain, but scientists say they’re still very valuable research tools. The brain matter began life as stem cells suspended in gel, which were then submerged into a solution of...

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...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
