Evolution Is A Matter Of Brawn Vs Brain
2012-10-16 06:07:56

April Flowers for redOrbit.com - Your Universe Online Brain size relevant to body size has been the most common measurement of intelligence in animals, but it may not be as dependent on evolutionary selection of the brain as was previously thought. This is according to a new study published this week in the Proceedings of the National Academy of Sciences. A generation of scientists has used brain size relative to body size to predict an animal's intelligence. An example is the human...

An Evolutionary Biologist at The University of Manchester, working with scientists in the United States, has found compelling evidence that parts of the brain can evolve independently from each other. It's hoped the findings will significantly advance our understanding of the brain. The unique 15 year study with researchers at the University of Tennessee and Harvard Medical School also identified several genetic loci that control the size of different brain parts. The aim of the...

Human Brain Growth Outpaces Chimps In Womb
2012-09-25 13:07:57

Watch the Video April Flowers for redOrbit.com - Your Universe Onlin A new study from Kyoto University shows that human's superior brain size in comparison to chimpanzees can be traced back to the womb. Appearing in the September 25 issue of Current Biology, the study is the first to track and compare brain growth in chimp and human fetuses. "Nobody knew how early these differences between human and chimp brains emerged," said Satoshi Hirata of Kyoto University. Hirata's research...

New Human Brain Atlas Based on Gene Expression
2012-09-20 09:33:54

April Flowers for  redOrbit.com - Your Universe Online A research team from the Allen Institute for Brain Science reports that human brains share a consistent genetic blueprint and possess enormous biochemical complexity. The findings, published in Nature, stem from the first in-depth and large-scale analysis of the vast data set publicly available in the Allen Human Brain Atlas. The Allen Human Brain Atlas fully integrates different kinds of data across different scales of brain...

Emotiv - Hacking The Human Brain
2012-08-27 09:45:58

Michael Harper for redOrbit.com — Your Universe Online Our minds are often the most secure place we can go to think thoughts otherwise unspeakable to human ears. We may not agree with every thought we have and might even be ashamed by many of them, yet there they are, striking the core of our minds like lightning; quick and unpredictable. As such, it could be quite embarrassing and frightening to know someone not only has access to our brains, but knows what we´re thinking....

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...

Different Areas Of The Brain Are Used For Thinking And Choosing
2012-08-21 14:31:55

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)...

Study Reveals Brain's Mysterious Switchboard Operator
2012-08-17 16:08:49

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found. The researchers report in the journal Science that an area of our brain called the pulvinar regulates communication between clusters of brain cells as our brain focuses on the people and objects that need our attention. Like a switchboard operator, the...

Cleansing System Inside Brain Drains Waste Products
2012-08-16 12:47:44

Connie K. Ho for redOrbit.com — Your Universe Online Researchers recently discovered a cleansing system in the brain with a new imaging technique. Neuroscientists at the University of Rochester Medical Center found a system that can drain the waste from the brain; it was previously unrecognized by scientists. The system is highly organized and is designed with a series of pipes that depend on the brain´s blood vessels, providing the same function in the brain as the...

UT Dallas researchers recently demonstrated how nerve stimulation paired with specific experiences, such as movements or sounds, can reorganize the brain. This technology could lead to new treatments for stroke, tinnitus, autism and other disorders. In a related paper, UT Dallas neuroscientists showed that they could alter the speed at which the brain works in laboratory animals by pairing stimulation of the vagus nerve with fast or slow sounds. A team led by Dr. Robert Rennaker and...
