In life, many tasks have a context that dictates the right actions, so when people learn to do something new, they'll often infer cues of context and rules. In a new study, Brown University brain scientists took advantage of that tendency to track the emergence of such rule structures in the frontal cortex — even when such structure was not necessary or even helpful to learn — and to predict from EEG readings how people would apply them to learn new tasks speedily. Context and rule...

Hippocampus Stores Memories By Temporal Context
2014-03-14 09:49:22

[ Watch the Video: Recollection of Times Past: How the Brain Stores Memories ] UC Davis Before I left the house this morning, I let the cat out and started the dishwasher. Or was that yesterday? Very often, our memories must distinguish not just what happened and where, but when an event occurred — and what came before and after. New research from the University of California, Davis, Center for Neuroscience shows that a part of the brain called the hippocampus stores memories by their...

Colors And Shapes Can Be Heard By The Blind: Study
2014-03-11 06:52:16

[ Watch the Video: EyeMusic Live Demo at AIPAC ] April Flowers for redOrbit.com - Your Universe Online Normally, people perceive colors and shapes visually, but what if you could "hear" them? A new study from Hebrew University shows that using sensory substitution devices (SSDs), colors and shapes can now be conveyed to the brain noninvasively through other senses. Prof. Amir Amedi, of the Edmond and Lily Safra Center for Brain Sciences and the Institute for Medical Research...

Brett Smith for redOrbit.com - Your Universe Online A new study on the brains of mustached bats could provide a window into our own cognitive processes, according to a report published in the journal Frontiers in Physiology on Tuesday. In the study, a pair of Georgetown University researchers found that a small region within the bats’ brains called the amygdala, a structure in the brains of all mammals, controls the production of emotionally-specific calls and sounds. The team said...

Brain Activity During Slow-Wave-Sleep Differs Between Mammals And Birds
2014-03-05 10:40:23

Max Planck Institute When we drift into deep slow-wave sleep (SWS), waves of neuronal activity wash across our neocortex. Birds also engage in SWS, but they lack this particular brain structure. Researchers from the Max Planck Institute for Ornithology in Seewiesen, Germany together with colleagues from the Netherlands and Australia have gained deeper insight into the sleeping avian brain. They found complex 3D plumes of brain activity propagating through the brain that clearly differed...

Keep this in mind: Scientists say they've learned how your brain plucks information out of working memory when you decide to act. Say you're a busy mom trying to wrap up a work call now that you've arrived home. While you converse on your Bluetooth headset, one kid begs for an unspecified snack, another asks where his homework project has gone, and just then an urgent e-mail from your boss buzzes the phone in your purse. During the call's last few minutes these urgent requests — snack,...

Deep Brain Region Controls How Quickly We Make Decisions About Love
2014-02-14 12:47:19

Lee Rannals for redOrbit.com - Your Universe Online According to a study published in the journal Current Trends in Neurology, a region found deep within the brain is able to control how quickly people make decisions about love. The research is the first to provide causal clinical evidence that an area of the brain known as the anterior insula plays an instrumental role in love. “The current work makes it possible to disentangle love from other biological drives,” the authors...

MRI Study Shows How The Brain Finds Beauty In Mathematics
2014-02-13 12:39:43

Peter Suciu for redOrbit.com - Your Universe Online To many people math is work, often times hard work. Yet for those who appreciate the beauty of mathematics it can activate the same part of the brain that can appreciate great art or music. To those math lovers an aesthetically pleasing formula is art, and this now suggests that there could be a neurobiological basis to beauty. Thus beauty is truly in the eyes of the beholder, and researchers from University College London, Imperial...

Males Differ From Females In Specific Brain Structures
2014-02-12 13:09:03

University of Cambridge Reviewing over 20 years of neuroscience research into sex differences in brain structure, a Cambridge University team has conducted the first meta-analysis of the evidence, published this week in the prestigious journal Neuroscience and Biobehavioral Reviews. The team, led by doctoral candidate Amber Ruigrok and Professors John Suckling and Simon Baron-Cohen in the Department of Psychiatry, performed a quantitative review of the brain imaging literature testing...

Genetic Variation Linked To Intellectual Ability
2014-02-12 04:19:25

Brett Smith for redOrbit.com - Your Universe Online Previous research studies have demonstrated that the thickness of the cerebral cortex, or “cortical thickness,” is closely related to intellectual ability, and a new study from scientists at King's College London has revealed a gene related to both cortical thickness and intelligence . Published in the journal Molecular Psychiatry, the new study could help reveal the biological mechanisms behind some forms of intellectual...

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...
