Imaging Neural Pathways In Brain Show Intelligence Levels
2012-08-02 12:51:02

Connie K. Ho for redOrbit.com — Your Universe Online The brain is an intricate part of the body to say the least. And new research has focused on the effect of neural connectivity on one area of these intricacies, imaging a person's brain to estimate their level of intelligence. Researchers have long thought that overall brain size can affect individual variations in intelligence. A past study delved into this particular topic and demonstrated that the brain´s lateral...

The More Altruistic You Are, The More Gray Matter You Have
2012-07-11 20:45:39

The volume of a small brain region influences one's predisposition for altruistic behavior. Researchers from the University of Zurich show that people who behave more altruistically than others have more gray matter at the junction between the parietal and temporal lobe, thus showing for the first time that there is a connection between brain anatomy, brain activity and altruistic behavior. Why are some people very selfish and others very altruistic? Previous studies indicated that social...

Researchers decode a molecular mechanism that sheds light on how trauma can become engraved in the brain Feelings of anxiety very effectively prevent people from getting into situations that are too dangerous. Those who have had a terrible experience initially tend to avoid the place of tragedy out of fear. If no other oppressive situation arises, normally the symptoms of fear gradually subside. "The memory of the terrible events is not just erased." states first author, PD Dr. Andras...

Success in applying the technique to the basal ganglia, a brain region that is involved in movement disorders such as Parkinson's disease In the brains of humans and non-human primates, over 100 billion nerve cells build up complicated neural circuits and produce higher brain functions. When an attempt is made to perform gene therapy for neurological diseases like Parkinson's disease, it is necessary to specify a responsible neural circuit out of many complicated circuits. Until now,...

Neurons come in an astounding assortment of shapes and sizes, forming a thick inter-connected jungle of cells. Now, UCL neuroscientists have found that there is a simple pattern that describes the tree-like shape of all neurons. Neurons look remarkably like trees, and connect to other cells with many branches that effectively act like wires in an electrical circuit, carrying impulses that represent sensation, emotion, thought and action. Over 100 years ago, Santiago Ramon y Cajal, the...

Researchers at the RIKEN Brain Science Institute (BSI) in Japan have uncovered two brain signals in the human prefrontal cortex involved in how humans predict the decisions of other people. Their results suggest that the two signals, each located in distinct prefrontal circuits, strike a balance between expected and observed rewards and choices, enabling humans to predict the actions of people with different values than their own. Every day, humans are faced with situations in which they...

Concordia research helps develop first brain map of love and desire Thanks to modern science, we know that love lives in the brain, not in the heart. But where in the brain is it — and is it in the same place as sexual desire? A recent international study is the first to draw an exact map of these intimately linked feelings. "No one has ever put these two together to see the patterns of activation," says Jim Pfaus, professor of psychology at Concordia University. "We didn't know...

Front-most part of the cortex involved in making short-term predictions about what will happen next Researchers at the University of Iowa, together with colleagues from the California Institute of Technology and New York University, have discovered how a part of the brain helps predict future events from past experiences. The work sheds light on the function of the front-most part of the frontal lobe, known as the frontopolar cortex, an area of the cortex uniquely well developed in humans...

Patience And Self Control Illustrated In Brain Imaging
2012-06-19 09:04:54

Connie K. Ho for redOrbit.com Not taking a piece of chocolate cake is easy during the first ten minutes. However, trying to not take a piece of that same cake after 30 minutes is even more difficult. The reasoning behind this challenge is described in a new research project focused on patience and self-control. Scientists from the University of Iowa (UI) recently revealed that they discovered what the brain looks like when a person loses patience and self control with fMRI images. In...

Newly clarified function of 'indirect pathways' from brain to spinal motor neurons, controlling dexterous hand movements by newly developed 'the double viral vector transfection technique' The collaborative research team led by Professor Tadashi ISA, Project Assistant Professor Masaharu KINOSHITA from The National Institute for Physiological Sciences, The National Institutes of Natural Sciences and Fukushima Medical University and Kyoto University, developed "the double viral vector...

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...

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...

cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
