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...

Decision Making In The Brain

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...

Mildly stressful situations can affect our perceptions in the same way as life-threatening ones Financial loss can lead to irrational behavior. Now, research by Weizmann Institute scientists reveals that the effects of loss go even deeper: Loss can compromise our early perception and interfere with our grasp of the true situation. The findings, which recently appeared in the Journal of Neuroscience, may also have implications for our understanding of the neurological mechanisms underlying...

Double Positive Punch In Brain White Matter Prompted By Chinese Meditation
2012-06-12 06:46:04

Scientists studying the Chinese mindfulness meditation known as integrative body-mind training (IBMT) say they've confirmed and expanded their findings on changes in structural efficiency of white matter in the brain that can be related to positive behavioral changes in subjects practicing the technique regularly for a month. In a paper appearing this week in the online Early Edition of the Proceedings of the National Academy of Sciences, scientists Yi-Yuan Tang and Michael Posner report...

Area Of Brain Identified That Determines Distance From Which Sound Originates

MGH team uses functional imaging to find neurons sensitive to distance but not loudness Researchers at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital have identified a portion of the brain responsible for determining how far away a sound originates, a process that does not rely solely on how loud the sound is. The investigators' report, which will appear in the early edition of Proceeding of the National Academy of Sciences, is receiving early online release...

Stress may affect brain development in children – altering growth of a specific piece of the brain and abilities associated with it – according to researchers at the University of Wisconsin—Madison. "There has been a lot of work in animals linking both acute and chronic stress to changes in a part of the brain called the prefrontal cortex, which is involved in complex cognitive abilities like holding on to important information for quick recall and use," says Jamie...

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...
