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
2012-06-12 06:40:52

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...

Link Between Touch And Emotion Discovered
2012-06-05 04:36:07

Connie K. Ho for redOrbit.com Sight. Sound. Touch. These are just a few of the senses that the body has. This theme of senses was the subject of a recent study by neuroscientists from the California Institute of Technology (Caltech) who reported a relationship between touch and emotion via the brain´s primary somatosensory cortex. The findings, described in a recent issue of the Proceedings of the National Academy of Sciences (PNAS), were discovered by researchers Valeria Gazzola...

Researchers at the RUB and from Durham report Patients who are blind in one side of their visual field benefit from presentation of sounds on the affected side. After passively hearing sounds for an hour, their visual detection of light stimuli in the blind half of their visual field improved significantly. Neural pathways that simultaneously process information from different senses are responsible for this effect. "We have embarked on a whole new therapy approach" says PD Dr....

Research from Karolinska Institutet shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery, which is published in the scientific journal Neuron, is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals. "I've never...

Neurogenesis spurred by a high-fat diet encourages more eating and fat storage, animal study suggests New nerve cells formed in a select part of the brain could hold considerable sway over how much you eat and consequently weigh, new animal research by Johns Hopkins scientists suggests in a study published in the May issue of Nature Neuroscience. The idea that the brain is still forming new nerve cells, or neurons, into adulthood has become well-established over the past several...

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...

barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
