April Flowers for redOrbit.com - Your Universe Online A noise in the dark, a rustle in the undergrowth; these are sounds likely to make an animal or a person stop sharply and be still, anticipating a predator. Freezing is part of the natural fear response, a reaction to a stimulus in the environment and part of how the brain decides whether to be afraid of it. A new study released by a neuroscience group at Cold Spring Harbor Laboratory (CSHL) examines how fear responses are learned,...
Brett Smith for redOrbit.com – Your Universe Online The majority of the scientific community has embraced the idea of different smells being based on the olfactory receptors’ ability to detect various shapes of odor molecules. However, a new study in the open access journal PLOS ONE has given credence to a less popular theory; that the sense of smell is based on the molecules’ different vibrations, not their shapes. The idea of a quantum, or vibration, basis for olfactory was...
Brains of older people may well have abilities that younger folks have not yet developed. Rose Cottage Press details new study linking weight training to better memory, decision making, and problem solving. Whitefield, New Hampshire (PRWEB) January 23, 2013 Now for some really good news about brain health. Scientists (and thus the rest of us,) used to think that after reaching age thirty the picture was grim, beginning with lost keys, loss of comprehension, followed by confusion,...
Tufts neuroscientists find that starry brain cells can be used to mimic sleep deprivation Neuroscience researchers from Tufts University have found that our star-shaped brain cells, called astrocytes, may be responsible for the rapid improvement in mood in depressed patients after acute sleep deprivation. This in vivo study, published in the current issue of Translational Psychiatry, identified how astrocytes regulate a neurotransmitter involved in sleep. The researchers report that the...
redOrbit Staff & Wire Reports - Your Universe Online A pair of Harvard University stem cell biologists have reportedly demonstrated a technique with which they can transform one type of already differentiated neuron into another. The discovery, reported by the Cambridge, Massachusetts-based Ivy League school in a statement released Sunday, demonstrates it is possible that the human brain “is not as immutable as we always thought, because at least during an early window of time one...

An experimental oral drug given to mice after a spinal cord injury was effective at improving limb movement after the injury, a new study shows. The compound efficiently crossed the blood-brain barrier, did not increase pain and showed no toxic effects to the animals. "This is a first to have a drug that can be taken orally to produce functional improvement with no toxicity in a rodent model," said Sung Ok Yoon, associate professor of molecular & cellular biochemistry at Ohio State...
Insect research yields insights for muscle control and nerve disorders in mammals, including humans Working with fruit flies, Johns Hopkins scientists have decoded the activity of protein signals that let certain nerve cells know when and where to branch so that they reach and connect to their correct muscle targets. The proteins’ mammalian counterparts are known to have signaling roles in immunity, nervous system and heart development, and tumor progression, suggesting broad...

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...
