Phantom pain following spinal cord injury is the result of hypersensitive neurons in the thalamic region of brain

Yale researchers report the first evidence that phantom pain following spinal cord injury is the result of hypersensitive neurons in the thalamic region of the brain that can be suppressed with specially designed molecular agents.

Finding may significantly broaden understanding of how the brain selects and retains information

By examining how sounds are registered during the process of learning, UC Irvine neurobiologists have discovered a neural coding mechanism that the brain relies upon to register the intensity of memories based on the importance of the experience.

When it comes to pain - mind over matter works

According to experts in the U.S., they have strong scientific proof that mind over matter works for relieving pain.

Researchers discover discrete region of the monkey brain that processes pitch

Johns Hopkins researchers have discovered a discrete region of the monkey brain that processes pitch, the relative high and low points of sound, by recognizing a single musical note played by different instruments.

Asthmatics don't need to hear the word "wheeze"

According to a new study, as far as asthmatics are concerned, just the mention of words such as "wheeze" can activate an attack.

Study shows humans have ability to track odors

Though humans may never match the tracking ability of dogs, we apparently have the ability to sniff out and locate odors, according to a new study by scientists from the University of California, Berkeley.

Study reveals functional link between emotion processing centers in the brain and certain physiological processes relevant to disease

The mere mention of a stressful word like "wheeze" can activate two brain regions in asthmatics during an attack, and this brain activity may be associated with more severe asthma symptoms, according to a study by University of Wisconsin-Madison researchers and collaborators.

Inhibitory systems essential for controlling the pattern of activity in the cortex

Inhibitory systems are essential for controlling the pattern of activity in the cortex, which has important implications for the mechanisms of cortical operation, according to a Yale School of Medicine study in Neuron.

Mouse model of Rett Syndrome displays reduced cortical activity

Sacha Nelson of Brandeis University in Waltham, MA and Rudolf Jaenisch of the Whitehead Institute of Biomedical Research in Cambridge, MA and their colleagues report online in the Proceedings of the National Academy of Sciences Early Edition that spontaneous neuronal activity is reduced in the cortex of a knockout mouse model for the childhood neurodevelopmental disorder, Rett Syndrome.

First direct evidence that endorphins play a role in the phenomenon known as the placebo effect

Just thinking that a medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, and soothe painful sensations, a new University of Michigan study finds.

New drug CX717 can temporarily improve performance and reverse the effects of sleep deprivation

Research in monkeys suggests that a new drug can temporarily improve performance and reverse the effects of sleep deprivation on the brain, which would be a breakthrough in helping shift workers, health professionals, military personnel and others who must function at top performance in spite of sleep deficits.

New insight into the neural computational function represented by "error-related negativity"

Deciphering the subtle, complex electrical signals emanating from the brain has yielded important insights into the still-mysterious neural mechanisms that underlie behavior.

Endorphin system may hold the key to understanding and treating bulimia nervosa

The role of the brain's opioid receptor system - or endorphin system - may hold the key to understanding and treating bulimia nervosa, according to research reported in the Society of Nuclear Medicine's August issue of the Journal of Nuclear Medicine.

Researchers look at how we understand visual images

The figure is famous: a deceptively simple line drawing that at first glance resembles a vase and, at the next, a pair of human faces in profile. When you look at this figure, your brain must rapidly decide what the various lines denote. Are they the outlines of the vase or the borders of two faces? How does your brain decide?

Researchers pinpoint specific cause of defects in motor learning in Fragile X patients

While researchers have long known the genetic defect underlying Fragile X syndrome, they are still tracing how that defect creates the complex mix of mental retardation, hyperactive behavior, attention deficits, and other problems in the disorder.

Aging profile of the human brain differs greatly from that seen in chimpanzees

Researchers have found that the two primary areas of the human brain appear to age in radically different ways: The cortex used in higher-level thought undergoes more extensive changes with age than the cerebellum, which regulates basic processes such as heartbeat, breathing and balance.

Aging and gene expression in the primate brain

While medical science and a healthy lifestyle can help increase life expectancy, many aspects of aging and longevity are beyond our control. Published this week in the open-access journal PLoS Biology, Michael Eisen and colleagues shed light on these genetic factors by identifying sets of genes whose expression changes with age in human and chimp brains.

Brain may interpret the information it receives from sensory neurons using a code more complicated than scientists previously thought

...according to new research from the National Autonomous University of Mexico and Cold Spring Harbor Laboratory. By studying how monkeys perceive a vibrating object when it touches the skin, scientists found that changes in an animal's attention over time influence how a sensory signal is interpreted.

Effects of ostracism are a health concern

Ostracism is more powerful now than ever because people have fewer strong family and friend support systems to fall back on when faced with exclusion in relationships, the workplace or even Internet chat rooms, says a Purdue University social psychologist.

Cocaine induces abnormal enhancement of neuronal connections

Researchers working with rats have zeroed in on the brain circuitry mechanism whose disruption contributes to the impulsive behavior seen in users of cocaine as well as other psychostimulant drugs. The same circuitry has been implicated in such disorders as schizophrenia, depression, and post-traumatic stress disorder, wrote the researchers.
