Magnetic Stimulation Effective in Helping Parkinson's Patients Walk

Aug. 31, 2015 — About 50 percent of patients with Parkinson's disease (PD) experience freezing of gait (FOG), an inability to move forward while walking. This can affect not only mobility but also balance. In a ... read more

Aug. 31, 2015 — For more than a hundred years, people have known that dendritic arbors -- the projections that neurons use to receive information from other neurons -- differ in size and shape depending on neuron ... read more

Testosterone Changes Brain Structures in Female-to-Male Transsexuals

Aug. 31, 2015 — Brain imaging shows that testosterone therapy given as part of sex reassignment changes the brain structures and the pathway associated with speech and verbal fluency. This result supports research ... read more

Food May Be Addictive: Food Craving May Be 'Hard-Wired' in the Brain

Aug. 31, 2015 — An international group of researchers have found that food craving activates different brain networks between obese and normal weight patients. This indicates that the tendency to want food may be ... read more

Psychotic Patients Distinguished from Controls While Watching Movie Alice in Wonderland

Aug. 31, 2015 — Researchers using fMRI (functional Magnetic Resonance Imaging) have found that even first-episode psychotic patients process information differently from a control group. To ensure both groups ... read more

A Single Cocaine Dose Lowers Perceptions of Sadness and Anger

Aug. 30, 2015 — A single dose of cocaine can interfere with the ability to recognize negative emotions such as anger and sadness, according to new ... read more

Scientists Show How Magnetic Pulses Change the Brain in Treatment for Depressed Patients

Aug. 30, 2015 — A group of scientists have found a way of understanding how transcranial magnetic stimulation (TMS) can give relief to severely depressed patients. TMS is used as an alternative to electro-convulsive ... read more

Borderline Personality Traits Linked to Lowered Empathy

Aug. 29, 2015 — Those with borderline personality disorder, or BPD, a mental illness marked by unstable moods, often experience trouble maintaining interpersonal relationships. New research indicates that this may ... read more

Neurobiology: Light-Activated Learning

Aug. 28, 2015 — Scientists have developed a light-sensitive switch that regulates a protein implicated in the neurobiology of synaptic plasticity. The agent promises to shed new light on the phenomenology of ... read more

Aug. 28, 2015 — A new device which transforms paralysis victims’ breath into words – believed to be the first invention of its kind – has been ... read more

Brain Scans Predict Response to Antipsychotic Medications

Aug. 28, 2015 — Investigators have discovered that brain scans can be used to predict patients' response to antipsychotic drug ... read more

Air Pollution Linked to Children's Low Academic Achievement

Aug. 27, 2015 — A new study on children's health has found that fourth and fifth graders who are exposed to toxic air pollutants at home are more likely to have lower ... read more

Degenerating Neurons Respond to Gene Therapy Treatment for Alzheimer's Disease

Aug. 27, 2015 — Degenerating neurons in patients with Alzheimer's disease measurably responded to an experimental gene therapy in which nerve growth factor was injected into their brains, report ... read more

Aug. 27, 2015 — Scientists have discovered that in addition to proteins, lipids are also necessary for guiding axons. The study shows how a phospholipid released by glial cells -- the cells in the nervous system ... read more

Aug. 27, 2015 — Research may lead to reevaluation of the current understanding of information flow and neural circuit maturation in the visual ... read more

Aug. 27, 2015 — Neuroscientists have discovered a set of cholinergic neurons in the basal forebrain that broadcast messages throughout the cerebral cortex, rapidly informing multiple distributed subregions of any ... read more

Creative and Neurotic: Is Neuroticism Fueled by Overthinking?

Aug. 27, 2015 — Psychologists have presented a new theory for why neurotic unhappiness and creativity go hand-in-hand. The authors argue that the part of the brain responsible for self-generated thought is highly ... read more

Parkinson’s Disease Brain Cells at Risk of Burnout, Like an Overheating Motor

Aug. 27, 2015 — The death of brain cells in Parkinson’s disease may be caused by a form of cellular energy crisis in neurons that require unusually high quantities of energy to carry out their job of regulating ... read more

Alzheimer’s Disease Thought to Be Accelerated by an Abnormal Build-Up of Fat in the Brain

Aug. 27, 2015 — People with Alzheimer’s disease have fat deposits in the brain. For the first time since the disease was described 109 years ago, researchers have discovered accumulations of fat droplets in the ... read more

Aug. 27, 2015 — Researchers have tested a new device for delivering hormone treatments for mental illness through the nose. This method was found to deliver medicine to the brain with few side ... read more
