Patients with Parkinson disease-related dementia appear to have increased brain atrophy in the hippocampal, temporal and parietal lobes and decreased prefrontal cortex volume compared to patients with Parkinson disease without dementia, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archivesjournals. The study was conducted by Daniel Weintraub, M.D., […]

Recent PET-measurements in Turku, Finland, show that the GSM mobile phone electromagnetic field suppresses glucose metabolism in temporoparietal and anterior temporal areas of the hemisphere next to the antenna. Thirteen young healthy males were exposed to the GSM signal for 33 minutes.
Although out-of-body experiences (OBEs) are typically associated with migraine, epilepsy, and psychopathology, they are quite common in healthy and psychologically normal individuals as well. However, they are poorly understood. A new study, published in the July 2011 issue of Elsevier’s Cortex, has linked these experiences to neural instabilities in the brain’s temporal lobes and to […]
Young babies’ brains are already specially attuned to the sounds of human voices and emotions, according to a report published online on June 30 in Current Biology, a Cell Press publication. Three- to seven-month-old infants showed more activation in a part of the brain when they heard emotionally neutral human sounds, such as coughing, sneezing, […]
Functional magnetic resonance imaging (fMRI) may provide an early and objective indicator of autism, according to researchers at Columbia University in New York City, who used the technique to document language impairment in autistic children. Results of their study appear online and in the August issue of Radiology.
In one of the first studies of its kind, UCLA researchers used a unique brain scan to assess the levels of amyloid plaques and neurofibrillary tangles — the hallmarks of Alzheimer’s disease — in adults with Down syndrome. Published in the June edition of the Archives of Neurology, the finding may offer an additional clinical tool […]
Each time you see a person that you know, your brain rapidly and seemingly effortlessly recognizes that person by his or her face. Until now, scientists believed that only a couple of brain areas mediate facial recognition. However, Carnegie Mellon University’s Marlene Behrmann, David Plaut, and Adrian Nestor have discovered that an entire network of […]
For decades, autism researchers have faced a baffling riddle: how to unravel a disorder that leaves no known physical trace as it develops in the brain. Now a UCLA study is the first to reveal how the disorder makes its mark at the molecular level, resulting in an autistic brain that differs dramatically in structure […]
