Researchers Rewrite Textbook on Location of Brain’s Speech Processing Center
New location of critical area provides hints on origin of language. Scientists have long believed that human speech is processed towards the back of the brain’s cerebral cortex, behind auditory cortex where all sounds are received — a place famously known as [Read More]
Making Memories Last
Stowers researchers discovered that a prion-like protein plays a key role in storing long-term memories. Memories in our brains are maintained by connections between neurons called “synapses”. But how do these synapses stay strong and keep memories alive for decades? [Read More]
Study: Men at Higher Risk for Mild Memory Loss than Women
Men may be at higher risk of experiencing mild cognitive impairment (MCI), or the stage of mild memory loss that occurs between normal aging and dementia, than women, according to a study published in the January 25, 2012, online issue of Neurology®, the medical journal of [Read More]
Researchers Induce Alzheimer’s Neurons from Pluripotent Stem Cells
First-ever feat provides new method to understand cause of disease, develop drugs Led by researchers at the University of California, San Diego School of Medicine, scientists have, for the first time, created stem cell-derived, in vitro models of sporadic and hereditary [Read More]
Magic Mushrooms’ Effects Illuminated in Brain Imaging Studies
Brain scans of people under the influence of the psilocybin, the active ingredient in magic mushrooms, have given scientists the most detailed picture to date of how psychedelic drugs work. The findings of two studies being published in scientific journals this week [Read More]
Neural Balls and Strikes: Where Categories Live in the Brain
Brain circuits for visual categorization revealed by new experiments Hundreds of times during a baseball game, the home plate umpire must instantaneously categorize a fast-moving pitch as a ball or a strike. In new research from the University of Chicago, scientists have [Read More]
Brain Glia Cells Increase Their DNA Content to Preserve Vital Blood Brain Barrier
The blood-brain barrier is essential for maintaining the brain’s stable environment — preventing entry of harmful viruses and bacteria and isolating the brain’s specific hormonal and neurotransmitter activity from that in the rest of the body. In addition to nerve [Read More]
Brain Region Can Signal Early Stage Alzheimer’s and Other Dementias
Early changes to the inferior frontal junction observed in early dementias A key misplaced yet again? Unable to recall a name? Forgetfulness frequently leads to anxiety: is it just a sign of age, or are these the first symptoms of the onset of Alzheimer’s disease? It has [Read More]
Receptor for Tasting Fat Identified in Humans
Why do we like fatty foods so much? We can blame our taste buds. Our tongues apparently recognize and have an affinity for fat, according to researchers at Washington University School of Medicine in St. Louis. They have found that variations in a gene can make people more [Read More]
Disruption of Biological Clocks Causes Neurodegeneration, Early Death
New research at Oregon State University provides evidence for the first time that disruption of circadian rhythms – the biological “clocks” found in many animals – can clearly cause accelerated neurodegeneration, loss of motor function and premature death. The study [Read More]
