Cocaine Exposure can Alter Neuronal Development in Zebrafish

...sociate professor in the department of anatomy and neurobiology at BUSM. Thus the circadian system might be at the core of the developmental effects of cocaine and their inter-individual variability, she added. According to Zhdanova, circadian factors, including melatonin, could provide new therapeutic stra...

UCLA Imaging Study Reveals How Pure Oxygen Harms the Brain

...xplained Ronald Harper, distinguished professor of neurobiology at the David Geffen School of Medicine at UCLA. "What we discovered adds to a compelling body of evidence for modifying a widely practiced standard of care in the United States." Harper's team used functional magnetic resonance imaging (fMRI) to ca...

Appetite-regulating Peptides Influence Alcohol Cravings

...involvement of appetite-regulating peptides in the neurobiology of alcohol craving is of different importance in specific subgroups," said Hillemacher. The researchers also stressed the need for the identification of subgroups of alcoholics for future studies as well as clinical applications. "Our findings ...

Brain Cells Activity: New Treatment Target for Psychiatric Diseases

...suppress it," says Dr. Mei, chief of developmental neurobiology at MCG. "Now we have identified another novel target of neuregulin-1 which is the inhibitory synapse." Together the findings reveal a check and balance for brain cell activity managed by neuregulin-1 in the brain's prefrontal cortex, where complex ...

Bird Song Study Provides Clues to Human Speech Disorders

...ular speech problem. But, if we can understand the neurobiology of the brain of this animal model and how sounds are processed by birds that produce normal and variant songs, then we may be able to translate these findings into treatments for patients with disorders such as stuttering and verbal dyspraxia," said ...

Link Between Food Cue-related Brain Activity Found

...ing, can influence food intake. But the underlying neurobiology is far from clear. Craig A. Schiltz and colleagues from the University of Wisconsin Madison School of Medicine and Public Health, USA, created an experimental set up that allowed them to study patterns of gene expression linked to this motivational s...

Tai Chi - More Than Magic

...Monjan, chief of the National Institute on Aging's neurobiology of aging branch. "It seems to be somewhat more effective than simple exercise and more effective than simple stress reduction." And older adults enjoy it, he said, making it a therapy patients will stick to. For healthy older adults, the study dem...

New Light on Working of Brain Networks

...acting stimuli,” said Amy Arnsten, lead author and neurobiology professor at Yale. The brain’s prefrontal cortex (PFC) normally is responsible for so-called executive functions. The ability of the PFC to maintain such memory-based functions declines with normal aging, is weakened in people with ADHD, and is sev...

Brain Networks Strengthened by Closing Ion Channels

...acting stimuli,” said Amy Arnsten, lead author and neurobiology professor at Yale. The brain’s prefrontal cortex (PFC) normally is responsible for so-called executive functions. The ability of the PFC to maintain such memory-based functions declines with normal aging, is weakened in people with ADHD, and is sev...

To Remember Or Not - Brain Protein CREB Calls The Shots

... Says lead researcher Alcino Silva, professor of neurobiology and psychiatry at UCLA's David Geffen School of Medicine, after confirming tests on mice: “Making a memory is not a conscious act. Learning triggers a cascade of chemicals in the brain that influence which memories are kept and which are lost.” CREB...

Robotic Therapy Helps Restore Hand Use After Stroke

... and associate professor in neurology, anatomy and neurobiology at UCI. “Robot-assisted therapy may help rewire the brain and make weak limbs move better long afterwards.” Previously, robotic devices have improved post-stroke shoulder and leg function. Cramer said this study is one of the first attempts to spec...

Ultrasound Technology - Boon or a Bane?

...nd, a recent study by Pasko Rakic, chairman of the neurobiology department at Yale University School of Medicine says that exposure to ultrasound can affect foetal brain development. But it does not mean that the use of ultrasound on human foetuses for appropriate diagnostic and medical purposes be abandoned. ...

Learning Slows Physical Progression of Alzheimer's Disease: Study

...gnitive decline," said Frank LaFerla, professor of neurobiology and behavior and co-author of the study. "These...." LaFerla; James McGaugh, research professor of neurobiology and behavior; and postdoctoral researchers Kim Green and Lauren Billings studied hundreds of mice be...

Nicotine Dependence Gene Mapped to Chromosome 5

...l Gelernter, professor of psychiatry, genetics and neurobiology and lead author of the study. “The chromosome 5 linkage signal is our most remarkable result statistically.” He said the finding is significant since any ability to predict nicotine dependence based on genes that influence risk could be useful and m...

How Many Genes Does It Take to Learn? Lessons from Sea Slugs

...ence. "We took advantage of this powerful model of neurobiology and identified thousands of genes operating within a single neuron. Just during any simple event related to memory formation, we expect differences in gene expression for at least 200 to 400 genes." Researchers studied gene expression in associatio...

The Pain from Fibromyalgia Is Real, Researchers Say

...ter. A growing amount of research related to the neurobiology of this condition supports the notion that the pain of fibromyalgia is real. Studies at U-M and elsewhere using two neuroimaging techniques – functional magnetic resonance imaging (fMRI) and single photon emission computed tomography (SPECT) – indica...

Gene Variant associated with Schizophrenia identified

... gene causes schizophrenia so as to understand the neurobiology of the disorder and design treatments that could reduce the symptoms." Marjorie Wallace, chief executive of the mental health charity Sane, said: "There have been so many hopes of finding a gene for schizophrenia which have ended in a cul-de-sac. ...

New foetal scans are misleading

.... " Dr Huseyin Mehmet, a reader in developmental neurobiology at Imperial College London, said, "A foetal brain at 23 and 24 weeks is extremely immature and it is like an orange that has been sliced in half. " But Julia Millington, of the Pro-Life Alliance, said, "It is irrelevant whether someone looking at t...

Stress Could Have A Notable Effect In Quickening The Progression Of Alzheimer's disease

...to the research led by Frank LaFerla, professor of neurobiology and behaviour, and a team of researchers from UC I...her, and Benno Roozendaal, assistant researcher in neurobiology and behaviour, managing stress and reduction of certain medications that are prescribed for the elde...

Patients With Major Depression Have An Overstated Inflammatory response to Stress

...ontribution of early life abuse and neglect to the neurobiology of adulthood psychiatric disorders. Ongoing studies by Dr. Miller's team of researchers will attempt to determine how early life experiences contribute to excessive inflammatory stress responses. “According to the Depression and Bipolar Support All...
