Specific Brain Region Plays Important Role In Reducing Anxiety
2013-03-07 09:13:26

April Flowers for redOrbit.com - Your Universe Online A research team led by the Columbia University Medical Center (CUMC) has found the first evidence that selective activation of the dentate gyrus, a portion of the hippocampus, can reduce anxiety without affecting learning. The findings suggest therapies targeting this brain region could treat certain anxiety disorders, such as panic disorder and post-traumatic stress syndrome (PTSD). These treatments, as described in the study, would...

Researchers identify the novel expression of an ion channel in neurons of the brain Research at the University of Calgary's Hotchkiss Brain Institute (HBI) has demonstrated the novel expression of an ion channel in Purkinje cells — specialized neurons in the cerebellum, the area of the brain responsible for movement. Ray W. Turner, PhD, Professor in the Department of Cell Biology & Anatomy and PhD student Jordan Engbers and colleagues published this finding in the January edition...

When it comes to the circuits that make up the olfactory system, it seems that less is more. Much like the addition and elimination of extra synapses that helps fine-tune brain circuitry, the olfactory system continues to produce and remove neurons throughout life. Yet it is not entirely clear how and why some newborn neurons are preserved while others are eliminated. Now, new research published by Cell Press in the September 8 issue of the journal Neuron reveals that both olfactory...

Selective serotonin reuptake inhibitors (SSRI) such as Prozac are regularly used to treat severe anxiety and depression. They work by immediately increasing the amount of serotonin in the brain and by causing long term changes in brain function. However it can take weeks of treatment before a patient feels any effect and both beneficial effects and side effects can persist after treatment is stopped. New research published by BioMed Central's open access journal Molecular Brain investigates...

(Ivanhoe Newswire) -- The brain makes mistakes and then corrects them, according to a new study. A research group, led by Dr. Peter Scheiffele at the Biozentrum of the University of Basel, was able to document the brain's process of establishing a neuronal network that does not always prove precise or error-free. In the developing brain, countless nerve connections are made, which turn out to be inappropriate, and as a result, must eventually be removed. Using a genetic mouse model, the...

In the developing brain, countless nerve connections are made which turn out to be inappropriate and as a result must eventually be removed. The process of establishing a neuronal network does not always prove precise or error free. Dr. Peter Scheiffele's research group at the Biozentrum of the University of Basel have been able to document this phenomenon using advanced microscopy techniques in the developing cerebellum, a brain area required for fine movement control. Dr. Scheiffele's group...

St. Jude Children's Research Hospital scientists identify a novel feedback mechanism that regulates differentiation of adult neural stem cells St. Jude Children's Research Hospital investigators showed a gene named Prox1 is a key player in normal development of a brain structure crucial for learning and memory and remains active throughout life, nurturing the cells vital for making new memories. This study focused on a small region of the hippocampus known as the dentate gyrus, a brain...

Ben W. Strowbridge, PhD, associate professor of neuroscience and physiology/biophysics, and Phillip Larimer, PhD, a MD/PhD student in the neurosciences graduate program at Case Western Reserve University School of Medicine, are the first to create stimulus-specific sustained activity patterns in brain circuits maintained in vitro. Their study, entitled, "Representing information in cell assemblies: Persistent activity mediated by semilunar granule cells" will be published in the February 2010...

Study in Nature Neuroscience uncovers possible basis of memories for different smells Ben W. Strowbridge, Ph.D, associate professor of Neuroscience and Physiology/Biophysics, and Yuan Gao, a Ph.D. student in the neurosciences program at Case Western Reserve University School of Medicine, are the first to discover a form of synaptic memory in the olfactory bulb, the part of the brain that processes the sense of smell. Their study, entitled "Long-term plasticity of excitatory inputs to granule...

"Remember when"¦?" is how many a wistful trip down memory lane begins. But just how the brain keeps tabs on what happened and when is still a matter of speculation. A computational model developed by scientists at the Salk Institute for Biological Studies now suggests that newborn brain cells"”generated by the thousands each day"”add a time-related code, which is unique to memories formed around the same time."By labeling contemporary events as similar, new neurons allow us...

The cerebellum is a section of the brain that is most in charge of cognitive functions and motor skills. Formation and Orientation The cerebellum can be found at the bottom of the brain behind the pons and below that cerebral cortex under a layer of dura mater. It is considered as a part of the "hindbrain". The cerebellum is anatomically divided into two separate hemispheres, marked by the 'vermis', a small midline zone between the left and right hemispheres. But three lobes can be...
