How Exposure to Brief Trauma and Sudden Sounds Form Lasting Memories

Aug. 24, 2015 — Researchers have found how even brief exposure to sudden sounds or mild trauma can form permanent, long-term brain connections, or memories, in a specific region of the ... read more

Physical Activity Linked to Greater Mental Flexibility in Older Adults

Aug. 24, 2015 — One day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their ... read more

Food Intake, a Fragile Balance Between Neural Pathways

Aug. 24, 2015 — Scientists investigated the relative role of energy needs and "pleasure" of eating in food intake. The researchers studied a group of neurons in mice. They observed that when the neuron ... read more

Activated Neurons Produce Protective Protein Against Neurodegenerative Conditions

Aug. 24, 2015 — Activated neurons produce a protein that protects against nerve cell death. Researchers have found out how this effect comes about and defined a crucial ... read more

Aug. 20, 2015 — Two proteins that share the ability to help cells deal with their trash appear to need each other to do their jobs and when they don't connect, it appears to contribute to development of ... read more

Brief Postnatal Blindness Triggers Long-Lasting Reorganization in the Brain

Aug. 20, 2015 — A brief period of postnatal visual deprivation, when early in life, drives a rewiring of the brain areas involved in visual processing, even if the visual restoration is completed well before the ... read more

New Insights in Pathological Mechanism That Causes Dysfunctional Synapses

Aug. 19, 2015 — Genetic analysis of human patients has shown that mutations in genes involved in synaptic communication can drive neuropsychiatric and neurological diseases such as autism spectrum disorder and ... read more

Study Reveals Effects of Chemoradiation in Brains of Glioblastoma Patients

Aug. 17, 2015 — A new study -- the first to examine the effects of combined radiation and chemotherapy on the healthy brain tissue of glioblastoma patients -- reveals not only specific structural changes within ... read more

Study Identifies Cause of Disruption in Brain Linked to Psychiatric Disorder

Aug. 17, 2015 — New research has identified the mechanisms that trigger disruption in the brain's communication channels linked to symptoms in psychiatric disorders including schizophrenia. This research could ... read more

Aug. 17, 2015 — Every brain cell has a nucleus, or a central command station. Scientists have shown that the passage of molecules through the nucleus of a star-shaped brain cell, called an astrocyte, may play a ... read more

Aug. 17, 2015 — In the summer of 2012, Olga Kotelko, a 93-year-old Canadian track-and-field athlete with more than 30 world records in her age group, submitted to an in-depth analysis of her brain. The resulting ... read more

Aug. 17, 2015 — Certain diseases, like Parkinson's and Huntingdon's disease, are associated with damage to the pathways between the brain's basal ganglia regions. For the first time, scientists have ... read more

Imaging Study Looks at Brain Effects of Early Adversity, Mental Health Disorders

Aug. 17, 2015 — Adversity during the first six years of life was associated with higher levels of childhood internalizing symptoms, such as depression and anxiety, in a group of boys, as well as altered brain ... read more

Aug. 17, 2015 — Scientists have revealed never-before-seen details of how our brain sends rapid-fire messages between its cells. They mapped the 3-D atomic structure of a two-part protein complex that controls the ... read more

How Anesthesia's Brain Effects Differ in Older Adults, Children

Aug. 13, 2015 — A series of papers is detailing the different ways common anesthetics affect the brains of older patients and children, findings that could lead to improved monitoring technology and safety of ... read more

Aug. 13, 2015 — Neuroscientists have discovered how an animal's biological clock wakes it up in the morning and puts it to sleep at night. In studies of fruit flies and mice and the brain circadian neurons ... read more

Regenerating Nerve Tissue in Spinal Cord Injuries

Aug. 13, 2015 — Researchers are exploring a new therapy using stem cells to treat spinal cord injuries within the first 14 to 30 days of injury. The therapy uses a population of cells derived from human embryonic ... read more
