Sundown Syndrome-Like Symptoms in Fruit Flies May Be Due to High Dopamine Levels Changes in Flies Parallel Human Disorder

Perelman School of Medicine at the University of Pennsylvania

Researchers have discovered a mechanism involving the neurotransmitter dopamine that switches fruit fly behavior from being active during the day (diurnal) to nocturnal. This change parallels a human disorder in which increased agitation occurs in the evening hours near sunset and may also be due to higher than normal dopamine levels in the brain.

Mild Traumatic Brain Injury May Alter the Brain’s Neuronal Circuit Excitability and Contribute to Brain Network Dysfunction

Virginia Commonwealth University (VCU)

Even mild head injuries can cause significant abnormalities in brain function that last for several days, which may explain the neurological symptoms experienced by some individuals who have experienced a head injury associated with sports, accidents or combat, according to a study by Virginia Commonwealth University School of Medicine researchers.

Researchers Identify Genetic Mutation Causing Rare Form of Spinal Muscular Atrophy

Cedars-Sinai

Scientists have confirmed that mutations of a gene are responsible for some cases of a rare, inherited disease that causes progressive muscle degeneration and weakness: spinal muscular atrophy with lower extremity predominance, also known as SMA-LED.

Response to First Drug Treatment May Signal Likelihood of Future Seizures in People with Epilepsy

American Academy of Neurology (AAN)

How well people with newly diagnosed epilepsy respond to their first drug treatment may signal the likelihood that they will continue to have more seizures, according to a study published in the May 9, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Cellist Achieves Optimal Performance Through Neurofeedback

Allen Press Publishing

“Practice makes perfect,” the saying goes. Optimal performance, however, can require more than talent, effort, and repetition. Training the brain to reduce stress through neurofeedback can remove barriers and enhance one’s innate abilities.

Deep Brain Stimulation May Hold Promise for Mild Alzheimer’s Disease

Johns Hopkins Medicine

A study on a handful of people with suspected mild Alzheimer’s disease (AD) suggests that a device that sends continuous electrical impulses to specific “memory” regions of the brain appears to increase neuronal activity. Results of the study using deep brain stimulation, a therapy already used in some patients with Parkinson’s disease and depression, may offer hope for at least some with AD, an intractable disease with no cure.

Robot Reveals the Inner Workings of Brain Cells

Georgia Institute of Technology, Research Communications

Researchers have automated the process of finding and recording information from neurons in the living brain. A robotic arm guided by a cell-detecting computer algorithm can identify and record from neurons in the living mouse brain with better accuracy and speed than a human experimenter.

Rats Recall Past to Make Daily Decisions

University of California, San Francisco (UCSF)

UCSF scientists have identified patterns of brain activity in the rat brain that play a role in the formation and recall of memories and decision-making. The discovery, which builds on the team’s previous findings, offers a path for studying learning, decision-making and post-traumatic stress syndrome.
