Making a mental match: Pairing mechanical device with stroke patients

Making a mental match: Pairing mechanical device with stroke patients

The repetitive facilitation exercise (RFE) is one of the most common rehabilitation tactics for stroke patients attempting to regain wrist movement. Stroke hemiparesis individuals are not able to move that part of their body because they cannot create a strong enough neural signal that travels from the brain to the wrist. With RFE, however, patients get a mental boost. Continue reading

Marijuana dependence alters the brain’s response to drug paraphernalia

Marijuana dependence alters the brain’s response to drug paraphernalia

New research from The University of Texas at Dallas demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users. The study, published July 1 in Drug and Alcohol Dependence , demonstrated that different areas of the brain activated when dependent and non-dependent users were exposed to drug-related cues. The 2012 National Survey on Drug Use and Health shows marijuana is the most widely used illicit drug in the United States. Continue reading

Hidden Variations in Neuronal Networks May Explain Differences In Traumatic Brain Injury Outcomes

Hidden Variations in Neuronal Networks May Explain Differences In Traumatic Brain Injury Outcomes

A team of researchers at the Neuroscience Institute at Georgia State University has discovered that hidden differences in the properties of neural circuits can account for whether animals are behaviorally susceptible to brain injury. These results could have implications for the treatment of brain trauma Continue reading

Study of noninvasive retinal imaging device presented at Alzheimer’s conference

Study of noninvasive retinal imaging device presented at Alzheimer’s conference

A noninvasive optical imaging device developed at Cedars-Sinai can provide early detection of changes that later occur in the brain and are a classic sign of Alzheimer’s disease, according to preliminary results from investigators conducting a clinical trial in Australia. The researchers will present their findings July 15 in an oral presentation at the Alzheimer’s Association International Conference 2014 in Copenhagen, Denmark. Continue reading

DARPA taps Lawrence Livermore to develop world’s first neural device to restore memory

DARPA taps Lawrence Livermore to develop world’s first neural device to restore memory

The Department of Defense’s Defense Advanced Research Projects Agency (DARPA) awarded Lawrence Livermore National Laboratory (LLNL) up to $2.5 million to develop an implantable neural device with the ability to record and stimulate neurons within the brain to help restore memory, DARPA officials announced this week. The research builds on the understanding that memory is a process in which neurons in certain regions of the brain encode information, store it and retrieve it. Certain types of illnesses and injuries, including Traumatic Brain Injury (TBI), Alzheimer’s disease and epilepsy, disrupt this process and cause memory loss. Continue reading

Dodging dots helps explain brain circuitry

Dodging dots helps explain brain circuitry

A neuroscience study provides new insight into the primal brain circuits involved in collision avoidance, and perhaps a more general model of how neurons can participate in networks to process information and act on it. In the study, Brown University neuroscientists tracked the cell-by-cell progress of neural signals from the eyes through the brains of tadpoles as they saw and reacted to stimuli including an apparently approaching black circle. In so doing, the researchers were able to gain a novel understanding of how individual cells contribute in a broader network that distinguishes impending collisions. Continue reading
