Sustained Aerobic Exercise Increases Adult Neurogenesis in Brain

Feb. 8, 2016 — It may be possible to increase the neuron reserve of the hippocampus – and thus improve preconditions for learning – by promoting neurogenesis via sustained aerobic exercise such as running, say ... read more

Cocaine Users Present Alterations in Function, Structures of Brain

Feb. 8, 2016 — The presence of alterations in brain functioning and structure in cocaine users has been seen in a new study where researchers used three different magnetic resonance imaging techniques to study the ... read more

The Significance of Non-Motor Microtubule-Associated Protein in Maintaining Synaptic Plasticity Thorough a Novel Mechanism

Feb. 5, 2016 — NMDA glutamate receptors, which function as receptors that bond with glutamates, are known to be deeply involved in animal memory and learning. In order for memories to be created inside the brain, ... read more

Feb. 5, 2016 — Neurobiologists have demonstrated experimentally that aggression has an influence on the production of new nerve cells in the brain. The scientists conducted a series of experiments on male ... read more

First-of-Its-Kind Study Explains Why Rest Is Critical After a Concussion

Feb. 5, 2016 — Neuroscientists say rest -- for more than a day -- is critical for allowing the brain to reset neural networks and repair any short-term injury. This new study in mice also shows that repeated mild ... read more

Feb. 5, 2016 — Children with Down syndrome who have motor speech deficits have been inadequately diagnosed, which could have a major impact on the interventions used by speech pathologists when treating patients, a ... read more

Scientists Find Brain Plasticity Assorted Into Functional Networks

Feb. 4, 2016 — Scientists had thought that most synapses of a similar type and in a similar location in the brain behaved in a similar fashion with respect to how experience induces plasticity. In this work, ... read more

Feb. 4, 2016 — In a new study, researchers show that a particular protein found in the brains of both male and female mice is present at higher levels in females, which offers them stronger protection against one ... read more

Neurobiological Changes Explain How Mindfulness Meditation Improves Health

Feb. 4, 2016 — New research provides a window into the brain changes that link mindfulness meditation training with health in stressed adults. The study shows that mindfulness meditation training, compared to ... read more

New Non-Invasive Form of Vagus Nerve Stimulation Works to Treat Depression

Feb. 4, 2016 — Depression can be a devastating and unremitting problem. Researchers now report successful reduction of depressive symptoms in patients using a novel non-invasive method of vagus nerve stimulation, ... read more

Head Injury Patients Develop Brain Clumps Associated With Alzheimer’s Disease

Feb. 3, 2016 — Scientists have revealed that protein clumps associated with Alzheimer's disease are also found in the brains of people who have had a head ... read more

Brain Formation Pattern Shows Why Early Trauma May Leave No Clues

Feb. 3, 2016 — Early nerve networks set patterns in the developing brain, but are then replaced by more mature networks that convert sensory information into thoughts, a new study ... read more

Location May Be Key to Effectively Controlling Pain

Feb. 3, 2016 — In real estate, location is key. It now seems the same concept holds true when it comes to stopping pain. New research indicates that the location of receptors that transmit pain signals is important ... read more

Feb. 2, 2016 — Abnormalities in embryonic brain development in mice, including transient embryonic brain enlargement during neuron formation, are responsible for abnormal adult brain structures and behavioral ... read more

Technique Helps Predict Likelihood of Migraines in Concussion Patients

Feb. 1, 2016 — Researchers are using a mathematical tool to help determine which concussion patients will go on to suffer migraine headaches, according to a new ... read more

Targeting Upper Motor Neurons to Treat ALS

Feb. 1, 2016 — Scientists have demonstrated for the first time that it is possible to specifically modify gene expression in diseased upper motor neurons, brain cells that break down in ALS. The study provides ... read more

Insulin-Like Growth Factor Linked to Hippocampal Hyperactivity in Alzheimer's Disease

Feb. 1, 2016 — The insulin-like growth factor 1 receptor (IGF-1R), the 'master' lifespan regulator, plays a vital role in directly regulating hippocampal hyperactivity in the brain, report scientists. The ... read more

Feb. 1, 2016 — Understanding how the brain folds could help unlock the inner workings of the brain but the process has long remained a mystery. Now, by replicating a folding human brain in 3D, researchers have ... read more
