Concussions accelerate Alzheimer's disease-related brain atrophy and cognitive decline, research finds

Concussions accelerate Alzheimer's disease-related brain atrophy and cognitive decline, research finds

New research has found concussions accelerate Alzheimer's disease-related brain atrophy and cognitive decline in people who are at genetic risk for the condition. [More]
Could pathogen infection really lead to Alzheimer’s?

Could pathogen infection really lead to Alzheimer’s?

New concepts of infectious disease are evolving with the realization that pathogens are key players in the development of progressive chronic diseases that originally were not thought to be infectious. Infection is well-known to be associated with numerous neurological diseases for which... [More]
Neuroscientists modify MRI scanner to study workings of infants' brains

Neuroscientists modify MRI scanner to study workings of infants' brains

In adults, certain regions of the brain's visual cortex respond preferentially to specific types of input, such as faces or objects -- but how and when those preferences arise has long puzzled neuroscientists. [More]
Cocaine addicts make riskier decisions than healthy people after losing potential reward

Cocaine addicts make riskier decisions than healthy people after losing potential reward

People addicted to cocaine make riskier decisions than healthy people after losing a potential reward, according to a study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. [More]
EMBL scientists trace neural connections that control instinctive behaviours

EMBL scientists trace neural connections that control instinctive behaviours

From fighting the urge to hit someone to resisting the temptation to run off stage instead of giving that public speech, we are often confronted with situations where we have to curb our instincts. [More]
Cell powerhouses may be good therapeutic target for brain injury

Cell powerhouses may be good therapeutic target for brain injury

Cell powerhouses are typically long and lean, but with brain injury such as stroke or trauma, they can quickly become bloated and dysfunctional, say scientists who documented the phenomena in real time for the first time in a living brain. [More]
Mediterranean diet may help provide long-term protection to the brain

Mediterranean diet may help provide long-term protection to the brain

A new study shows that older people who followed a Mediterranean diet retained more brain volume over a three-year period than those who did not follow the diet as closely. [More]
Study finds evidence for unique electrical properties of human pyramidal neurons

Study finds evidence for unique electrical properties of human pyramidal neurons

The human brain's advanced cognitive capabilities are often attributed to our recently evolved neocortex. [More]
Witnessing fear in others may change how information flows in the brain, study finds

Witnessing fear in others may change how information flows in the brain, study finds

Scientists at the Virginia Tech Carilion Research Institute have discovered that observing fear in others may change how information flows in the brain. [More]
New TSRI study sheds light on how the brain stores memories

New TSRI study sheds light on how the brain stores memories

A new study led by scientists at The Scripps Research Institute (TSRI) sheds light on how the brain stores memories. [More]
Specific gene pathway appears to regulate growth, structure, and organization of cerebral cortex

Specific gene pathway appears to regulate growth, structure, and organization of cerebral cortex

One of the most significant ways in which the human brain is unique is the size and structure of the cerebral cortex. But what drives the growth of the human cortex, likely the foundation for our unique intellectual abilities? [More]
Researchers explore how neuronal activity influences CREB dynamics

Researchers explore how neuronal activity influences CREB dynamics

Neuronal activity mediates the formation of neuronal circuits in the cerebral cortex. These processes are regulated by the transcription factor CREB, which regulates gene expression in neuronal activity-dependent processes. [More]
Study identifies new mechanism of how inhibitory brain cells develop

Study identifies new mechanism of how inhibitory brain cells develop

Scientists have discovered that networks of inhibitory brain cells or neurons develop through a mechanism opposite to the one followed by excitatory networks. [More]
Tau biomarker could lead to early identification of Alzheimer's disease pathology

Tau biomarker could lead to early identification of Alzheimer's disease pathology

A discovery of high relevance in medical research will be published in Volume 55, number 4 of December 2016 of the prestigious "Journal of Alzheimer's Disease (JAD)", entitled "Tau Platelets Correlate with Regional Brain Atrophy in Patients with Alzheimer's Disease". [More]
Neuroscientists uncover how the brain retunes to pull meaning out of noisy environment

Neuroscientists uncover how the brain retunes to pull meaning out of noisy environment

When you're suddenly able to understand someone despite their thick accent, or finally make out the lyrics of a song, your brain appears to be re-tuning to recognize speech that was previously incomprehensible. [More]
Research provides insights into how exposure to certain stimuli facilitates occurrence of epileptic seizures

Research provides insights into how exposure to certain stimuli facilitates occurrence of epileptic seizures

Why does exposure to rhythmic stimulation at certain frequencies facilitate the occurrence of epileptic seizures? In 1997, flickering patterns in an episode of the series Pokémon triggered epileptic seizures in nearly 700 Japanese children. [More]
Researchers pinpoint mechanism underlying astrocyte-mediated recovery of brain tissue after injury

Researchers pinpoint mechanism underlying astrocyte-mediated recovery of brain tissue after injury

A Kobe University research team has pinpointed the mechanism underlying astrocyte-mediated restoration of brain tissue after an injury. This could lead to new treatments that encourage regeneration by limiting damage to neurons incurred by reduced blood supply or trauma. [More]
Endurance runners' brains have greater functional connectivity, research shows

Endurance runners' brains have greater functional connectivity, research shows

If you're thinking about taking up running as your New Year's resolution and still need some convincing, consider this: MRI scans reveal that endurance runners' brains have greater functional connectivity than the brains of more sedentary individuals. [More]
MGH researchers develop magnetic coils for selective and reliable neural stimulation

MGH researchers develop magnetic coils for selective and reliable neural stimulation

Massachusetts General Hospital researchers have developed what appears to be a significant improvement in the technology behind brain implants used to activate neural circuits responsible for vision, hearing or movement. [More]
Psychiatrist explains how the brain blocks memory to help get through traumatic event

Psychiatrist explains how the brain blocks memory to help get through traumatic event

Everyone has done something they probably want to forget—falling face first on the stage at your high school graduation or asking a woman how far along she is only to find out she isn't even pregnant. [More]
