Researchers reveal an unexpected connection between the lateral hypothalamus and the hippocampus, the respective feeding and the memory centers of the brain.
Early adult general cognitive ability is a stronger predictor of cognitive function and reserve later in life than other factors, such as higher education, occupational complexity or engaging in late-life intellectual activities.
A protein-secreting device implanted into the hippocampus of epileptic rats reduces seizures by 93 percent in three months, finds preclinical research published in JNeurosci. These results support ongoing development of this technology and its potential translation into a new treatment for epilepsy.
Researchers have identified a cellular response to repeated concussions that may contribute to seizures in mice like those observed following traumatic brain injury in humans. The study, published in JNeurosci, establishes a new animal model that could help improve our understanding of post-traumatic epilepsy.
Today's main hypothesis about the cause of autism symptoms is that neurons receive too little inhibition or too much excitation, causing hyperexcitability. This excessive spiking interferes with normal brain function. UC Berkeley neuroscientists demonstrated that while inhibition does decrease in the brains of mice models, the changed balance between excitation and inhibition doesn't affect spiking. The altered balance seems to be a compensatory mechanism that stabilizes brain activity in response to the disorder.
Our brains seem to reduce sensory perception from an area of our skin when we touch it ourselves, according to a new study from Linköping University, Sweden, published in the journal Proceedings of the National Academy of Sciences, PNAS. The finding increases our understanding of how the brain distinguishes between being touched by another person and self-touch.
A simple blood test reliably detects signs of brain damage in people on the path to developing Alzheimer's disease -- even before they show signs of confusion and memory loss, according to a new study from Washington University School of Medicine in St. Louis and the German Center for Neurodegenerative Diseases.
Scientists at the German Center for Neurodegenerative Diseases, the Hertie Institute for Clinical Brain Research and the University Hospital Tuebingen show that a protein found in the blood can be used to precisely monitor disease progression of Alzheimer's long before first clinical signs appear. This blood marker offers new possibilities for testing therapies. The study was carried out in cooperation with an international research team and published in the journal Nature Medicine.
A natural immune system response may be responsible for inflicting additional harm in the weeks and months after a spinal injury.
A new study identifies the neurons in the human visual cortex that selectively respond to faces. The researchers showed that the neurons in the visual cortex (in the vicinity of the Fusiform Face Area) responded much more strongly to faces than to city landscapes or objects. In an additional experiment, the neurons exhibited face-selectivity to human and animal faces that appeared within a movie. The results provide unique insights into human brain functioning at the cellular level during face processing.
