Readers build vivid mental simulations of narrative situations, brain scans suggest
EurekAlert! Thu, 29 Jan 2009 6:03 AM PST
( Washington University in St. Louis ) A brain-imaging study is shedding light on what it means to "get lost" in a good book -- suggesting that readers create vivid mental simulations of the sounds, sights, tastes and movements described in a textual narrative while simultaneously activating brain regions used to process similar experiences in real life. |
Memories 'Time-stamped' By Newborn Brain Cells
Medical News Today Thu, 29 Jan 2009 5:22 AM PST
"Remember when…?" is how many a wistful trip down memory lane begins. But just how the brain keeps tabs on what happened and when is still a matter of speculation. |
Working Artificial Nerve Networks Created By Weizmann Institute Scientists
Medical News Today Thu, 29 Jan 2009 7:22 AM PST
Scientists have already hooked brains directly to computers by means of metal electrodes, in the hope of both measuring what goes on inside the brain and eventually healing conditions such as blindness or epilepsy. In the future, the interface between brain and artificial system might be based on nerve cells grown for that purpose. |
In Sleep Deprivation Astrocytes Regulate Sleep Pressure And Memory Deficits
Medical News Today Thu, 29 Jan 2009 6:19 AM PST
Scientists have discovered an unexpected brain mechanism that modulates the regulation of sleep and the consequences of sleep deprivation. The research, published by Cell Press in the January 29th issue of the journal Neuron, opens new avenues for development of treatments for disorders and cognitive deficits associated with sleep loss. |
Study Confirms Memories Change Over Time
Psych Central Thu, 29 Jan 2009 6:56 AM PST
A new brain imaging study illustrates what happens to memories as time goes by. The study shows that distinct brain structures are involved in recalling recent and older events. The findings support earlier studies of memory-impaired patients with damage limited to the hippocampus. These patients show deficits in learning new information and in recalling events that occurred [...] |
Surprising Discoveries Contribute To Memory Research
Medical News Today Thu, 29 Jan 2009 6:22 AM PST
Like countless neuroscientists around the world, Northwestern University Professor Nelson Spruston knew H. M. well -- his personal story and the sound of his voice. But it wasn't until H. M. died last month that Spruston learned H. M.'s full name -- Henry Gustav Molaison. In 1953, Molaison, aged 27, had brain surgery to control his severe epilepsy. |
NICE Issues Guidance On FES For Dropped Foot
Medical News Today Thu, 29 Jan 2009 5:19 AM PST
NICE (the National Institute for Health and Clinical Excellence) has issued guidance that says FES (functional electrical stimulation) is safe and can be considered for use in the NHS as a treatment for dropped foot. Dropped foot can occur when nerve messages to the leg are interrupted by damage to the brain or spinal cord. |
Discovery Of First Gene For Most Common Form Of Epilepsy
Medical News Today Thu, 29 Jan 2009 5:21 AM PST
An international team of researchers, led by investigators at Columbia University Medical Center, has uncovered the first gene linked to the most common type of epilepsy, called Rolandic epilepsy. One out of every five children with epilepsy is diagnosed with this form, which is associated with seizures starting in one part of the brain. |
