“When measures are taken that would have made an earlier injury or harm less likely to occur, evidence of the subsequent measures is not admissible to prove:
- negligence;
- culpable conduct;
- a defect in a product or its design; or
- a need for a warning or instruction.
But the court may admit this evidence for another purpose, such as impeachment or–if disputed–proving ownership, control, or the feasibility of precautionary measures.”
An innovative new study merges engineering and clinical expertise to develop a revolutionary method to diagnose and treat epilepsy patients.
Researchers from the University of Minnesota and the Mayo Clinic believe a new type of non-invasive brain scan — taken immediately after a seizure — will provide advanced insight into possible causes and treatments for epilepsy patients.
The new findings could benefit millions of people who are unable to control their epilepsy with medication.
The research is published online in the journal Brain.
Researchers say the study resulted in several significant findings:
“This is the first-ever study where new non-invasive methods were used to study patients after a seizure instead of during a seizure,” said Dr. Bin He, a biomedical engineering professor in the University of Minnesota’s College of Science and Engineering and senior author of the study. “It’s really a paradigm shift for research in epilepsy.”
Epilepsy affects nearly 3 million Americans and 50 million people worldwide. Although medications and other treatments help many people of all ages who live with epilepsy, about 1 million people in the U.S. and 17 million people worldwide continue to have seizures that can severely limit their lives.
Medical researchers have always faced the challenge of determining the part of the brain responsible for the seizures. Learning the specific site of the seizure helps physicians determine the best possible treatment.
In the past, most research has focused on studying patients while they were having a seizure, or what is technically known as the “ictal” phase of a seizure. Some of these studies involved invasive methods such as surgery to collect data.
In the new study, researchers used a novel approach by studying the brains of 28 patients immediately after seizures, or what is technically know as the “postictal” phase of a seizure.
They used a specialized type of non-invasive EEG with 76 electrodes attached to the scalp for gathering data in contrast to most previous research that used 32 electrodes. The researchers used specialized imaging technology to gather data about the patient.
The findings may lead to innovative means of locating the brain regions responsible for seizures in individual patients using non-invasive strategies.

Sleep loss impairs the brain’s ability to integrate appetitive information, and thus makes it more difficult for people to choose healthy foods to eat, according to a study presented at the 26th Annual Meeting of the Associated Professional Sleep Societies.
After a night of sleep deprivation, brain activity in study participants’ frontal lobe was impaired, and networks governing appetitive food stimulus evaluation appeared to be disrupted.
Stephanie Greer, a graduate student at the Sleep and Neuroimaging Laboratory at the University of California, Berkeley, conducted an imaging study to investigate the effect of sleep deprivation on central brain mechanisms underlying food appraisal. She and her colleagues recruited eight healthy adults ages 18 to 25, eight of whom were female, for two MRI sessions during which they rated their current desire for 80 foods. The first session was conducted after a night of normal sleep, and the second was conducted after 24 hours without sleep in a repeated-measures cross-over design. The investigators took subjective taste ratings from the participants after each scan.
“Sleep deprivation selectively and significantly impaired activity in high-order regions known to integrate affective signals, specifically the right anterior insula and dorsal anterior cingulate, in response to desired foods,” said Ms. Greer. She and her colleagues observed equivalent reactivity in classical subcortical reward regions and basic taste-perception networks, such as the medial orbital-frontal cortex, the middle insula, and the caudate.
In addition, sleep deprivation decreased the correlation between food desire and taste ratings. This result, which was consistent with a failure of appetitive signal integration, indicated a decreased ability to determine food desire based on taste value. The researchers did not observe any differences in mean ratings of food desire or taste value.
“These results shed light on how the brain becomes impaired by sleep deprivation, leading to improper food choices,” said Ms. Greer. The study findings also provide a mechanistic brain link between sleep loss and obesity and may be valuable to public health researchers, she added.
