Better-educated people appear to be significantly more likely to recover from a moderate to severe traumatic brain injury (TBI), suggesting that a brain’s “cognitive reserve” may play a role in helping people get back to their previous lives, new Johns Hopkins research shows.
A novel imaging technique provides insights into the role of redox signaling and reactive oxygen species in living neurons, in real time. Scientists have developed a new optical microscopy technique to unravel the role of 'oxidative stress' in healthy as well as injured nervous systems.
Green tea is said to have many putative positive effects on health. Now, researchers are reporting first evidence that green tea extract enhances the cognitive functions, in particular the working memory. The findings suggest promising clinical implications for the treatment of cognitive impairments in psychiatric disorders such as dementia.
It has long been believed that drinking green tea is good for the memory. Now researchers have discovered how the chemical properties of China's favorite drink affect the generation of brain cells, providing benefits for memory and spatial learning.
For the first time, researchers have demonstrated that narrowing of the carotid artery in the neck without any symptoms may be linked to problems in learning, memory, thinking and decision-making, compared to people with similar risk factors but...
The Third Annual Roots of Empathy Research Symposium (May 7-9, 2014) promises to be yet another thought-provoking gathering in Toronto, Ontario, Canada.
The symposium will offer rich interdisciplinary presentations from expert research scientists on topics such as development of executive function skills, neurophysiological foundations of emotions, attachment, and self-regulation, neuroendocrinology and social behaviour, the psychology,neuroscience, and ethics of empathy, and social and emotional learning in the early years.
Knowing what someone else is feeling plays a fundamental role in interpersonal interactions. In this paper, we articulate evidence from social psychology and cognitive neuroscience, and argue that empathy involves both ...
Alzheimer's disease is the leading cause of dementia and affects some 400,000 people in Spain alone. However, no effective cure has yet been found. One of the reasons for this is the lack of knowledge about the cellular mechanisms which cause alterations in nerve transmissions and the loss of memory ...
A recently FDA-approved device has been shown to reduce seizures in patients with medication-resistant epilepsy by as much as 50 percent. When coupled with an innovative electrode placement planning system developed by physicians at Rush, the device facilitated the complete elimination of seizures in nearly half of the implanted Rush patients enrolled in the decade-long clinical trials.
It has been proposed that green tea extract may have a beneficial impact on cognitive functioning, suggesting promising clinical implications. However, the neural mechanisms underlying this putative cognitive enhancing effect of green tea extract still remain unknown.
This study investigates whether the intake of green tea extract modulates effective brain connectivity during working memory processing and whether connectivity parameters are related to task performance.
Green tea extract increased the working memory induced modulation of connectivity from the right superior parietal lobule to the middle frontal gyrus. Notably, the magnitude of green tea induced increase in parieto-frontal connectivity positively correlated with improvement in task performance.
Our findings provide first evidence for the putative beneficial effect of green tea on cognitive functioning, in particular, on working memory processing at the neural system level by suggesting changes in short-term plasticity of parieto-frontal brain connections. Modeling effective connectivity among frontal and parietal brain regions during working memory processing might help to assess the efficacy of green tea for the treatment of cognitive impairments in psychiatric disorders such as dementia.
(Medical Xpress)—The fruit fly Drosophila melanogaster is a model organism (a non-human species that is extensively studied to understand particular biological phenomena) studied in a wide range of laboratory experiments for several reasons,...
If you are trying to quit smoking one method to incorporate is to do new, exciting "self-expanding" activities that can help with nicotine craving. This is the take-home message from a new study published online in PLOS ONE.
You know when you get a glimpse into someone else’s emotional experience or their pain? You can really feel it for a moment and sometimes it might bring you to tears or motivate you to help someone. That’s empathy.
Overactive empathy, on the other hand, is when you have that experience of opening up to someone else’s emotions and experience, but then instead of coming back to yourself afterwards and being centered in your own needs and feelings, you remain ‘out there’ – absorbed in everyone else’s ‘stuff’. In social situations, you can sense what everyone else is feeling and thinking.
Even walking past people in the street, you can feel and sense what is going on with them. Physical empaths can even pick up physical pains and aches that aren’t theirs.
Overactive empathy can lead to people-pleasing, self-sacrifice and self neglect
