Neuroscientists studying the olfactory -- sense of smell -- system in mice have discovered that fear reaction can occur at the sensory level, even before the brain has the opportunity to interpret that the odor could mean trouble.
Blessed with the power of echolocation -- reflected sound -- bats rule the night skies. And while it seems that echolocation works together with normal vision to give bats an evolutionary edge, nobody knows exactly how. Now research suggests that bats use vision to keep track of where they're going and echolocation to hunt tiny insects that most nocturnal predators can't see. The findings add to scientific understanding of sensory evolution.
Researchers have shown that optogenetics -- a technique that uses pulses of visible light to alter the behavior of brain cells -- can be as good as or possibly better than the older technique of using small bursts of electrical current. Optogenetics had been used in small rodent models. Research has shown that optogenetics works effectively in larger, more complex brains.
A new study suggests that political bias can influence how people perceive the facial characteristics of a presidential candidate -- even after seeing his face on TV thousands of times.
People who are part of a congregation's largest racial group are more likely to feel they belong and be more involved -- regardless of whether their group is barely half or nearly all of the members.
A new test should help doctors to decrease the risk of suicidality in patients treated with antidepressants who show certain gene markers. Researchers plan to launch the test immediately as a laboratory developed test. In addition, clinical studies in support of a U.S. Food and Drug Administration submission for market clearance, CE marking and reimbursement will be initiated.
Repeated blows to the head during a season of contact sports may cause changes in the brain's white matter and affect cognitive abilities even if none of the impacts resulted in a concussion.
Though it has been embraced by everyone from advocates for arts education to parents hoping to encourage their kids to stick with piano lessons, two new studies show no effect of music training on the cognitive abilities of young children.
Scientists have discovered how to fix sleep disturbances in mice with traumatic brain injuries -- a discovery that could lead to help for hundreds of thousands of people who have long-term and debilitating sleep and wakefulness issues after they suffer concussions.
Differences in educational achievement owe more to genetics than environment, finds study of UK students
The degree to which students' exam scores differ owes more to their genes than to their teachers, schools or family environments, according to new research. The study, which took place in the UK, looked at students' scores for their GCSE's (General Certificate of Secondary Education), a UK-wide examination at the end of compulsory education at 16 years old.
Researchers have made strides in staying ahead of Huntington’s disease, a devastating, incurable disorder that results from the death of certain neurons in the brain.
Smokers who are addicted to cocaine or methamphetamine can quit smoking while being treated for their stimulant addiction, without interfering with stimulant addiction treatment, according to new research.
A biology student spent the past few summers developing an experiment for observing the brain's cellular response to a concussion. The never-before-seen action could one day lead to therapies that mitigate brain damage following mild traumatic brain injuries.
In new research, neuroscientists find that even high-performing schools don't influence their students' abstract reasoning.
Understanding the science behind pain, from a simple "ouch" to the chronic and excruciating, has been an elusive goal for centuries. But now, researchers are reporting a promising step toward studying pain in action. In a study published, scientists describe the development of a new technique, which they tested in rats, that could result in better ways to relieve pain and monitor healing.
A new study by Canadian researchers may pave the way for more effective treatment of an aggressive and deadly type of brain tumor, known as ETMR/ETANTR. The tumor, which is seen only in children under four, is almost always fatal, despite aggressive treatment. The study proposes a new model for how this brain tumor develops and suggests possible targets to investigate for novel therapies.
In the first study to look at racial and ethnic differences in dementia risk among older adults with Type 2 diabetes, researchers found that dementia was much higher among Native-Americans and African-Americans and lowest among Asian-Americans.
A mechanism in the brain that controls tics in children with Tourette Syndrome has been discovered by scientists.
A scientist makes a definitive case against spanking, including how it slows cognitive development and increases antisocial and criminal behavior.
In a study published, researchers found that when celebrities publicly discuss their struggles with cancer diagnoses, the resulting media coverage prompts more smokers to search for information on quitting than events like New Year's Day or World No Tobacco Day.
