Studying mice, scientists at Johns Hopkins have fortified evidence that a key purpose of sleep is to recalibrate the brain cells responsible for learning and memory so the animals can "solidify" lessons learned and use them when they awaken -- in the case of nocturnal mice, the next evening.
Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses – the junctions between nerve cells - grow strong and large during the stimulation of daytime, then shrink by nearly 20 percent while we sleep, creating room for more growth and learning the next day.
In a new study, Yale Cancer Center researchers identified a novel genetic defect that prevents brain tumor cells from repairing damaged DNA.

PHOENIX – Mayo Clinic researchers have found that engaging in mentally stimulating activities, even late in life, may protect against new-onset mild cognitive impairment, which is the intermediate stage between normal cognitive aging and dementia. The study found that cognitively normal people 70 or older who engaged in computer use, craft activities, social activities and playing games had a decreased risk of developing mild cognitive impairment. The results are published in the Jan. 30 edition of JAMA Neurology.
No single neuron produces a thought or a behavior; anything the brain accomplishes is a vast collaborative effort between cells. When at work, neurons talk rapidly to one another, forming networks as they communicate. Scientists at the Research Institute of Molecular Pathology (IMP) in Vienna and the Rockefeller University in New York are developing technology that would make it possible to record brain activity as it plays out across these networks.
The ancient impulse to procreate is necessary for survival and must be hardwired into our brains. Now scientists from the University of North Carolina School of Medicine have discovered an important clue about the neurons involved in that wiring.
Biologists at The Scripps Research Institute (TSRI) have identified a brain hormone that appears to trigger fat burning in the gut. Their findings in animal models could have implications for future pharmaceutical development.
UNC School of Medicine researchers crystalized the structure of LSD attached to a human serotonin receptor of a brain cell, and they may have discovered why an “acid trip” lasts so long.
Reliable assessment of comatose patients in intensive care units is critical to the patients’ care. Providers must recognize clinical status changes quickly to undertake proper interventions. But does the provider need to be in the same room as the patient, or can robotic telemedicine be used successfully to complete the assessment? According to a research study conducted at Mayo Clinic Hospital in Arizona, published in Telemedicine and e-Health, the answer is yes.
Patterns of brain responses to rewards are a significant predictor of pain symptoms—a link that is already present by adolescence—and may be influenced by gene variants affecting pain sensitivity, reports a study in PAIN®, the official publication of the International Association for the Study of Pain (IASP). The journal is published by Wolters Kluwer.
The shape of your brain can influence personality traits, according to a new study published in the journal Social Cognitive and Affective Neuroscience.
An important step in planning tumor surgery includes assessing the tumor stiffness to aid in surgical planning. Because tumors within the skull cannot be examined non-invasively, researchers used Magnetic Resonance Elastography (MRE) to assess pituitary tumor stiffness. MRE reliably identified tumors that were soft enough for removal with a minimally-invasive suction technique versus harder tumors requiring more invasive surgery.
Parkinson’s disease (PD) and other “synucleinopathies” are known to be linked to the misfolding of alpha-synuclein protein in neurons. Less clear is how this misfolding relates to the growing number of genes implicated in PD through analysis of human genetics. Researchers affiliated with Whitehead Institute and Massachusetts Institute of Technology (MIT) explain how they used a suite of novel biological and computational methods to shed light on the question.
For many families, normal activities, such as going to a large family gathering or an amusement park, can be difficult to navigate with a child with autism, as the child may be act out due to being overwhelmed by extra noises and stimulation. To help families deal with such situations, specialists at the University of Missouri Thompson Center for Autism and Neurodevelopmental Disorders have been successfully integrating applied behavior analysis (ABA), the science of understanding why people behave in various ways and how understanding those motivations can shape behavior.
The UNC School of Medicine has awarded the 17th Perl-UNC Neuroscience Prize to David Anderson, PhD, the Seymour Benzer Professor of Biology at the California Institute of Technology for “his discovery of neural circuit mechanisms controlling emotional behaviors.”
