Epigenetics change which genes are active and which are inactive. Research over the past few years has shown that these changes are important for protecting the brain from neurodegeneration and injury. A review paper came out on May 18th in the journal Nature Reviews Neuroscience that summarizes this research. Check out the infographic for a description of the review paper.
America feels like it’s unraveling.
And science is holding on by a thread.
The first human magnetic resonance imaging (MRI) scan was acquired almost 40 years ago. The scanner — hand-built by Dr. Raymond Damadian with the help of his two postdoctoral fellows — took nearly five hours to produce one snapshot of the human chest, and Dr. Damadian was eventually awarded the National Medal of Technology for his accomplishment.
Sometimes it’s hard to understand why scientists do what they do. Why spend a career studying cells, fungus, or flies? Other than being nerdy and wanting to learn about our world, what’s the point?Continue reading
A kid stealing candy in a convenience store grows up to be a convicted criminal. A husband who flirts with a coworker ends up as a serial cheater. A politician telling a few “white lies” to his or her constituents is eventually convicted of fraud. These are all extreme — but plausible — scenarios where dishonesty might escalate over time, resulting in dramatic and life-changing consequences. But how far does this slippery slope actually go? How can science help us answer this question?Continue reading
We are excited to announce that we received the Society for Neuroscience 2016 Next Generation Award. This award recognizes SfN chapter members who have made outstanding contributions to public communication, outreach, and education about neuroscience. To celebrate the award reflecting our dedication to neuroscience education, we, the team members of Knowing Neurons, reminisce over some of their favorite moments in the past year.Continue reading
Cute things are usually vulnerable, fragile and weak. But cuteness itself is mighty indeed. Morten L. Kringelbach and his colleagues at the University of Oxford recently described cuteness as ‘one of the most basic and powerful forces shaping our behavior.’ And yet, despite its elemental importance, cuteness might be a fluid, evolving concept and trait.Continue reading
Consider three scenarios. A kid joins a new high school and eats lunch by herself. A recently separated man is alone for the New Year’s Eve countdown. A prisoner becomes aggravated in a solitary confinement cell. The common thread that runs through these disparate experiences is the universal feeling of loneliness.Continue reading
It is no surprise that a child prefers its mother’s voice to those of strangers. Beginning in the womb, a fetus’s developing auditory pathways sense the sounds and vibrations of its mother. Soon after birth, a child can identify its mother’s voice and will work to hear her voice better over unfamiliar female voices. A 2014 study of preterm infants showed that playing a recording of the mother’s voice when babies sucked on a pacifier was enough to improve development of oral feeding skills and shorten their hospital stay. A mother’s voice can soothe a child in stressful situations, reducing levels of cortisol, the stress hormone, and increasing levels of oxytocin, the social bonding hormone. Scientists have even traced the power of a mother’s voice to infants’ brains: a mother’s voice activates the anterior prefrontal cortex and the left posterior temporal region more strongly than an unfamiliar voice, priming the infant for the specialized task of speech processing.
While it makes intuitive sense that a mother’s voice has special power over infants and toddlers, what happens as children grow up? Continue reading
If you grew up with siblings, it is likely that you have heard the phrase, ”Imitation is the sincerest form of flattery.” However, it wasn’t until a groundbreaking finding in the 1990s that the neural correlate to imitation was discovered in a class of neurons called mirror neurons.

We all know too much sugar is bad for us. But did you know that having unfettered access to sugar might produce brain changes similar to highly stressful situations, such as neglect or abuse? A recent study published in Frontiers in Molecular Neuroscience comparing the effects of unlimited sugar availability and the effects of early life stress in rats might suggest just that.Continue reading
If you’re in a room with ten adults, chances are two of them are going to develop a mental illness –- and only one of them will receive proper treatment. Depending upon the psychiatric condition, common treatments include psychotherapy, cognitive behavioral therapy, and pharmacotherapy. Continue reading
