Every time an external force severely injures the brain – whether through a car accident, fall, war injury, or sports trauma – it leaves a lasting impact. For people with traumatic brain injury (TBI), one of the leading causes of death and injury worldwide, depression is a common symptom, occurring in half of all patients. […]
Guest Post by Lisa Qu, Northwestern University Smelling a cup of freshly brewed coffee can be a rich, almost magical, experience. In fact, in that brief moment, you are smelling a mixture of more than 800 different molecules that make up the smell of coffee. Part of what makes that experience so rich also makes […]
Teenagers like to explore and push boundaries but not all exploration is the same. Neuroscientists have yet to fully distinguish between risk-taking, for example, as compared with strategically exploring novel experiences. A new study shows marked differences in brain activity among individual teens who are more or less exploratory. The work could help shape future […]
Guest Post by Chris Forsythe, Sandia National Laboratories Being an applied neuroscientist, I was stunned as I skimmed my daughter’s 7th grade life science textbook and found that only 8 out of 400 pages discussed the nervous system. This amounted to one section of one chapter. In contrast, while genetics are certainly important, there were […]
Our day-to-day lives can be thought of as a battle on the neural level. We have tons of stimuli fighting for our attention and of those, only a few will stick. I am often surprised by which things stick in my memory for the long-term, a particular shirt I wore or a line from a […]
It’s breakfast time, and you head to the fridge to grab some orange juice but just as you go to pour it into your cup, you hear someone calling to you, turn toward the sound, and pour it into your cereal bowl instead or maybe even onto the floor. We’ve all been there – had […]
For the past 15 years, researchers have been studying the effects of neglect on the developing brain through the study of Romanian orphans. The work has spawned dozens of papers, and even a book, detailing the profound consequences of early institutionalization on brain and behavior development. In one of the latest studies, researchers found that […]
For parents of deaf children, deciding whether to get a cochlear implant can be tough. The great hope is that an implant will help deaf children gain oral language skills. Behavioral data has suggested that congenitally deaf children best receive implants by age 4, but little has been known about how they perceive their first […]
Loneliness is not something trivial to ignore; it is an important health issue at the heart of emotional distress syndromes. A growing body of research is illuminating the evolutionary roots of loneliness and how those feelings interact with our social environment. In a new study, researchers found that lonely people’s brains perceive social threats automatically […]
In our daily lives, we are all constantly setting goals, whether to go to the gym more or to save up for a vacation. In creating goals, some people more specifically outline the steps to get there than others. Those different approaches to planning engage different structures in the brain, according to a new study, […]
