New Video on Dana Alliance Member Wendy Suzuki

The Huffington Post recently published an article on neuroscientist Wendy Suzuki, highlighting her research on exercise and the brain. She is a Dana Alliance member and professor of neural science and psychology at New York University. In the article, Suzuki says:

Exercise is not going to cure Alzheimer’s or dementia but it anatomically strengthens two of the key targets of both diseases, the hippocampus and the prefrontal cortex. Your hippocampus will be bigger if you exercise regularly, so that means that it’s going to take that much longer for the plaques and tangles of Alzheimer’s disease to cause behavioral effects.

For a detailed look into her lab and research, watch the video below. To read the full Huffington Post article, click here.

Facial Cues and the Brain

As human beings, we can tend to be a little judgmental–sometimes without even realizing it. When we first meet someone, our brains are busy processing facial features, body language, personality traits, etc., within milliseconds of just saying “hello.” So what characteristics make us assume certain things about people we just meet, and can these unconscious first impressions really change the way we perceive someone?

Expanding on this topic, neuroscientist Jon Freeman, Ph.D., spoke to a room crowded with eager listeners as the featured guest in the latest event from the Secret Science Club. As director of the Social Cognitive & Neural Sciences lab at New York University, Freeman devotes all of his research to understanding “split-second social perception”—that is, how our brains use subtle facial cues, personality traits, and emotion to instantly categorize others into social groups. With the help of brain imaging technology (fMRI), electrophysiology (EEG and ERP), and real-time behavioral techniques, Freeman is able to study activity within the brain in hopes of learning more about the phenomena of snap judgments.

The Spooky Neuroscience Behind Fear and Zombies

Halloween is the one time of year that we seek out scary situations. Some people decorate their houses like a creepy lab or cemetery, others go to haunted houses to see classic monsters and gory scenarios. We dress up like witches, devils, vampires, zombies, and other creatures of the night. What causes us to seek out these frightful situations? Why are we afraid of what we see? What happens when we look at these scary creatures with a scientific lens?

These spooky questions inspired the latest Halloween themed Taste of Science, formerly Pint of Science, a series of science lectures over beers at Ryan’s Daughter bar in Manhattan. Nathan H. Lents, Ph.D., discussed fear and Erin Coffey, Ph.D., examined the science behind a monster that many of us fear, zombies.

The Anxious Brain

“Since the 1960s, billions of dollars and probably millions of animals have gone into the search for new and better anti-anxiety medications,” said researcher Joseph LeDoux at an event this week on anxiety at the American Association for the Advancement of Science. But drug makers, who have spent years targeting points along a brain pathway described as the “fear circuit” in animals, haven’t had the success they sought; they have stopped funding many studies. Why?

LeDoux, a Dana Alliance member at New York University who has studied this circuit for the past three decades, argues that the term we use may have blinded us to what the circuit actually does. Instead of labeling it with a human feeling, it would better to call it an unconscious “defensive survival circuit.” Other inputs lead to the conscious feelings of fear and anxiety. For example, while hiking, we have already recoiled from the snake on the trail before our conscious minds have hit the danger signal. The two things happen so fast, though, it’s easy to think the feeling led to the action—but we’re committing the first sin of science: confusing correlation and causation, LeDoux said.

What We Can Learn from the Minds of Olympic Athletes: Q&A with John Krakauer, M.D.

Guest blog by Kayt Sukel

The famed Olympic torch is now burning strong in Rio de Janeiro. The 2016 Summer Olympics are under way, and the best athletes in the world have come to represent their respective countries and compete for the gold. Time and time again, sports commentators regale us with stories about the necessity of a good “mental” game to find success in high profile events like the Olympics–and the scientific research, though limited, appears to back that view [See our paper: “Mental Preparation of High-Level Athletes”]. But what is it specifically about the brains of these athletes that allows them to reach these levels? John Krakauer, M.D., a neurologist at the Johns Hopkins University who studies human sensorimotor learning and performance, speaks with us about what we can learn from the minds of Olympic athletes, whether super athletes should be considered geniuses, and how those findings may one day inform rehabilitation after stroke or brain injury.
