Brain Stimulation to Improve Surgical Skill Learning
March 30, 2020 Check out the cool new findings published in Brain Stimulation from our pre-registered randomized and placebo-controlled trial testing if transcranial direct current stimulation could improve skill learning (Cox et al., in press, and press release from department of Surgery). We used the Fundamental of Laparoscopic Surgery as our training and testing modules and ... it worked... now need to replicate! |

Read All About It! ... Meta-Analysis and Systematic Reviews of Transcranial Magnetic Stimulation
February 29, 2020
We have done deep dives into the TMS literature to see how it is being used to change 'online' behavior (stimulation during tasks) and to determine how stimulation affects connections between brain areas. The results of this deep dive (so far), are a quantitative meta-analysis (Beynel et al 2019) and a systematic review (Beynel et al 2020). Read all about it in the links below.

Congratulations to Edem Asamoa
Feb 15, 2019
Congrats to Edem for winning a 2019 Summer Neuroscience Program award. This award will fund his summer research which builds on our on-going studies testing visual-motor learning in athletes. In particular, he will be combining the Synchrony Light Rail with EEG to develop brain-based biomarkers of anticipatory timing (that will hopefully be used one day to scout professional baseball players).

Our recent Attention, Perception and Psychophysics article is getting quite a bit of press!
In this study we compared action gamers and non-gamers to see if these two groups differed in visual sensory memory (often called Iconic Memory). We found that although gamers don’t retain information for longer than non-gamers do, they do get more visual information from what they’re looking at and had overall better performance across the board. |

Congratulations to our undergraduate Summer Research Fellows
Congratulations to Eliza Gentzler for winning a 2013 Summer Neuroscience Program of Research (NPR) award. Eliza’s proposal is to use EEG to study individual differences in attentional capacity and to relate these differences to other measures of visual perception, psychometrics, and genetics.
Congratulations are also in store for Clara Colombatto and her graduate student mentor Kait Clark for their 2013 Vertical Integration Program award. This prize will fund collaborative research between Clara and Kait to look at how Mindfulness relates to visual perception and action.
We are very excited to have received both of these award in the Opti Lab this summer!!!

Sourcefed Satire on Youtube: Nike Glasses Enhance Memory!
We have been spoofed!!!
Check out this little bit on SourceFed. They seem to be cynical about our funding source. But don’t worry, the defense department is now footing the bill!!! To their credit though, they nailed the recount of our research. If this comedy thing doesn’t work out, they could clearly get jobs as professional science writers.
-- Kudos Lee and Joe!

Second Strobe Training Study in Wall Street Journal: 'Stroboscopic' Memory Enhancement
by Christopher Shea
Playing catch while wearing special “stroboscopic” eyewear can improve short-term memory, according to a study by researchers at the Duke Institute for Brain Sciences.
The eyewear turns a smooth flow of visual information into a series of discrete snapshots (think strobe lights on a dance floor). 100 milliseconds of clear vision alternates with opacity, with the length of the opaque period controllable by the user. The longer the opaque period — things don’t go completely dark but get very gray and hazy — the tougher it is to react to moving objects.
Most participants played catch with a bean-bag ball, for two sessions, but members of Duke soccer and basketball teams also took part in the experiment, doing drills related to those sports. Then, in a laboratory test, participants undertook a memory test that involved recalling which letters had appeared in certain spaces. Relative to a control group that had trained with clear eyewear, students who wore the special glasses performed better after training; this was true whether they headed straight into the lab after training or delayed 24 hours—which is significant because it shows that the memory enhancement was more than fleeting.

Greg Featured in ABC News: Conservatives and Liberals Have Different Brains, Studies Show
by Sydney Lupkin
Conservatives and liberals may have one less thing in common: neurology.
Procon.org has gathered 13 peer-reviewed studies of behavioral and neurological studies and come to the conclusion that differences between Republicans and Democrats are more than skin-deep.
“Basically, the different sides have been yelling at each other for millennia, and we’re trying to figure out what could be the root cause of this,” said Steven Markoff, ProCon.org’s founder.

Strobe Training Study Featured in Popular Science: Nike's New Strobing Glasses Enhance Athletes' Visual Acuity and Sensory Skills
by Clay Dillow
Nike has developed a means of increasing visual short-term memory retention and physical reaction time via a set of strobing goggles that rob athletes in training of some of their vision. The SPARQ Sensory Performance system evaluates an athlete for 10 visual performance skills and creates a training program specifically for him or her that involves wearing Nike’s SPARQ Vapor Strobe Eyewear, which basically fog over to block the wearer’s vision for short periods of time, forcing the athlete to anticipate what’s coming next.
The idea is to fine-tune an athlete’s sensory perception, visual acuity, and the brain’s ability to maintain a precise sense of timing absent a constant stream of visual input. The regimen is backed up by Duke University research that shows that the SPARQ system can indeed heighten visual skills and improve athletes’ reaction times. The system is apparently already in beta with some professional and collegiate sports programs, and will see a worldwide rollout soon.
It’s tough to say at this point how much that improvement translates to the playing field, but Nike isn’t the only entity out there looking for ways to groom the brain into a better tool for physical activity. DARPA and the DoD are constantly on the lookout for technological tools that will help soldiers stay more alert, improve physical reaction times, increase eye-hand coordination, and sharpen decision-making skills on the fly--so the implications for this technology beyond athletic training are certainly real.

Strobe Study Featured in Duke Institute for Brain Sciences Spotlight: Strobe Eyewear Training Improves Visual Memory
By Julie Rhodes
Stroboscopic training, performing a physical activity while using eyewear that simulates a strobe-like experience, has been found to increase visual short-term memory retention, and the effects lasted 24 hours.
Participants in a Duke University study engaged in physical activities, such as playing catch, while using either specialized eyewear that limits vision to only brief snapshots or while using eyewear with clear lenses that provides uninterrupted vision. Participants completed a computer-based visual memory test before and after the physical activities. Research participants came from the Duke community. Many were recruited from University-organized sports teams, including varsity-level players. The study found that participants who trained with the strobe eyewear gained a boost in visual memory abilities.

Greg Featured in USA Today: Babies Try Lip-Reading in Learning to Talk
By Lauran Neergaard
Babies don't learn to talk just from hearing sounds. New research suggests they're lip-readers too.
It happens during that magical stage when a baby's babbling gradually changes from gibberish into syllables and eventually into that first "mama" or "dada."
Florida scientists discovered that starting around age 6 months, babies begin shifting from the intent eye gaze of early infancy to studying mouths when people talk to them.
"The baby in order to imitate you has to figure out how to shape their lips to make that particular sound they're hearing," explains developmental psychologist David Lewkowicz of Florida Atlantic University, who led the study being published Monday. "It's an incredibly complex process."
Apparently it doesn't take them too long to absorb the movements that match basic sounds. By their first birthdays, babies start shifting back to look you in the eye again — unless they hear the unfamiliar sounds of a foreign language. Then, they stick with lip-reading a bit longer.
