Scientists shed new light on how the brains process visuals we don’t know we’ve seen

first_imgShare on Facebook Share LinkedIn A team of scientists has mapped out how our brains process visuals we don’t even know we’ve seen, indicating that the neuronal encoding and maintenance of subliminal images is more substantial than previously thought.“Our results indicate that what is ‘invisible’ to the naked eye can, in fact, be encoded and briefly stored by our brain,” observes Jean-Rémi King, a postdoctoral fellow in NYU’s Department of Psychology and one of the researchers.The co-authors of study, which appears in the journal Neuron, also include Niccolo Pescetelli, a doctoral student at the University of Oxford, and Stanislas Dehaene, a professor at Collège de France. Share on Twittercenter_img Email In their study, human subjects viewed a series of quickly flashed images, and reported which ones they saw and which they could not see, while their brain activity was monitored using magnetoencephalography (MEG)–a non-invasive neuroimaging technique which makes, at every millisecond, multiple measurements of the tiny magnetic fields generated by the neuronal activity. Critically, the authors developed machine learning algorithms to decode the content of these images directly from these large and complex neuroimaging data.These new algorithms allowed the authors to confirm a series of theoretical predictions. In particular, they reveal a striking dissociation between the dynamics of “objective” (i.e. the visual information presented to the eyes) and “subjective” neural representations (i.e. what subjects report having seen). However, and contrarily to theoretical predictions, the authors also showed that invisible images can be partially maintained within high-level regions of the brain.“Undoubtedly, these results suggest that our current understanding of the neural mechanisms of conscious perception may need to be revised,” notes King, who also holds an appointment at the Frankfurt Institute for Advanced Studies (FIAS). “However, beyond our empirical findings, this study demonstrates that machine learning tools can be remarkably powerful at decoding neuronal activity from MEG recordings–a preview of what we can uncover about the workings of the brain.” Pinterestlast_img read more

USA: Corps Introduces Jacksonville Harbor Dredging Program

first_imgU.S. Army Corps of Engineers, Jacksonville District, has introduced a plan for the Jacksonville Harbor area dredging program.This deepening work is located in the upper cuts through the Lower Terminal Channel of Jacksonville Harbor, Duval County, Florida.The base work under this contract includes maintenance dredging in the 40-foot project from Cut-41 through the Lower Terminal Channel.All dredged material will be placed in Cell F of East Bartram Island.The total cost is between $5 mln and $10 mln, and the proposals will be due on or about 13 August 2013.More info[mappress]Source: fbo.gov, July 26, 2013last_img

No. 19 UWF Sweeps No. 17 Nova Southeastern

The Argos avenged last season’s 2-3 loss to Nova at the South Region finals, and were led by juniors Chelsea Wilhoite (Jacksonville, Fla./Bishop Kenny HS) and Jamie Nichols (Crawfordville, Fla./Wakulla HS) with 12 kills each. “That’s a monkey we’ve had on our back for 292 days, and I couldn’t be happier about earning the right to let it. It doesn’t take last year away, but it takes a little bit of the bite away,” said head coach Melissa Wolter.“I thought for the first time since we’ve come together as a group, that was the most confident and relaxed that I’ve seen our team play,” commented Wolter. “We talked in the locker room before the match about outplaying Nova, and I think defensively we did exactly that. We dug some balls tonight that I have not seen our team dig since we started the season.”Wilhoite swung at .385 on the match, while Patricia Gandolfo (Porto Alegre, Brazil/Missouri State-West Plains CC) posted a .400 clip on nine kills. Kara Gonzalez (St. Augustine, Fla./St. Augustine HS) had an outstanding match tallying eight kills at .300, stuffing her opponents on five occasions. Kimberly Clark (St. Petersburg, Fla./Hillsborough CC) led with 17 digs, as Tricia Tirabassi (Kenosha, Wis./Tremper HS) dished out 34 assists. The Argos as a whole outhit the Sharks .275 to .175. The Sharks put the first point on the board, but West Florida took a solid lead on a three point service run by Nichols. Nova made several comeback attempts, but the Argos controlled the remainder of the set and closed out on a service ace by Gonzalez.NSU again took the first point in set two, but this time took a lead that looked to be out of the Argos’ reach. A Wilhoite kill gave UWF the serve at 14-17, and the team chipped away at the lead and tied on Wilhoite’s ace. The teams battled to 23-23, and the Argos took advantage of a Sharks’ service error that led to a victory on a kill from Nichols. The Argos found themselves in a familiar 2-0 situation, and surrendered the first three points to Nova. West Florida, however, took a 9-8 lead on the swing of Gandolfo and never looked back. The Argos’ offense came alive, and the Sharks appeared to fall apart as Nichols again went three-point service run that included an ace. UWF cruised to a 25-17 win, and sealed the match on a block by Gonzalez and Clark. West Florida continues action in the Hemingway’s Regional Crossover on Friday, playing their first match of the day against No. 5 Tampa at 2pm. The Argos will finish the day at 7pm, facing region opponent Saint Leo. Both matches will be available online through live stats and broadcast. Print Friendly Versionlast_img read more
