‘Neural fingerprints’ of memory associations allow ‘mind reading’

‘Neural fingerprints’ of memory associations allow ‘mind reading’ | Bioquímica | Scoop.it

Researchers have begun to show that it is possible to use brain recordings to reconstruct aspects of an image or movie clip someone is viewing, a sound someone is hearing or even the text someone is reading. A new study by University of Pennsylvania and Thomas Jefferson University scientists brings this work one step closer to actual mind reading by using brain recordings to infer the way people organize associations between words in their memories.

 

Epilepsy patients who volunteered for the study while awaiting brain surgery had tiny electrodes implanted in their brains, which allowed researchers to precisely observe electrical signals that would not have been possible to measure outside the skull. While recording these electrical signals, the researchers asked the participants to study lists of 15 randomly chosen words and, a minute later, to repeat the words back in whichever order they came to mind.

 

The researchers examined the brain recordings as the participants studied each word to home in on signals in the participant’ brains that reflected the meanings of the words. About a second before the participants recalled each word, these same “meaning signals” that were identified during the study phase were spontaneously reactivated in the participants’ brains.

 

Because the participants were not seeing, hearing or speaking any words at the times these patterns were reactivated, the researchers could be sure they were observing the neural signatures of the participants’ self-generated, internal thoughts.

 

Critically, differences across participants in the way these meaning signals were reactivated predicted the order in which the participants would recall the words. In particular, the degree to which the meaning signals were reactivated before recalling each word reflected each participant’s tendency to group similar words (like “duck” and “goose”) together in their recall sequence.

 

Since the participants were instructed to say the words in the order they came to mind, the specific sequence of recalls a participant makes provides insights into how the words were organized in that participant’s memory.

Empirical Data Confirm Autism Symptoms Related to Aluminum and Acetaminophen Exposure

Empirical Data Confirm Autism Symptoms Related to Aluminum and Acetaminophen Exposure | Bioquímica | Scoop.it

Autism is a condition characterized by impaired cognitive and social skills, associated with compromised immune function. The incidence is alarmingly on the rise, and environmental factors are increasingly suspected to play a role.

This paper investigates word frequency patterns in the U.S. CDC Vaccine Adverse Events Reporting System (VAERS) database.

 

Our results provide strong evidence supporting a link between autism and the aluminum in vaccines. A literature review showing toxicity of aluminum in human physiology offers further support.

 

Mentions of autism in VAERS increased steadily at the end of the last century, during a period when mercury was being phased out, while aluminum adjuvant burden was being increased.

 

Using standard log-likelihood ratio techniques, we identify several signs and symptoms that are significantly more prevalent in vaccine reports after 2000, including cellulitis, seizure, depression, fatigue, pain and death, which are also significantly associated with aluminum-containing vaccines.

 

We propose that children with the autism diagnosis are especially vulnerable to toxic metals such as aluminum and mercury due to insufficient serum sulfate and glutathione.

 

A strong correlation between autism and the MMR (Measles, Mumps, Rubella) vaccine is also observed, which may be partially explained via an increased sensitivity to acetaminophen administered to control fever.

Big Pharma Testing Oxycontin On Children as Young as 6 to Keep Patent | Bioquímica | Scoop.it

You’ve likely heard of OxyContin; it’s that heavy duty narcotic painkiller, the one that has spurred the prescription drug addiction problem to new heights over the past several years. Well, the maker of this wonder-drug, responsible for countless overdose deaths, is so concerned with their patent running out, that they’ve decided to test the drug on children as young as six years old.

FDA Confirms Reports of 13 Deaths Possibly Related to Energy Drink

FDA Confirms Reports of 13 Deaths Possibly Related to Energy Drink | Bioquímica | Scoop.it

FDA said it has received reports of 13 deaths since 2008 possibly related to the use of 5-hour Energy shots, a disclosure that could heighten scrutiny of drinks and dietary supplements that promise to deliver an energy..

5-hour Energy, sold in 1.93-ounce plastic bottles, increasingly has become a fixture at check-out counters of convenience stores and drug stores. Its label promises to deliver a boost of energy "in minutes."

In a statement Wednesday, Living Essentials said 5-hour is intended for "busy adults" and that its product is an effective dietary supplement, containing about as much caffeine as a cup of coffee.

It recommends on product labels that consumers don't drink more than two bottles a day, spaced several hours apart, and that consumers sensitive to caffeine should consult with a physician.

"It is important to note that submitting a serious adverse event report to the FDA, according to the agency itself, is not construed by FDA as an admission that the dietary supplement was involved, caused or contributed to the adverse event being reported, or that any person included in the report caused or contributed to the event," the company added in its statement Wednesday.

Living Essentials had about $600 million in sales last year.

God has not made everyone equal, some of them has been gifted with a decent physique but some are not. All those unfortunate ones struggle hard to increase their body weight and at times feel discouraged. As per physicians there can be two key reasons for it, first not feeling hungry and second fat metabolism for more details: http://www.dietkart.com/health-and-nutrition/weight-management/weight-gain
