You need to look into what is called Non-Leathal, it is used by the Police & Military it cab do all that and much more, I can not look into it, myself, as i am under a investigation, and they make sure that I can not get a hold of dam near anything i need, that is unless it has the ability to make me look crazy or paranoid, thus your post, lol. But if you really want to do that kind of thing, and work, you really should look into Non-Leathal

Your article was AWESOME !!! Posted it on Facebook :)
P.S. NO I do not think that you are in on ANYTHING with the FBI over my case, they just make sure that I find things like this, lol, Sigh :(

Why are people left or right-handed? Mystery deepens as brain not the source of asymmetry

Left or right-handedness may arise in the spinal cord and not the brain.
Sandeep Gautam's insight:
Interesting research. We knew that even in left handed people , brain asymmetries like language specialization in left brain , was just like in normal people. This new finding explains much as to how handedness may arise early as a result of spinal cord asymmetry.

What's going on inside the brains of animals? Can we know what, or if, they're thinking and feeling? Carl Safina thinks we can. Using discoveries and anecdotes that span ecology, biology and behavioral science, he weaves together stories of whales, wolves, elephants and albatrosses to argue that just as we think, feel, use tools and express emotions, so too do the other creatures – and minds – that share the Earth with us.

Confirms my hunch that those who pump weights are less brainier overall:-)
John Parkinson's curator insight, September 8, 2016 1:32 PM

The study suggests that 'stress' prevents the potential benefits from exercise. In their study the weight training and high intensity training produced more physical/physiological stress than the running condition.

 

If we define stress as 'uncontrollable aversive stimulation' then it is not a surprising finding.  Whether weight training and HIT also produce increased physiological challenge in humans is not necessarily universally true and probably depends on an individual's approach. Nevertheless, a primary message we can take from this is to balance how much stress your training is having on your body... and always remember to keep smiling...

Your brain can reveal who your true friends are: Study shows how similar neural responses predict friendships

Your brain can reveal who your true friends are: Study shows how similar neural responses predict friendships | Cognitive Neuroscience | Scoop.it
The brains of close friends react to the world in similar ways, so does this mean we form natural echo chambers?

 

You may have a lot of things in common with your friends and brain activity could be one of them. According to a new study that investigated the neural responses of those in real-world social networks, you are more likely to perceive the world in the same way your friends do and this can be seen in patterns of neural activity.

 

The investigation by scientists at Dartmouth College, published today inNature Communications, examined the brains of 42 first-year graduate students, monitoring their responses to a collection of video clips. What they found was that close friends within this group had the most similar neural activity patterns, followed by friends-of-friends, then friends-of-friends-of-friends. The less subjects identified as friends, the more different their neural responses tended to be.

 

"Neural responses to dynamic, naturalistic stimuli, like videos, can give us a window into people's unconstrained, spontaneous thought processes as they unfold,” says lead author Carolyn Parkinson, who at the time of the study was a postdoctoral fellow in psychological and brain sciences at Dartmouth. “Our results suggest that friends process the world around them in exceptionally similar ways."

 

The 42 students were part of a 279-person cohort that filled out a survey to glean who they considered friends in the year group. The researchers gauged closeness based on mutually expressed friendships, and used this to estimate social distances between individuals. The selection of 42 subjects were each shown a range of videos, covering everything from politics to comedy, to elicit a variety of responses.

 

The fact friends tended to neurologically respond similarly suggests these people perceive the world in similar ways. “Whether we naturally gravitate towards people who perceive, think about and respond to things like we do or whether we become more similar over time, through shared experiences, we don't know,” notes Thalia Wheatley, co-author of the study and an associate professor of psychological and brain sciences at Dartmouth.

Friends show similar neural activity; also good to remember that it has been earlier shown that friends share more genes than would be expected by chance.

The Challenge of Consciousness

The Challenge of Consciousness | Cognitive Neuroscience | Scoop.it
Riccardo Manzotti: For most people “consciousness” will have various meanings and include awareness, self-awareness, thinking in language. But for philosophers and neuroscientists the crucial meaning is that of feeling something, having a feeling you might say, or an experience. It’s all very problematic. The truth is that we do not know what consciousness is. That’s why we’re talking about it as a problem.
