“Scientists have traced vulnerability to depression-like behaviors in mice to out-of-balance electrical activity inside neurons of the brain’s reward circuit and experimentally reversed it…Instead of suppressing it, researchers..boosted runaway neuronal activity even further, eventually triggering a compensatory self-stabilizing response. Once electrical balance was restored, previously susceptible animals were no longer prone to becoming withdrawn, anxious, and listless following socially stressful experiences.”
more severe crimes are often thought of as deserving more severe punishments, since they are thought to result from free will…currently working on a study that may demonstrate that people who believe in free will feel less anxious punishing others.”
When public support for gun control peaked after the Newtown mass murder, the National Rifle Association (NRA) decided to double down.
The necessary corollary to the NRA pitch is that anyone who does kill with a gun must have been “crazy.” So the solution to the violence problem is not to control the guns—instead, it is to identify and control the crazy people who are the only ones who misuse them.
The National Rifle Association propaganda has it all wrong. Most violent acts are committed by people who are not crazy.
Only one thing is predictable with statistical certainty. If there are more guns in the schools, streets, offices, military bases, and homes, more of them will be fired and more people will be killed.
The use of the term “conscious” here is suspect, but….
“Is our perceptual experience of a stimulus entirely determined during the early buildup of the sensory representation, within 100 to 150 ms following stimulation? Or can later influences, such as sensory reactivation, still determine whether we become conscious of a stimulus?
Late visual reactivation can be experimentally induced by postcueing attention after visual stimulus offset. In a contrary approach from previous work on postcued attention and visual short-term memory, which used multiple item displays, we tested the influence of postcued attention on perception, using a single visual stimulus (Gabor patch) at threshold contrast. We showed that attracting attention to the stimulus location 100 to 400 ms after presentation still drastically improved the viewers’ objective capacity to detect its presence and to discriminate its orientation, along with drastic increase in subjective visibility. This retroperception effect demonstrates that postcued attention can retrospectively trigger the conscious perception of a stimulus that would otherwise have escaped consciousness.
It was known that poststimulus events could either suppress consciousness, as in masking, or alter conscious content, as in the flash-lag illusion. Our results show that conscious perception can also be triggered by an external event several hundred ms after stimulus offset, underlining unsuspected temporal flexibility in conscious perception.”
