Babies who had heard the recordings showed the neural signal for recognizing vowel and pitch changes in the pseudoword, and the signal was strongest for the infants whose mothers played the recording most often. They were also better than the control babies at detecting other differences in the syllables, such as vowel length. “This leads us to believe that the fetus can learn much more detailed information than we previously thought,” Partanen says, and that the memory traces are detectable after birth.”This is a well-respected group and the effects are really convincing,” says Patricia Kuhl, a neuroscientist at the University of Washington in Seattle. Combined with previous work, she says, these results suggest “that language learning begins in the womb.”

Depression induced or cured within 10 seconds in rats by turning on or off neurons that release dopamine in the ventral tegmental area of the brain with the help of optogenetics (previously changing neurons to make them be turned on or off by focusing light on them). 10 seconds is shorter than the time that antidepressants usually take to work, which is some weeks. Treatment with magnesium may work within one week, and could be combined for best results with vitamin D, vitamin B12, folic acid, and omega-3.

“Now, it should be noted that the researchers aren’t trying to emulate a complete honey bee brain, but rather two specific and complex functions within it, namely vision and sense of smell.”

“By isolating and modeling these particular functions, the researchers hope to provide their flying robot with the cognitive power required to perform basic tasks — and without a set of pre-programmed instructions. It is hoped, for example, that the robotic bee will be able to detect particular odors or gasses in the same way that real bee can identify certain flowers.”

The system was still able to identify which animal had been named, despite being trained with patterns generated for English words. For example, the word “horse” and its Dutch equivalent “paard” gave rise to the same brain pattern, suggesting that the activity represented the word’s meaning – the concept of a horse. 

However, the brain patterns that Correia identified were unique to each person. Brains are like faces – the eyes, nose and mouth are all in the same place, but the details can be different, says Davis. “The meanings might be stored in the same area, but the actual neurons would be idiosyncratic.” To read someone’s mind, a machine would first need to learn that individual’s unique representation of each word. “You would have to scan a person as they thought their way through a dictionary,” says Davis.

P
eople aren’t really stupid.

These people are not stupid. These people were well educated and intellectually groomed. Stupid isn’t the right word for these people.

These people were susceptible. Their individual and collective egos were reaching up towards an ideal which held them as superior beings.

I proffer that this type of egoic reaction is somewhat involuntary. Many are able to resist the enticement of superiority, or worship, of self-aggrandizement, but eventually all but the rarest of creatures gives way and wallows within the hope of it.

I think it is a security vulnerability in the software of the human brain. Just as we rush to prepare patches to shore up the vulnerabilities on our technological counterparts, so, too, could we rush to prepare a patch for this paradigm shifting vulnerability which has been repeatedly exploited throughout history by those who have a clear understanding of how it works.
