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.”

Way Too Fascinating

“What all this suggests is that the amygdalae, which are normally thought of as the brain’s “fear” centers, also actually *inhibit* panic attacks.”

“Researchers scare ‘fearless’ patients. Weird science for today. People with amygdala lesions don’t experience fear — they walk in the middle of the street because they are not afraid of getting hit by cars. But if you make them breathe air with extra carbon dioxide, which in normal people just causes them to try to breathe harder, in people with amygdala lesions causes panic attacks.”

“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.”

Scientists have figured out a way to read our dreams. It is in the preliminary stages, but the knowledge base will continue to expand. Although it seems pretty simplistic, it is a phenomenal step in an understanding of what our unconscious mind is up to during the one-third of our lives spent in slumber. Many people report infrequent memories of dream content, while some report no memory whatsoever.
