Why do we make bad choices, when we "know better?" We see rain clouds in the sky but we don’t take an umbrella to work. More seriously, we marry someone who’s an alcoholic or drug addict, even though we know it’s a mistake. Acknowledged killers who have murdered their wives and are on death row get large numbers of marriage proposals from lonely women. Neurobiologists say that the brain remembers, even if we don’t. But aren’t our brains really us?

Researcher Adam Messinger compares it to subliminal knowledge, which is there, even the information doesn’t enter our consciousness. An example? "You know you?ve met the wife of your work colleague but you can’t recall her face."

Scientists have discovered that marijuana doesn?t just get you “high,” it actually stimulates brain growth. They want to find a way to use it to treat anxiety and depression, since some scientists believe that depression can begin when too few new brain cells are grown in the hippocampus. It may eventually be used as part of a program to treat Alzheimer’s or dementia, diseases that are becoming more common as the population ages.

The key ingredient is the chemical HU-210. Neuropsychiatrist Xia Zhang says the synthetic version is 100 times as powerful as THC, that ingredient in natural marijuana. She says, “This is a very potent cannabinoid oil. It’s not something that would be available on the street.”

The human brain is still evolving and becoming larger, according to researchers who have analyzed two genes that regulate brain size. These genes, associated with larger brain size, appeared at about the same times as the emergence of culture, agriculture, and written language in human populations. On the other hand, researchers have also discovered that brain size alone does not necessarily determine intelligence, because while bird brains are tiny, parrots are some of the most intelligent creatures on this planet.

Newswise – Ancient, preliterate cultures kept their legends and traditions alive with the use of memorization. Many lengthy poems and epics that were eventually written down, such as the works of Homer in ancient Greece, were memorized first. Scholars think that many parts of the Bible were kept in memory for a considerable amount of time before being set down in writing. There?s one way in which we still rely on memorization: the alphabet song. A version of this little tune exists in almost every culture that has an alphabet, and it’s essential to teaching children (and illiterate adults) to read.
