notes The Rose that Grew from Concrete

Did you hear about the rose that grew
from a crack in the concrete?
Proving nature’s law is wrong it
learned to walk with out having feet.
Funny it seems, but by keeping it’s dreams,
it learned to breathe fresh air.
Long live the rose that grew from concrete
when no one else ever cared.

"Essentially, the brain did not evolve for culture, but culture evolved to be learnable by the brain. Through its cultural inventions, humanity constantly searched for specific niches in the brain, wherever there is a space of plasticity that can be exploited to “recycle” a brain area and put it to a novel use. Reading, mathematics, tool use, music, religious systems — all might be viewed as instances of cortical recycling."

notes How the Brain Filters out Distracting Thoughts

guerrillas:

Researchers at the Kavli Institute for Systems Neuroscience and Centre for the Biology of Memory at the Norwegian University of Science and Technology (NTNU) have discovered a mechanism that the brain uses to filter out distracting thoughts to focus on a single bit of information.

The brain’s nerve cells are able to “tune in” to the right station to get exactly the information they need, says researcher Laura Colgin, who was the paper’s first author. “Just like radio stations play songs and news on different frequencies, the brain uses different frequencies of waves to send different kinds of information,” she says.

Information is carried on top of gamma waves, just like songs are carried by radio waves. These “carrier waves” transmit information from one brain region to another. “We found that there are slow gamma waves and fast gamma waves coming from different brain areas, just like radio stations transmit on different frequencies.”

“You know how when you feel like you really connect with someone, you say you are on the same wavelength? When brain cells want to connect with each other, they synchronize their activity,” Colgin explains. “The cells literally tune into each other’s wavelength. We investigated how gamma waves in particular were involved in communication across cell groups in the hippocampus. What we found could be described as a radio-like system inside the brain. The lower frequencies are used to transmit memories of past experiences, and the higher frequencies are used to convey what is happening where you are right now.”

“The cells can rapidly switch their activity to tune in to the slow waves or the fast waves,” Colgin says, “but it seems as though they cannot listen to both at the exact same time.”
