Scientists have identified a unique form of cell messaging occurring in the human brain, revealing just how much we still have to learn about its mysterious inner workings.
Brains – especially those of the human variety – are often compared to computers.
While the team had carried out similar experiments on rats, the kinds of signals they observed buzzing through the human cells were very different.
More importantly, when they dosed the cells with a sodium channel blocker called tetrodotoxin, they still found a signal.
In addition to the logical AND and OR-type functions, these individual neurons could act as 'exclusive' OR (XOR) intersections, which only permit a signal when another signal is graded in a particular fashion.
