FORT WAYNE, Ind. (www.incnow.tv) -- In this week's episode of Cool Science Monday, Martin Fisher from Science Central talks about the traveling exhibition, Wild Minds.
Martin showed a display case with brains of various species. Brains are made of specialized cells, called neurons. Humans have about 90 billion neurons. Dolphins and chimpanzees have about 25 billion. Neurons are needed for cognition, the term scientists use for thinking. Some animal species, not all, have been found to have cognition – problem-solving, tool use, self-identification, etc.
