- Some mice are cleverer than others, say US neuroscientists. Their rodent equivalent of an IQ test might fuel the controversial pursuit for genes linked to human intelligence. Scientists have long used a factor called general intelligence or 'g' to rate people's brainpower.

Oct 4, 2024 · Do mice have IQ. Mice may not have an IQ in the same sense as humans do, but they possess remarkable cognitive abilities. They can learn complex mazes, recognize objects, and even display adaptive behavior. So, while we can’t assign them a specific IQ score, mice are certainly not lacking in smarts! How smart is a cat
Aug 8, 2003 · Proficiency on standardized functional tests has been incorporated into a metric commonly referred to as the intelligence quotient (IQ). Matzel et al. have developed a similar performance-based approach to quantifying learning ability and applied it to a sample of 56 genetically heterogeneous mice. They chose five dissimilar tasks (whose ...
Sep 15, 2023 · In a new study that examines learning from reward, MIT researchers deciphered some initially mystifying mouse behavior, yielding new ideas about how mice think and a mathematical tool to aid future research. “I’d like to think mice are smarter than we give them credit for,” Le said.

Goldman’s team extracted immature glial cells from donated human fetuses. They injected them into mouse pups where they developed into astrocytes, a star-shaped type of glial cell. Within a year, the mouse glial cells had been completely usurped by the human interlopers. The 300,000 human cells each mouse received multiplied until they numbered 12 ...
A battery of standard tests for mouse memory and cognition showed that the mice with human astrocytes are much smarter than their mousy peers. In one test that measures ability to remember a sound associated with a mild electric shock, for example, the humanised mice froze for four times as long as other mice when they heard the sound, suggesting t...
“It would be interesting to find out whether the human astrocytes function the same way in the mice as they do in humans,” says Fred Gage, a stem cell researcherat the Salk Institute in La Jolla, California. “It would show whether the host modifies the fate of cells, or whether the cells retain the same features in mice as they do in humans,” he sa...
To explore further how the human astrocytes affect intelligence, memory and learning, Goldman is already grafting the cells into rats, which are more intelligent than mice. “We’ve done the first grafts, and are mapping distributions of the cells,” he says. Although this may sound like the work of science fiction – think Deep Blue Sea, where researc...

Dec 7, 2021 · Mice are very intelligent members of the rodent species, and they can make great pets. They have emotional intelligence and empathy and can use facial expressions to convey how they are feeling. Mice are big on grooming and are good at learning new things.
Oct 14, 2009 · Nature - Researchers have engineered more than 30 strains of 'smart mice', revealing possible ways to boost human brains. But, as Jonah Lehrer finds, cognitive enhancement may come at a cost.
