Researchers have created unusually intelligent mice by altering a single gene and as a result the mice were also less likely to feel anxiety or recall fear.
The study, led by the University of Leeds and Mount Sinai Hospital in Toronto, is published today in the journal Neuropsychopharmacology.
It sheds light on the molecular underpinnings of learning and memory and could form the basis for research into new treatments for age-related cognitive decline, cognitive disorders such as Alzheimer’s disease and schizophrenia, and other conditions.
