Researchers in Montreal say they could be close to developing a memory pill after identifying a gene mutation that affects the memory of mice.
The discovery was made when the scientists say they suppressed the activity of the gene in mice before they swam around a water-maze, noting that the altered mice performed better.
But when the gene's activity was increased, the performance of memory was worse.
The scientists hope to find molecules that target and inhibit the gene, which is also thought to exist in humans.
Doctors say this could ultimately lead to a memory enhancing pill.
