The Claim

In male grey mouse lemurs, chronic 30% caloric restriction does not significantly alter performance in spatial memory (Barnes maze) or working memory (spontaneous alternation task) despite accelerated grey matter atrophy in memory-related brain regions.

Description
1 study reviewed
In plain English

In male grey mouse lemurs, a 30% reduction in calorie intake over time does not change performance on tests of spatial or working memory, even though brain regions involved in memory show increased tissue loss.

See the scientific wording

In male grey mouse lemurs, chronic 30% caloric restriction does not significantly alter performance in spatial memory (Barnes maze) or working memory (spontaneous alternation task) despite accelerated grey matter atrophy in memory-related brain regions.

Why this might work

Even though brain cells shrink and die in memory areas, the wiring between brain regions stays intact because the protective insulation around nerve fibers is preserved, allowing signals to travel normally and memory tasks to be performed without decline.

What the research says

1 study
  1. Study: Caloric restriction increases lifespan but affects brain integrity in grey mouse lemur primates

    Even though the lemurs on a low-calorie diet lost more brain tissue in areas used for memory, they still remembered how to navigate mazes and make choices just as well as lemurs eating normally.
