Summary
Female mice exhibit superior cognitive flexibility compared to males, demonstrating faster learning and quicker decision-making after rule shifts. This sex difference in cognitive flexibility may offer insights into neuropsychiatric conditions.
Area of Science:
- Neuroscience
- Behavioral Science
- Computational Psychiatry
Background:
- Cognitive flexibility, the ability to adapt strategies based on feedback, is crucial for adaptive behavior.
- Disruptions in cognitive flexibility are observed in various neuropsychiatric disorders.
- Individual differences in cognitive flexibility may underlie risk and resilience in these conditions.
Purpose of the Study:
- To investigate sex-based differences in cognitive flexibility in mice.
- To identify computational mechanisms underlying these sex differences.
- To explore the relationship between sex, cognitive flexibility, and neuropsychiatric risk.
Main Methods:
- Development of a novel touchscreen Set Shift task for continuous mouse testing.
- Behavioral assessment of rule shifting performance in male and female mice.
- Application of computational models to analyze individual differences in cognitive computations.
Main Results:
- Female mice demonstrated significantly enhanced cognitive flexibility, completing more rule shifts with fewer errors than males.
- Computational models revealed sex-biased differences in learning and decision-making processes post-rule shift.
- Female mice exhibited faster rule acquisition and earlier commitment to choices, potentially by processing multiple rules concurrently.
Conclusions:
- Sex is a significant factor influencing cognitive flexibility and its underlying computations in mice.
- Enhanced choice stability in females contributes to superior cognitive flexibility in the Set Shift task.
- Findings suggest potential sex-specific mechanisms relevant to neuropsychiatric disorders.

In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will...

In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...
