Dosage Compensation

Dosage Compensation

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...

The Ratio of X Chromosome to Autosomes

The Ratio of X Chromosome to Autosomes

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...

Neuroscience
Behavioral Science
Computational Psychiatry

Background:

Cognitive flexibility, the ability to adapt strategies based on feedback, is impaired in neuropsychiatric disorders.
Individual differences in cognitive flexibility offer insights into neuropsychiatric risk and resilience.
Sex is a known factor influencing neuropsychiatric risk, but its role in cognitive flexibility is unclear.

Purpose of the Study:

To investigate sex-based differences in cognitive flexibility using a novel touchscreen Set Shift task in mice.
To identify computational mechanisms underlying sex-biased performance in cognitive flexibility.

Main Methods:

Development of a novel touchscreen Set Shift task for continuous mouse testing.
Assessment of sex differences in rule shifting accuracy and errors.
Application of computational models to analyze individual differences in cognitive computations.

Main Results:

Female mice significantly outperformed males, completing more rule shifts with fewer errors.
Computational models revealed sex-specific differences in learning and decision-making computations.
Females demonstrated faster rule acquisition and earlier commitment to choices post-shift, sometimes exploring multiple rules concurrently.

Conclusions:

Sex is a significant factor influencing cognitive flexibility in mice.
Enhanced choice stability in females contributes to superior cognitive flexibility.
These findings suggest stable choice is essential for effective strategy shifting in a key cognitive task.
