Huntington’s Disease is a neurodegenerative genetic disorder caused by CAG repeat expansion in the huntingtin gene that generates motor, cognitive and psyquiatric symptoms in humans. In this work, our objective was to evaluate sex differences in cognitive and motor function of zQ175 knock-in (HD) and wild type (WT) mice at 4 or 8 months (M) of age. We tested their behavior by using the open field test, the gait analysis, and the novel object recognition (NOR)test.Results: In the open field test, HD female mice traveled less distance, moved more slowly(p
