Dataset from the project investigating the presence of nonmotor symptoms of Parkinson's disease in a mouse model of progressive loss of dopaminergic neurons (namely,TIF-IADATCreERT2 strain). Mice were tested for executive and cognitive functions (males: Operant Sensation Seeking test, OSS; females: Probabilistic Reversal Learning Task in Intellicages), olfactory acuity (males: buried food test), saccharin preference (males and females), and motor performance (males and females: test using CatWalk apparatus). The dataset includes files used to perform statistical analyses but their names may vary from the ones used in the scripts. For the purpose of recreating our analyses, please refer to the GitHub page, where both scripts and input data file names are compliant: https://github.com/annaradli/tif-pd-behavior. Description of files: animals_info.csv - animals data: genotype, sex, age, Intellicage tag identifier catwalk_run_statistics_all_females.csv - data recorded in CatWalk apparatus for females catwalk_run_statistics_all_males.csv - data recorded in CatWalk apparatus for males females_weight_raw_data_revised.csv - females' body weight (revised for containing Polish words) intellicage_raw_data.csv - data recorded in IntelliCage exported to .csv format intellicage_raw_data_R.RData - data recorded in IntelliCage in .RData format males_weight_raw_data.csv - males' body weight olfactory_time_digging_raw_data.csv - time to start digging at the right place in the buried food test olfactory_time_retrieve_raw_data.csv- time to retrieve cracker in the buried food test oss_raw_data.csv - data recorded in the OSS test saccharin_preference_males_raw_data.csv - saccharin preference test results for males snvta_cells_count.csv - number of TH+ cells in SN and VTA in male mice (3+3) 14 weeks after tamoxifen treatment v2 contains the corrected 'animals_info.csv' file without an unnecessary column. v3 has a revised version of file containing females' weight measurements and also added a file with midbrain cell counts
