phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• 2-3 month-old mice have shorter time to right than wild-type
• with age, righting time increases significantly compared to young transgenic mice; controls do not show significant differences with age
• with age (at 7-9 and 16-18 months), mice have undergone a progressive decline in locomotor activity
• 2-3 month-old mice are more active relative to wild-type

nervous system
• neurons in median forebrain bundle are more beaded and dilated in appearance compared to controls in young (2-3 months) mice
• terminals of neurons in the nucleus accumbens are abnormal with small caliber processes and dilated or enlarged terminals

homeostasis/metabolism
• dopamine levels are lower in transgenic brains than in control brains; in aged mice, levels are signicantly lower than in 2-3 month-old transgenic mice
• similar results are seen for dopamine metabolites like DOPAC and homovanillic acid

N normal phenotype
behavior/neurological
• locomotor activity is only 60% of littermate controls by 21-23 months of age
• treatment with a high dose of apomorphine increases locomotor activity to 171% of their habituation control levels
• mice exposed to progressive treatments of combined pesticides show a persistent reduction of about 70% in locomotor activity

homeostasis/metabolism
• mice exposed to combined pesticides exhibit a 56% decrease in the level of dopamine and decreased trends for its metabolites
• dopamine turnover is elevated by 50% in mice exposed to combined pesticides
• mice exposed to progressive treatments of combined pesticides show a persistent reduction of about 70% in locomotor activity
• mice treated with combined pesticides show a greater loss of dopaminergic (TH+) neurons than control littermates
• mice exposed to combined pesticides exhibit a 56% decrease in the level of dopamine and decreased trends for its metabolites, a 40% reduction in dihydroxyphenylacetic acid (DOPAC) levels, a 20% non-statistically significant decrease in homovanillic acid, and a 50% elevation in dopamine turnover
• however, no changes in 5HT levels in the striatum are seen in mice exposed to combined pesticides

nervous system
• mice show a significant loss of TH+ neurons across time in the substantia nigra pars compacta, with an approximate 19% loss at 8.5 months and approximate 55% loss at 19 months of age
• however, inclusions are not seen in the substantia nigra pars compacta
• mice treated with combined pesticides show a greater loss of dopaminergic (TH+) neurons than control littermates
