2004, Brain ResearchCitation Excerpt :It coud be, as suggested by Tanaka et al. [40], that such a frontal dysfunction is characterized by an impairment of the inhibitory system. Such a view would agree with decrease in anxiety, neophilic reactions and disinhibition recorded in mutant mice whose cerebellar cortex is almost completely degenerated, such as staggerer [15], in early cerebellar lesioned rats [3], as well as in transgenic mice overexpressing bcl-2 in neurons [33] which are characterized by supernumerary neurons in the central nervous system, including the cerebellum. We have previously found a functional lateralization of the cerebellum concerning motor function, the motor deficits being more pronounced after left as opposed to right cerebellar damage [7].
Cytochrome oxidase activity in the olfactory system of staggerer mutant mice
2001, Brain ResearchCitation Excerpt :The same phenotype is observed after targeted deletion of the RORα gene, indicating that the staggerer mutation is caused by a loss of function of this gene [41]. In addition to the motor deficits, olfactory discrimination [5] and olfactory learning [6] are impaired, together with changes in the exploration of environmental stimuli [13,22] and in social interactions [1,2]. The deficient olfactory and social behaviors are likely to be caused by RORα deletion in the olfactory bulb, normally expressed during postnatal development and the adult period [36,41].
