Frequent expression of stereotypies by pigs has been reported, even when pigs are not maintained in crates. This behavior is only observed in animals kept in captivity and is a wide-range welfare indicator, since it is considered to deve

2. Behavioral effects of endogenous or exogenous estradiol and progesterone on cocaine sensitization in female rats
Cocaine sensitization is a marker for some facets of addiction, is greater in female rats, and may be influenced by their sex hormones. We compared the modulatory effects of endogenous or exogenous estradiol and progesterone on cocaine-induced behavioral sensitization in 106 female rats. Ovariectomized female rats received progesterone (0.5 mg/mL), estradiol

4. Comparação e descrição de parâmetros acústicos do canto de Volatinia jacarina (Aves: Emberizidae) no contexto de seleção sexual
Bird songs may convey information about the quality of the male, and females can access this information during partner choice. The aim of this study was to test for correlations between acoustic parameters of songs from Volatinia jacarina males and their physical attributes. First we determined, through quantitative analysis, the degree of stereotypy in the

8. A produção de variabilidade da dimensão duração da resposta de focinhar: uma replicarão de Cruvinel (2002) / Proimoting variability of nose-poking response duration in rats: A replication of Cruvinel (2002)
A variabilidade é uma propriedade importante do comportamento. Estudos na análise do comportamento têm investigado se a variabilidade pode ser produto de reforço contingente à variação. O presente estudo pretendeu fazer uma replicação do trabalho de Cruvinel (2002), o qual estudou a variabilidade como produto de reforçamento contingente utilizando

10. Dopaminergic profile of new heterocyclic N-phenylpiperazine derivatives
Dopamine constitutes about 80% of the content of central catecholamines and has a crucial role in the etiology of several neuropsychiatric disorders, including Parkinson's disease, depression and schizophrenia. Several dopaminergic drugs are used to treat these pathologies, but many problems are attributed to these therapies. Within this context, the search

11. Induction of stereotypy in dopamine-deficient mice requires striatal D1 receptor activation
Motor stereotypies are abnormally repetitive behaviors that can develop with excessive dopaminergic stimulation and are features of some neurologic disorders. To investigate the mechanisms required for the induction of stereotypy, we examined the responses of dopamine-deficient (DD) mice to increasing doses of the dopamine precursor l-DOPA. DD mice lack the

12. On The Role of Preference in Response Competition
A duration-based preference assessment identified items that matched and did not match the sensory consequences hypothesized to maintain stereotypy. When evaluated in treatment, these items effectively competed with the occurrence of stereotypy, regardless of their sensory properties. It is suggested that relative preference, as measured in duration-based as
