Abstract
Neonatal basolateral amygdala (nBLA) lesions in rats have been widely used as a neurodevelopmental model that mimics schizophrenia-like behaviors. Recently, we reported that nBLA lesions result in significant decreases in the dendritic spine number of layer 3 prefrontal cortex (PFC) pyramidal cells and medium spiny neurons of the nucleus accumbens (NAcc), which all changes after puberty. At present, we aimed to evaluate the effect of this lesion in pyramidal neurons of CA1 of the ventral hippocampus (VH) and layer 5 of the PFC. In order to assess the effects of nBLA lesions on the dendritic morphology of the PFC and VH neurons, we carried out nBLA lesions in rats on postnatal day (PD) 7, and then we studied the dendritic morphology of these two limbic subregions at prepubertal (PD35) and postpubertal (PD60) ages. Dendritic characteristics were measured by Golgi-Cox procedure followed by Sholl analysis. We also evaluated the effects of nBLA lesions on the prepulse inhibition (PPI) and acoustic startle responses. The nBLA lesion induced a significant increase in dendritic length of layer 5 pyramidal neurons of the PFC at both ages, with a decrease in the dendritic spines density after puberty. The spine density of CA1 VH pyramidal neurons showed significant decreases at both ages. PPI was decreased in adulthood in the animals with an nBLA lesion. These results show that an nBLA lesion alters the dendritic morphology at the level of the PFC and VH in distinct ways before puberty, suggesting a disconnection between these limbic structures at an early age, and increasing our understanding of the implications of the VH in early amygdala dysfunction in schizophrenia.

Abstract
Tonic immobility (TI) is also known as "immobility response", "immobility reflex", "animal hypnosis", etc. It is an innate antipredatory behavior characterized by an absence of movement, varying degrees of muscular activity, and a relative unresponsiveness to external stimuli. Experimentally, TI is commonly produced by manually forcing an animal into an inverted position and restraining it in that position until the animal becomes immobile. Part of the neural mechanism(s) of TI involves the medullo-pontine reticular formation, with influence from other components of the brain, notably the limbic system. It has been observed that TI is more prolonged in stressed animals, and systemic injection of corticosterone (CORT) also potentiates this behavior. At present, the anatomical brain regions involved in the CORT modulation of TI are unknown. Thus, our study was made to determine if some pontine areas could be targets for the modulation of TI by CORT. A unilateral nucleus pontis oralis (PnO) microinjection of 1 μL of CORT (0.05 μg/1 μL) in rats resulted in clear behavioral responses. The animals had an increased duration of TI caused by clamping the neck (in this induction, besides of body inversion and restraint, there is also clamping the neck), with an enhancement in open-field motor activity, which were prevented by pretreatment injection into PnO with 1 μL of the mineralocorticoid-receptor antagonist spironolactone (0.5 μg/1 μL) or 1 μL of the glucocorticoid-receptor antagonist mifepristone (0.5 μg/1 μL). In contrast, these behavioral changes were not seen when CORT (0.05 μg/1 μL) was microinjected into medial lemniscus area or paramedian raphe. Our data support the idea that, in stressful situations, glucocorticoids released from adrenals of the prey reach the PnO to produce a hyper arousal state, which in turn can prolong the duration of TI.

Abstract
Clamping the neck followed by body inversion to a supine position in mice elicits an immobility response called immobility by clamping the neck (ICN). The noxious pinch to the scruff of the neck produces antinociception in "phasic pain" models (e.g. tail-flick test). Here, a "tonic pain" model was used to test the antinociception associated with the ICN, and naloxone was used to determine the role of opioids in such antinociception. Mice were injected intraperitoneally with 0.3 mL of 0.4% acetic acid to produce writhing responses that were measured for one hour. ICN was induced every five minutes for one hour. Naloxone (5 mg/kg ip) was injected 10 min before acetic acid administration. There was a control group, sham clamping (SCLA). These mice were handled and restricted every five minutes as in the ICN but without real clamping. The repetitive inductions of ICN were able to reduce the writhing behavior; this antinociception was blocked by the naloxone pretreatment. In the SCLA group antinociception was not observed. These findings indicate that as in the "phasic pain" model, ICN also was able to elicit antinociception in this "tonic pain" model, and such antinociception seems to be mediated by opioids.

Abstract
Transient global anoxia after Cesarean birth in rats may produce alterations in the subcortical DA function and related behaviors. The reports only tested the behavioral changes induced by a general DA agonist, such as amphetamine or apomorphine, in adult rats. Here we investigated the role of perinatal anoxia on the locomotion induced by a specific dopamine (DA) agonist and its relation to the DA D1-like and D2-like receptors, measured by autoradiography at two different ages, prepubertal (35 days old, P35) and postpubertal (60 days old, P60). Cesarean birth with or without (C-only) an additional period of 10 min of the anoxia was done in Sprague-Dawley rats, and the effects of the DA D1-like and D2-like agonist and their receptors were studied at P35 and P60. In addition, a third group of animals born vaginally served as the control. The quantitative autoradiography study of the DA D1-like and D2-like receptors revealed an enhancement of the DA D1-like receptor levels in the nucleus accumbens (NAcc) and dorsolateral part of the caudate-putamen in the prepubertal C-only animals. The postpubertal C-only rats showed a decrease in the levels of DA D2-like receptors in the NAcc. However, quinpirole, a DA D2 agonist (0.125 and 0.25 mg/kg, s.c.), induced a dose-dependent increase of the locomotor activity in the animals born by Cesarean with anoxia at birth at both ages. Our results suggest that Cesarean with or without anoxia at birth may mediate differently the neurodevelopmental aspects of the dopaminergic system before and after puberty.

Abstract
Here we have investigated whether differences in levels of dopamine D1-like, D2-like receptors, dopamine D3 receptors, and dopamine transporter could be related to behaviors such as immobility response and locomotion between Wistar rats and Sprague-Dawley rats. The levels of the dopamine receptors and transporter were measured by autoradiographic study at the level of basal ganglia and the limbic subregion. The behavioral study was done by open-field and immobility response tests. The Wistar rats exhibited a higher level of D1 receptor binding in the basal ganglia subregions than Sprague-Dawley rats. The Wistar rats have higher levels of dopamine D2 receptor binding and dopamine transporter binding in the dorsolateral part of the caudate-putamen. In addition, the dopamine transporter binding were also higher in the Wistar rats than in Sprague-Dawley rats in the ventral part of the caudate-putamen and nucleus accumbens core. However, there were no differences in the level of D3 receptor binding in the limbic or basal ganglia subregions between these two strains. In Wistar rats, the duration of the immobility responses was longer and with less locomotor activity after these immobility responses compared with Sprague-Dawley rats. These data suggest that the differences in dopamine receptors in these two rat strains may in part relate to the behavioral differences reported in these two strains.
