Delayed effects of chronic variable stress during peripubertal‐juvenile period on hippocampal morphology and on cognitive and stress axis functions in rats
Animal studies on the effects of chronic variable stress during the peripubertal‐juvenile period on hippocampal structure and function are lacking. Twenty‐eight‐day‐old Sprague‐Dawley rats wereExpand

Prenatal Gonadal Steroids Affect Adult Spatial Behavior, CA1 and CA3 Pyramidal Cell Morphology in Rats
The present study assessed whether prenatal androgen and estrogen exposure affected adult spatial learning and hippocampal morphology. Water maze performance, the CA1 and CA3 pyramidal cell field,Expand

Stress during adolescence alters behavioral sensitization to amphetamine
In humans, chronic intermittent and uncontrollable stress during adolescence is viewed as a key factor for vulnerability to drug abuse and development of psychopathologies later in life. Less isExpand

Effects of neonatal gonadal steroids on adult CA3 pyramidal neuron dendritic morphology and spatial memory in rats.
The hippocampus is implicated in spatial cognition, which is sexually dimorphic and developmentally sensitive to gonadal steroids. Previously we have shown a sex difference in CA3 pyramidal cellExpand

Estrogen receptor β in the paraventricular nucleus of hypothalamus regulates the neuroendocrine response to stress and is regulated by corticosterone
The function of the second nuclear estrogen receptor, estrogen receptor beta (ERbeta), in the brain is largely unknown. The present study tested whether 1) ERbeta in the paraventricular nucleus (PVN)Expand

Colocalization of estrogen β-receptor messenger RNA with orphanin FQ, vasopressin and oxytocin in the rat hypothalamic paraventricular and supraoptic nuclei
The functional significance of the novel estrogen receptor β in brain areas that exclusively contain the ERβ receptor subtype such as the paraventricular (PVN) and the supraoptic (SON) nuclei of theExpand

Hippocampus modulates the behaviorally‐sensitizing effects of nicotine in a rat model of novelty‐seeking: Potential role for mossy fibers
Present experiments investigate interactions between a rat model of the novelty‐seeking phenotype and psychomotor sensitization to nicotine (NIC) in adolescence, and the potential role of hippocampalExpand

Nicotine-induced anxiety-like behavior in a rat model of the novelty-seeking phenotype is associated with long-lasting neuropeptidergic and neuroplastic adaptations in the amygdala: Effects of the
A rat model of the novelty-seeking phenotype predicts vulnerability to the expression of behavioral sensitization to nicotine, where locomotor reactivity to novelty is used to screenExpand

Response of olfactory axons to loss of synaptic targets in the adult mouse
Glomerular convergence has been proposed to rely on interactions between like olfactory axons, however topographic targeting is influenced by guidance molecules encountered in the olfactory bulb.Expand

The δ-Opioid Receptor Agonist (+)BW373U86 Regulates BDNF mRNA Expression in Rats
δ-Opioid receptor agonists have antidepressant-like effects in behavioral models of depression. Chronic administration of classical antidepressants upregulates mRNA expression of brain-derivedExpand
