Utilizing a rat model of fetal alcohol spectrum disorder (FASD), ethanol was administered over postnatal days (PD) 4 to 9. As adults, control and ethanol rats underwent trace fear conditioning (TFC), in which a tone conditioned stimulus (CS) and footshock unconditioned stimulus (US) were repeatedly paired, though the two stimuli never overlapped in time.(More)
Dopamine modulates cognitive functions through regulation of synaptic transmission and plasticity in the hippocampus and prefrontal cortex (PFC). Thus, dopamine dysfunction in depression may be particularly relevant for the cognitive symptoms. The norepinephrine transporter inhibitor reboxetine facilitates memory processing in both healthy volunteers and in(More)
BACKGROUND Histamine is a modulatory neurotransmitter regulating neuronal activity. Antidepressant drugs target modulatory neurotransmitters, thus ultimately regulating glutamatergic transmission and plasticity. Histamine H3 receptor (H3R) antagonists have both pro-cognitive and antidepressant effects; however, the mechanism by which they modulate glutamate(More)
Growing evidence links adverse prenatal conditions to mood disorders. We investigated the long-term behavioral alterations induced by prenatal exposure to excess glucocorticoids (dexamethasone--DEX). At 12 months, but not earlier, DEX-exposed mice displayed depression-like behavior and impaired hippocampal neurogenesis, not reversible by the antidepressant(More)
BACKGROUND The psychotomimetic phencyclidine (PCP) produces behavioral symptoms similar to those observed in schizophrenia, accompanied by increased motor activity. The dopamine and adenosine 3',5'-cyclic monophosphate-regulated phosphoprotein of 32kDa (DARPP-32) is enriched in the medium spiny neurons (MSNs) of the striatum and has been implicated in the(More)
