The corticotropin-releasing hormone receptor 1 (CRHR1) critically controls behavioral adaptation to stress and is causally linked to emotional disorders. Using neurochemical and genetic tools, we determined that CRHR1 is expressed in forebrain glutamatergic and γ-aminobutyric acid-containing (GABAergic) neurons as well as in midbrain dopaminergic neurons.(More)
We have analyzed the appearance of N-acetylgalactosamine containing glycoconjugates by staining sections of fixed cat visual cortex with the lectins from Vicia villosa (VVA) and Glycine max (SBA) conjugated to fluorescent labels, horseradish peroxidase, or biotin. The appearance of lectin staining during postnatal development followed an inside-out gradient(More)
We investigated whether voluntary exercise and concurrent antidepressant treatment (tianeptine; 20 mg/kg/day; 4 weeks) exert synergistic effects on the mouse hypothalamic-pituitary-adrenocortical (HPA) axis. Animals had access to a running wheel, were treated with the antidepressant, or received both conditions combined. Control mice received no running(More)
We consider an investor maximizing his expected utility from terminal wealth with portfolio decisions based on the available information flow. This investor faces the opportunity to acquire some additional initial information G. His subjective fair value of this information is defined as the amount of money that he can pay for G such that this cost is(More)
BACKGROUND In a substantial proportion of depressed patients, stressful life events play a role in triggering the evolution of the illness. Exposure to stress has effects on different levels in laboratory animals as well and for the rat it has been shown that chronic mild stress (CMS) can cause antidepressant-reversible depressive-like effects. The adoption(More)
The present investigation uses an in vitro co-culture system to study the role of afferent innervation in early development and differentiation of hippocampal neurons. Our experiments indicate that the formation of two key morphological features, dendritic branches and dendritic spines, is induced by afferent innervation. Hippocampal neurons develop(More)
The study investigated the formation of perforated synapses in rat hippocampal cell cultures. Perforated synapses are defined by their discontinuous postsynaptic densities (PSDs) and are believed to occur in parallel with changes in synaptic activity and possibly also synaptic efficacy. Several in vivo studies have demonstrated an increase in the frequency(More)
