Environmental Novelty Differentially Affects c-fosmRNA Expression Induced by Amphetamine or Cocaine in Subregions of the Bed Nucleus of the Stria Terminalis and Amygdala

The data suggest that the context in which psychostimulants are given powerfully and differentially alters the response of limbic structures that have been functionally implicated in drug reinforcement and emotional behaviors.

Hypothalamic Arousal Regions Are Activated during Modafinil-Induced Wakefulness

Modafinil may promote waking via activation of TMN and orexin neurons, two regions implicated in the promotion of normal wakefulness, and Selective pharmacological activation of these hypothalamic regions may represent a novel approach to inducing wakefulness.

Effect of the wake-promoting agent modafinil on sleep-promoting neurons from the ventrolateral preoptic nucleus: an in vitro pharmacologic study.

Results suggest that modafinil blocks the reuptake of Noradrenaline by the noradrenergic terminals on sleep-promoting neurons from the VLPO, suggesting that such a mechanism could be at least partially responsible for the wake-promoted effect of modafInil.

Amphetamine-Induced Fos is Reduced in Limbic Cortical Regions but not in the Caudate or Accumbens in a Genetic Model of NMDA Receptor Hypofunction

A neuroanatomically selective activation deficit to amphetamine challenge in the NR1-deficient mice is suggested, which may have relevance to the hypothesized NMDA receptor hypofunction in schizophrenia.

Immediate-early gene expression in the central nucleus of the amygdala is not specific for anxiolytic or anxiogenic drugs

Functional internal complexity of amygdala: focus on gene activity mapping after behavioral training and drugs of abuse.

The studies on the gene activity markers, confronted with other approaches involving neuroanatomy, physiology, and the lesion method, have revealed novel aspects of the amygdala, especially pointing to functional heterogeneity of this brain region that does not fit very well into contemporarily active debate on serial versus parallel information processing within the amygdala.

Evidence is provided for the potential brain targets of modafinil, which differ from those of amphetamine or methylphenidate, and suggest that modaf inil induces wakefulness by mechanisms distinct from Those of the two stimulants.

Amphetamine and cocaine induce drug-specific activation of the c-fos gene in striosome-matrix compartments and limbic subdivisions of the striatum.

It is proposed that differential activation of immediate-early genes by psychostimulants may be an early step in drug-specific molecular cascades contributing to acute and long-lasting psychostIMulant-induced changes in behavior.

An important role is demonstrated for the amygdala in the control of behavioral state and alerting mechanisms and it is suggested that 5-HT exerts some of its regulatory effects via an influence on forebrain regions.
