Abstract
Bergamot (Citrus bergamia, Risso) is a fruit most knowledgeable for its essential oil (BEO) used in aromatherapy to minimize symptoms of stress-induced anxiety and mild mood disorders and cancer pain though the rational basis for such applications awaits to be discovered. The behavioural and EEG spe...

Abstract
Operant self-administration procedures are used to assess the neural basis of ethanol-seeking behavior under a wide range of experimental conditions. In general, rats do not spontaneously self-administer ethanol in pharmacologically meaningful amounts. This unit provides a step-by-step guide for tra...

Abstract
We asked what combination of potencies in these three modes of TRPV1 activation corresponds to the lowest potency of a TRPV1 antagonist to cause hyperthermia. We studied hyperthermic responses of rats, mice, and guinea pigs to eight TRPV1 antagonists with different pharmacological profiles and used...

Abstract
We have applied these techniques to investigate the anti-tumor effect of NSAIDs, isolate novel genes specifically expressed in rheumatoid arthritis, and analyze gene expression profiles in mesenchymal stem cells. Recently, we have developed a novel system of quantitative PCR for detection of BDNF mR...

Abstract
We examined the effects of acute and repeated dosing with two antipsychotics, haloperidol and clozapine, and Delta(9)-tetrahydrocannabinol [Experiments 1 and 2, respectively] in adolescent rats of both sexes that differed in shipping status (i.e., shipped from a commercial breeder at weaning or bred...

Abstract
I noted 5 years ago, 'Unless steps are taken soon to undertake a comprehensive restoration of our system, the profound advances in bio-medical research so rapidly accruing today may never be effectively transformed into meaningful advances in health care for society.' I remain perplexed and frustrat...

Abstract
Two naturally occurring tropane alkaloids, anisodamine and scopolamine, structurally dissimilar in one OH group, are well established as muscarinic acetylcholine receptor (mAChR) antagonists in clinic and basic research. However, experimental evidence for central effects of anisodamine is limited an...

Abstract
We compared the effects of mode of delivery of neuroactive agents and the effects of dimethyl sulfoxide (DMSO), a vehicle for dissolving neuroactive agents, on locomotor-like activity in vitro. By superfusion, d-glutamate (0.3-0.9 mM) produced robust walking-like activity at superfusion rates 10-25...

Abstract
The vasoconstrictor substance named serotonin was identified as 5-hydroxytryptamine (5-HT) by Maurice Rapport in 1949. In 1951, Rapport gave Gaddum samples of 5-HT substance allowing him to develop a bioassay to both detect and measure the amine. Gaddum and colleagues rapidly identified 5-HT in brai...

Abstract
The aim of the study was to evaluate the use of imaging in the development of neuropharmacological drugs. All New Drug Applications (NDAs) approved from 1995 through 2004 in the Division of Neuropharmacological Drug Products at the Food and Drug Administration were surveyed for imaging studies. Imag...

Abstract
It seems that the well investigated khat alkaloids have many features similar to amphetamines; however there is a need for a more thorough examination of khat itself in well designed in vitro, animal and human studies with a range of comparator drugs before confirming the claim that khat is a "natur...

Abstract
The advent of multiple new antiepileptic drugs (AEDs) in the past 15 years has provided new options for clinicians treating patients with epilepsy, but has also created a need for guidelines in AED use. For selection of the most appropriate AED, the neurologist must know the pharmacological properti...

We present here the concept of a virtual archive, spatially referenced over a simplified 3D brain map and accessible over the Internet. A simple prototype (available at http://aquatics.crs4.it/neuropsydat3d) has been realized using current Web-based virtual reality standards and technologies. It ill...

Abstract
We report the pharmacological and neurochemical characterization of two novel and selective 5-HT6 receptor agonists. WAY-181187 and WAY-208466 possess high affinity binding (2.2 and 4.8 nM, respectively) at the human 5-HT6 receptor and profile as full receptor agonists (WAY-181187: EC50=6.6 nM, Emax...

Abstract
Thirty years of clinical investigation of patients with prion disease has resulted in little progress in either defining or evaluating potential treatments. Disease course and treatment of all patients must be evaluated within a structured framework, preferably within randomized controlled trials....

Abstract
Ten new antiepileptic drugs have been developed in the last two decades, making selection of optimal therapy complex; they have not been shown to have better efficacy but generally seem to be better tolerated. Newer antiepileptic drugs offer new opportunities to patients who have not had a favorable...

Abstract
Personalized medicine is still in its infancy concerning drug development in neuropsychopharmacology. Adequate biomarkers with clinical relevance to drug response and/or tolerability and safety largely remain to be identified. Possibly, this kind of personalized medicine will first gain clinical rel...

Abstract
This article assesses pain within the context of the dose response. A substantial number of studies indicate that the dose response for pain-related endpoints is commonly biphasic, being independent of the type of biological model employed, endpoint measured, or agent tested. The quantitative feature...

Abstract
We survey Dr. Calabrese's findings, illustrate the somewhat provocative premise of hormesis, and posit that while evidence suggests that amplification of low-dose effects are operative in neural systems, it is equally important to consider observations and claims of hormesis in greater detail, and f...

Abstract
Hormesis is defined operationally as responses of cells or organisms to an exogenous or intrinsic factor (chemical, temperature, psychological challenge, etc.) in which the factor induces stimulatory or beneficial effects at low doses and inhibitory or adverse effects at high doses. The compendium of...

Abstract
A beam-walking apparatus has been evaluated for its ability to detect motor impairments in mice acutely treated with the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg, s.c., single or double administration). Mice subjected to MPTP lesioning showed deficits in m...

Abstract
An unavoidable consequence of enzymatic dispersion of sensory neurons from intact ganglia is loss of the axon and thus the ability to classify afferent fiber type based upon conduction velocity (CV). An intact rat nodose ganglion preparation was used to randomly sample neurons (n=76) using the patch...
