The neurobiology and control of anxious states
TLDR
The present article focuses in particular upon the multifarious and complex roles of individual modulators, often as a function of the specific receptor type and neuronal substrate involved in their actions; novel targets for the management of anxiety disorders; the influence of neurotransmitters and other agents upon performance in the VCT; data acquired from complementary pharmacological and genetic strategies and, finally, several open questions likely to orientate future experimental- and clinical-research.About:

The tail suspension test as a model for assessing antidepressant activity: review of pharmacological and genetic studies in mice.
TL;DR: The tail suspension test is a useful test for assessing the behavioural effects of antidepressant compounds and other pharmacological and genetic manipulations relevant to depression.
Journal ArticleDOI
Endocannabinoid-Mediated Control of Synaptic Transmission
TL;DR: This review aims to integrate the current understanding of functions of the endocannabinoid system, especially focusing on the control of synaptic transmission in the brain, and summarizes recent electrophysiological studies carried out on synapses of various brain regions and discusses how synaptic transmission is regulated by endoc cannabinoidoid signaling.
Journal ArticleDOI
Vasopressin and oxytocin release within the brain: a dynamic concept of multiple and variable modes of neuropeptide communication
Rainer Landgraf,Inga D. Neumann +1 more
TL;DR: This concept considers neuropeptides in the extracellular fluid of the brain rather than those in the cerebrospinal fluid or plasma as primary signals, triggering a variety of receptor-mediated effects, including those underlying behavioral and neuroendocrine regulation and psychopathology.
Journal ArticleDOI
Plastic Synaptic Networks of the Amygdala for the Acquisition, Expression, and Extinction of Conditioned Fear
Hans-Christian Pape,Denis Paré +1 more
TL;DR: Pavlovian fear conditioning as a model and the amygdala as a key component for the acquisition and extinction of fear responses are focused on.
Journal ArticleDOI
Ethological and temporal analyses of anxiety-like behavior: the elevated plus-maze model 20 years on.
TL;DR: In this paper, the authors present a review of the use of the EPM as a post-hoc test to evaluate emotionality in genetically modified rodents and identify and control of major sources of variability in this test.

Emotion Circuits in the Brain
TL;DR: The field of neuroscience has, after a long period of looking the other way, again embraced emotion as an important research area, and much of the progress has come from studies of fear, and especially fear conditioning as mentioned in this paper.
Journal ArticleDOI
How do glucocorticoids influence stress responses? Integrating permissive, suppressive, stimulatory, and preparative actions.
TL;DR: This review considers recent findings regarding GC action and generates criteria for determining whether a particular GC action permits, stimulates, or suppresses an ongoing stress-response or, as an additional category, is preparative for a subsequent stressor.

The Structure of the Potassium Channel: Molecular Basis of K+ Conduction and Selectivity
Declan A. Doyle,João H.Morais Cabral,Richard A. Pfuetzner,Anling Kuo,Jacqueline M. Gulbis,Steven L. Cohen,Brian T. Chait,Roderick MacKinnon +7 more
TL;DR: The architecture of the pore establishes the physical principles underlying selective K+ conduction, which promotes ion conduction by exploiting electrostatic repulsive forces to overcome attractive forces between K+ ions and the selectivity filter.

Association of Anxiety-Related Traits with a Polymorphism in the Serotonin Transporter Gene Regulatory Region
Klaus-Peter Lesch,D. Bengel,Armin Heils,Sue Z. Sabol,Benjamin D. Greenberg,Susanne Petri,Jonathan Benjamin,Clemens R. Müller,Dean H. Hamer,Dennis L. Murphy +9 more
TL;DR: The short variant of the polymorphism reduces the transcriptional efficiency of the 5-HTT gene promoter, resulting in decreased 5HTT expression and 5HT uptake in lymphoblasts as discussed by the authors, which is the site of action of widely used uptake-inhibiting antidepressant and antianxiety drugs.

Précis of The Neuropsychology of Anxiety: An Enquiry into the Functions of the Septo-Hippocampal System..
TL;DR: It is proposed that these drugs reduce anxiety by impairing the functioning of a widespread neural system including the septo-hippocampal system (SHS), the Papez circuit, the prefrontal cortex, and ascending monoaminergic and cholinergic pathways which innervate these forebrain structures.
