Abstract
Anxiety is one of the important normally and regularly occurring emotions. Some of the actual public health problems like anxiety disorders are based on the pathology of feelings. Anxiety disorders comprise a heterogeneous group of disorders and each of these disturbances has a different etiology and outcome, and different physiological characteristics. Among the most important influences are actually genetic disposition, environmental impact upon one individual, and acute stressors that result in adaptational changes. Considering a large body of findings, several monoamine neurotransmitters and anxiogenic or anxiolytic-like neuropeptides are involved in the regulation of fear and anxiety.

Journal of EndocrinologyThe role of corticotropin-releasing factor in depression and anxiety disorders
1,380 Citations1999Lotta Arborelius, Owens Mj +2 more
The hypothesis that CRF receptor antagonists may represent a novel class of antidepressants and/or anxiolytics, probably through its effects on central noradrenergic systems, is supported.

1,273 Citations2013António R. Damásio, Gil B. Carvalho
Feelings constitute a crucial component of the mechanisms of life regulation, from simple to complex, and can be found at all levels of the nervous system, from individual neurons to subcortical nuclei and cortical regions.
Archives of General PsychiatryFalse Suffocation Alarms, Spontaneous Panics, and Related Conditions
1,137 Citations1993Donald F. Klein
The phenomena of panic during relaxation and sleep, late luteal phase dysphoric disorder, pregnancy, childbirth, pulmonary disease, separation anxiety, and treatment are used to test and illuminate the suffocation false alarm theory.
CellMolecular Mechanisms of Fear Learning and Memory
1,021 Citations2011Joshua P. Johansen, Christopher K. Cain +2 more
This work discusses the neurotransmitter systems and signaling cascades that contribute to three phases of auditory fear conditioning: acquisition, consolidation, and reconsolidation and suggests that multiple intracellular signaling pathways interact to produce neural plasticity in the LA and behavioral fear conditioning.
American Journal of PsychiatryNeuroanatomical Hypothesis of Panic Disorder, Revised
1,006 Citations2000Jack M. Gorman, Justine Kent +2 more
Medications, particularly those that influence the serotonin system, are hypothesized to desensitize the fear network from the level of the amygdala through its projects to the hypothalamus and the brainstem, and effective psychosocial treatments may also reduce contextual fear and cognitive misattributions.
Proceedings of the National Academy of SciencesFacial expressions of emotion are not culturally universal
908 Citations2012Rachael E. Jack, Oliver Garrod +3 more
By refuting the long-standing universality hypothesis, the data highlight the powerful influence of culture on shaping basic behaviors once considered biologically hardwired and open a unique nature–nurture debate across broad fields from evolutionary psychology and social neuroscience to social networking via digital avatars.
Biological PsychiatryFear and the brain: where have we been, and where are we going?
782 Citations1998Joseph E. LeDoux
The progress that has been made in understanding the neural basis of fear and its implications for anxiety disorders is surveyed, as well as the gaps in knowledge.
Biological PsychiatryCorticotropin-releasing factor, norepinephrine, and stress
627 Citations1999George F. Koob
The results suggest that endogenous CRF systems in the brain may have a role in mediating behavioral responses to stressors, and such a feed-forward mechanism in a fundamental brain-activating system may be the key to a variety of pathophysiologic conditions involving abnormal responses to Stressors.

This article shall review cellular and molecular mechanisms, as well as recent work on individual differences in anxiety-like behavior and also developmental influences that bias how the brain responds to stressors.
Journal of Anxiety DisordersState and trait anxiety revisited
573 Citations2001Norman S. Endler, Nancy L. Kocovski
It is concluded that anxiety should be viewed as a dimensional construct and that the multidimensionality of state and trait Anxiety should be considered in both theory and assessment.

Biological PsychiatryThe impact of early adverse experiences on brain systems involved in the pathophysiology of anxiety and affective disorders
496 Citations1999Christine Heim, Charles B. Nemeroff
Evidence mainly from preclinical studies suggests that stress early in life results in persistent central CRF hyperactivity and increased stress reactivity in adulthood, and this pathophysiologic model may provide novel approaches to the prevention and treatment of psychopathology associated with stressEarly in life.
Archives of General PsychiatryProspectively Ascertained Child Maltreatment and Its Association With DSM-IV Mental Disorders in Young Adults
371 Citations2010Kate M. Scott, D. R. Smith +1 more
Prospectively ascertained child maltreatment is significantly associated with a range of subsequent mood, anxiety, and substance use disorders, indicating that malt treatment, not just the memory of maltreatment, is associated with subsequent psychopathology.
Biological PsychiatryCorticotropin-releasing hormone receptor subtypes and emotion
333 Citations1999Thomas Steckler, Herta Flor
Preclinical data indicate that patients suffering from anxiety and depression may benefit from treatment with CRH1 antagonistic drugs, while drugs targeting CRH2 alpha may be of particular benefit for patients with eating disorders.

171 Citations1995Markus Heilig, E. Widerlöv
Biology, anatomy, and physiology of central NPY systems and studies of these systems in various disease states are reviewed and of particular interest is NPY's unique action as an endogenous anxiolytic and its possible role in clinical states of anxiety and depression.
