Design of a neurally plausible model of fear learning.

Frontiers in behavioral neuroscience

Krasne FB, Fanselow MS, Zelikowsky M.
PMID: 21845175
Front Behav Neurosci. 2011 Jul 26;5:41. doi: 10.3389/fnbeh.2011.00041. eCollection 2011.

A neurally oriented conceptual and computational model of fear conditioning manifested by freezing behavior (FRAT), which accounts for many aspects of delay and context conditioning, has been constructed. Conditioning and extinction are the result of neuromodulation-controlled LTP at synapses...

Reinstatement of extinguished fear by an unextinguished conditional stimulus.

Frontiers in behavioral neuroscience

Halladay LR, Zelikowsky M, Blair HT, Fanselow MS.
PMID: 22586379
Front Behav Neurosci. 2012 May 04;6:18. doi: 10.3389/fnbeh.2012.00018. eCollection 2012.

Anxiety disorders are often treated using extinction-based exposure therapy, but relapse is common and can occur as a result of reinstatement, whereby an aversive "trigger" can reinstate extinguished fear. Animal models of reinstatement commonly utilize a Pavlovian fear conditioning...

The Role of Learning in Threat Imminence and Defensive Behaviors.

Current opinion in behavioral sciences

Fanselow MS.
PMID: 30276224
Curr Opin Behav Sci. 2018 Dec;24:44-49. doi: 10.1016/j.cobeha.2018.03.003. Epub 2018 Mar 20.

Life threatening situations as urgent as defending against a predator precludes the use of slow trial and error strategies. Natural selection has led to the evolution of a behavioral system that has 3 critical elements. 1) When it is...

The Danger of LeDoux and Pine's Two-System Framework for Fear.

The American journal of psychiatry

Pavlovian occasion setting in human fear and appetitive conditioning: Effects of trait anxiety and trait depression.

Behaviour research and therapy

Zbozinek TD, Wise T, Perez OD, Qi S, Fanselow MS, Mobbs D.
PMID: 34740100
Behav Res Ther. 2021 Dec;147:103986. doi: 10.1016/j.brat.2021.103986. Epub 2021 Oct 09.

Contexts and discrete stimuli often hierarchically influence the association between a stimulus and outcome. This phenomenon, called occasion setting, is central to modulation-based Pavlovian learning. We conducted two experiments with humans in fear and appetitive conditioning paradigms, training stimuli...

The nature and nurture of education.

NPJ science of learning

Sah P, Fanselow M, Quirk GJ, Hattie J, Mattingley J, Tokuhama-Espinosa T.

Postnatal maturation of somatostatin-expressing inhibitory cells in the somatosensory cortex of GIN mice.

Frontiers in neural circuits

Kinnischtzke AK, Sewall AM, Berkepile JM, Fanselow EE.
PMID: 22666189
Front Neural Circuits. 2012 May 31;6:33. doi: 10.3389/fncir.2012.00033. eCollection 2012.

Postnatal inhibitory neuron development affects mammalian brain function, and failure of this maturation process may underlie pathological conditions such as epilepsy, schizophrenia, and depression. Furthermore, understanding how physiological properties of inhibitory neurons change throughout development is critical to understanding...

The effect of stress and reward on encoding future fear memories.

Behavioural brain research

DiFazio LE, Fanselow M, Sharpe MJ.
PMID: 34543677
Behav Brain Res. 2022 Jan 24;417:113587. doi: 10.1016/j.bbr.2021.113587. Epub 2021 Sep 17.

Prior experience changes the way we learn about our environment. Stress predisposes individuals to developing psychological disorders, just as positive experiences protect from this eventuality (Kirkpatrick & Heller, 2014; Koenigs & Grafman, 2009; Pechtel & Pizzagalli, 2011). Yet current...

The role of the ventromedial prefrontal cortex and context in regulating fear learning and extinction.

Psychology & neuroscience

Gonzalez ST, Fanselow MS.
PMID: 34504659
Psychol Neurosci. 2020 Sep;13(3):459-472. doi: 10.1037/pne0000207. Epub 2020 Apr 16.

An organism's ability to learn about and respond to stimuli in its environment is crucial for survival, which can involve learning simple associations such as learning what stimuli predict danger. However, individuals must also be able to use contextual...

Alpha-synuclein pathology, microgliosis, and parvalbumin neuron loss in the amygdala associated with enhanced fear in the Thy1-aSyn model of Parkinson's disease.

Neurobiology of disease

Torres ERS, Stanojlovic M, Zelikowsky M, Bonsberger J, Hean S, Mulligan C, Baldauf L, Fleming S, Masliah E, Chesselet MF, Fanselow MS, Richter F.
PMID: 34390837
Neurobiol Dis. 2021 Oct;158:105478. doi: 10.1016/j.nbd.2021.105478. Epub 2021 Aug 11.

In Parkinson's disease (PD), the second most common neurodegenerative disorder, non-motor symptoms often precede the development of debilitating motor symptoms and present a severe impact on the quality of life. Lewy bodies containing misfolded α-synuclein progressively develop in neurons...

Recent work has demonstrated that social support figures seem to be particularly robust inhibitors of the Pavlovian fear response. Specifically, social support figures appear to act as
