Cholinergic Signaling Alters Stress-Induced Sensitization of Hippocampal Contextual Learning
Post-traumatic stress disorder (PTSD) has a profound contextual component, and has been demonstrated to alter future contextual learning. However, the mechanism by which a single traumatic event affects subsequent contextual experiences has not been ...

Many contemporary studies of human fear conditioning exclude participants who fail to show differential electrodermal responding during late stages of acquisition training, deeming them to be non-Learners. The current study examined whether non-Learners,

Pre-Learning Stress That Is Temporally Removed from Acquisition Impairs Fear Learning
Few studies have examined the time-dependent effects of stress on fear learning. Previously, we found that stress immediately before fear conditioning enhanced fear learning.

Rapid synaptic potentiation within the anterior cingulate cortex mediates trace fear learning
Although the cortex has been extensively studied in long-term memory storage, less emphasis has been placed on immediate cortical contributions to fear memory formation.

Enhanced Instructed Fear Learning in Delusion-Proneness
Psychosis is associated with distorted perceptions and deficient bottom-up learning such as classical fear conditioning. This has been interpreted as reflecting imprecise priors in low-level predictive coding systems. Paradoxically, overly strong beliefs,

Estimating students' online learning satisfaction during COVID-19: A discriminant analysis
This study aims to examine online learning effects regarding self-efficacy, generalized anxiety, and fear of COVID-19 on three distinct online learning satisfaction levels (low, moderate, and high) among university students.

ABL1 in thalamus is associated with safety but not fear learning
In auditory fear conditioning a tone is paired with a footshock, establishing long lasting fear memory to the tone. In safety learning these stimuli are presented in an unpaired non-overlapping manner and enduring memories to the tone as a safety signal ...

Learning not to Fear: Neural Correlates of Learned Safety [PDF]
The ability to recognize and properly respond to instances of protection from impending danger is critical for preventing chronic stress and anxiety-central symptoms of anxiety and affective disorders afflicting large populations of people. Learned safety encompasses learning processes, which lead to the identification of episodes of security and ...

BDNF-dependent consolidation of fear memories in the perirhinal cortex
In the recent years the perirhinal cortex (PRh) has been identified as a crucial brain area in fear learning. Since the neurotrophin BDNF (brain-derived neurotrophic factor) is an important mediator of synaptic plasticity and also crucially involved in ...

MeCP2 in cholinergic interneurons of nucleus accumbens regulates fear learning
Methyl-CpG-binding protein 2 (MeCP2) encoded by the MECP2 gene is a transcriptional regulator whose mutations cause Rett syndrome (RTT). Mecp2-deficient mice show fear regulation impairment; however, the cellular and molecular mechanisms underlying this ...
