Contextual and Temporal Modulation of Extinction: Behavioral and Biological Mechanisms.
TL;DR: Research on the behavioral and neurobiological mechanisms of contextual influences on extinction learning and retrieval is reviewed, with particular attention to the effects of recent trials and trial spacing.

Inactivation of the infralimbic but not the prelimbic cortex impairs consolidation and retrieval of fear extinction.
TL;DR: Results show for the first time that neuronal activity in the PL is involved in the expression of fear responses but not in the learning that underlies long-term fear inhibition, and show that the IL is critical for consolidation and retrieval of this inhibitory learning.
Reinstatement of fear to an extinguished conditioned stimulus: two roles for context
R. Frederick Westbrook,Mihaela D. Iordanova,Gavan P. McNally,Rick Richardson,Justin A. Harris +4 more
TL;DR: Findings suggest 2 roles for context in reinstatement: conditioning of the test context and mediated conditioning by the extinction context.
Psychological and neural mechanisms of experimental extinction: a selective review.
TL;DR: It is suggested that many of the signature characteristics of extinction learning can be accommodated by the standard associative learning theory assumption that extinction results in partial erasure of the original learning together with new inhibitory learning.

The effect of high fat, high sugar, and combined high fat-high sugar diets on spatial learning and memory in rodents: A meta-analysis.
TL;DR: The meta-analyses showed that each type of diet and task adversely affected performance, with the largest effect produced by exposure to a combined high fat-high sugar diet and the use of the radial arm maze to assess the effect of such diets on cognition.
