Factors governing single-trial contextual fear conditioning in the weanling rat.

29 Sep 2009 Although contextual fear conditioning emerges later in development than explicit-cue fear conditioning, little is known about the stimulus parameters and biological substrates required at early ages. The authors adapted methods for investigating ... Read more...

Inactivation of the infralimbic but not the prelimbic cortex impairs consolidation and retrieval of fear extinction.

23 Aug 2009 Rats were subjected to one or two cycles of context fear conditioning and extinction to study the roles of the prelimbic cortex (PL) and infralimbic cortex (IL) in learning and relearning to inhibit fear responses. Inactivation of the PL depressed ... Read more...

Aversion- vs fear-inducing properties of 2,4,5-trimethyl-3-thiazoline, a component of fox odor, in comparison with those of butyric acid.

30 Jul 2009 2,4,5-trimethyl-3-thiazoline (TMT), a component of fox feces, is a widely used odorant to induce innate fear behavior in rats and mice. However, based on the slight acrid smell it was argued that the observed behavioral effects are a result of the ... Read more...
