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...

Appetitively motivated instrumental learning in SynGAP heterozygous knockout mice.

29 Sep 2009 The synaptic Ras/Rap-GTPase-activating protein (SynGAP) regulates specific intracellular events following N-methyl-d-aspartate receptor (NMDAR) activation. Here, the impact of SynGAP heterozygous knockout (SG+/-) on NMDAR-dependent functions was ... Read more...

Fear extinction across development: the involvement of the medial prefrontal cortex as assessed by temporary inactivation and immunohistochemistry.

31 Aug 2009 Extinction in adult animals, including humans, appears to involve the medial prefrontal cortex (mPFC). However, the role of mPFC in extinction across development has not yet been studied. Given several recent demonstrations of developmental ... Read more...
