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...

Ionizing radiation impairs the formation of trace fear memories and reduces hippocampal neurogenesis.

29 Sep 2009 Long-term cognitive impairments are a feared consequence of therapeutic cranial irradiation in children as well as adults. Studies in animal models suggest that these deficits may be associated with a decrease in hippocampal granule cell ... Read more...
