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...

Impaired hippocampus-dependent and -independent learning in IL-6 deficient mice.

6 Jun 2009 Interleukin-6 (IL-6) is a cytokine that, in addition to its essential role in the function of the immune system, is present in the central nervous system (CNS). In particular, pathologically increased CNS IL-6 has been linked to impairments in ... Read more...

Impairments in fear conditioning in mice lacking the nNOS gene.

21 May 2009 The fear conditioning paradigm is used to investigate the roles of various genes, neurotransmitters, and substrates in the formation of fear learning related to contextual and auditory cues. In the brain, nitric oxide (NO) produced by neuronal ... Read more...

Technical information about 'Learning Disorders'

Definition: Conditions characterized by a significant discrepancy between an individual's perceived level of intellect and their ability to acquire new language and other cognitive skills. These disorders may result from organic or psychological conditions. Relatively common subtypes include DYSLEXIA, dyscalculia, and dysgraphia.
