Role of dentate gyrus in aligning internal spatial map to external landmark.

23 Aug 2009 Humans and animals form internal representations of external space based on their own body movement (dead reckoning) as well as external landmarks. It is poorly understood, however, how different types of information are integrated to form a unified ... 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...

[Contemporary cognitive theories about developmental dyscalculia]

30 Jul 2009 AIM: To analyze the current theories describing the cognitive mechanisms underlying developmental dyscalculia. DEVELOPMENT: The four most researched hypotheses concerning the cognitive deficits related to developmental dyscalculia, as well as ... 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.
