Prenatal maternal infection represents a risk factor for schizophrenia and related disorders. In rodents, prenatal immune challenge with the viral mimetic poly(I:C) (polyriboinosinic-polyribocytidilic-acid) induces long-term behavioral deficits, highly relevant for schizophrenia and neurodevelopmental disorders. We have previously shown that the behavioral abnormalities in mice treated with pol...

CONTEXT Perceptual closure is the ability to identify objects based on partial information and depends on the function of a distributed network of brain regions that include the dorsal and the ventral visual streams, prefrontal cortex (PFC), and hippocampus. OBJECTIVE To evaluate network-level interactions during perceptual closure in schizophrenia using parallel event-related potential (ERP)...

Dentate gyrus and hippocampus as centers for spatial learning, memory and emotional behaviour have been the focus of much interest in recent years. The molecular information on its development, however, has been relatively poor. To date, only Emx genes were known to be required for dorsal telencephalon development. Here, we report on forebrain development in the extra toes (Xt(J)) mouse mutant ...

Recent lines of research have focused on dissociating function between the dorsal and ventral hippocampus along space and anxiety dimensions. In the dorsal hippocampus, the CA1 subregion has been implicated in the acquisition of contextual fear as well as in the trace interval in trace fear conditioning. The present study was designed to test the relative contributions of dorsal (dCA1) and vent...

Epilepsy is a chronic cerebral disorder associated with recurrently occurring seizures resulting from over activity of brain neurons. Since more than one percent of the world's population is suffering from epilepsy, this disease is recognized as one of the most important neurological disorders in modern medicine. Studies indicate that impairment in balance and motor activity are known as one of...
