Diffusion tensor imaging (DTI) is a magnetic resonance modality that permits to characterize the orientation and integrity of white matter (WM). DTI-based tractography techniques, allowing the virtual reconstruction of WM tract pathways, have found wide application in preclinical neurological research. Recently, anatomically detailed rat brain atlases(More)
Derangements of cortical development can cause a wide spectrum of malformations, generally termed 'cortical dysplasia' (CD), which are frequently associated with drug-resistant epilepsy and other neurological and mental disorders. 1,3-Bis-chloroethyl-nitrosurea (BCNU)-treated rats represent a model of CD due to the presence of histological alterations(More)
Cortical dysplasias (CDs) include a spectrum of cerebral lesions resulting from cortical development abnormalities during embryogenesis that lead to cognitive disabilities and epilepsy. The experimental model of CD obtained by means of in utero administration of BCNU (1-3-bis-chloroethyl-nitrosurea) to pregnant rats on embryonic day 15 mimics the(More)
OBJECTIVE Cortical dysplasias (CDs) represent a wide range of cortical abnormalities that closely correlate with intractable epilepsy. Rats prenatally exposed to 1-3-bis-chloroethyl-nitrosurea (BCNU) represent an injury-based model that reproduces many histopathologic features of human CD. Previous studies reported in vivo hyperexcitability in this model,(More)
Kir4.1 is the principal K(+) channel expressed in glial cells. It has been shown that it plays a fundamental role in K(+)-spatial buffering, an astrocyte-specific process where excess extracellular concentration of K(+) ions, generated by synaptic activity, is spatially redistributed to distant sites via astrocytic syncytia. Experimental and clinical(More)
