OBJECTIVE Autoantibodies against glutamic acid decarboxylase (GAD) and the voltage-gated potassium channel (VGKC) complex are associated with distinct subtypes of limbic encephalitis regarding clinical presentation, response to therapy, and outcome. The aim of this study was to investigate white matter changes in these two limbic encephalitis subtypes by means of diffusion tensor imaging (DTI)....

[3H]Thymidine autoradiography was used to investigate neurogenesis of the lateral limbic cortex and morphogenesis of the medial and lateral limbic cortices in adult and embryonic rat brains. Ontogenetic patterns in the limbic cortex are unique because some neurogenetic gradients are linked to those in neocortex, others are linked to those in paleocortex. These findings are related to hypotheses...

The current prevailing notion is that the limbic system is inextricably linked to emotion, and indeed, most textbooks, research articles, and scientific lectures tout the limbic system as being the predominant purveyor of emotional processing in the brain. Yet, more than a half-century of research has produced surprisingly little evidence in support of such a notion, suggesting that the concept...

The nucleus accumbens is a brain region in which limbic and motor inputs converge. How these information modalities shape accumbens output is not clearly understood. Here, we report that synaptic inputs from the prefrontal cortex and limbic structures interact differently depending on their timing. Coincident inputs may result in enhancing information flow through the nucleus accumbens. Respons...

Limbic P300 potentials can be recorded within the mesial temporal lobes of patients with temporal lobe epilepsy (TLE). To delineate possible mechanisms of their generation and pathological alteration, we analysed limbic P300s in 55 TLE patients with and 29 without Ammon's horn sclerosis (AHS) and correlated their amplitudes with neuronal cell counts in 30 histopathological specimens. Limbic P30...

Genetic and environmental factors influence the choices that cells make in expressing specific phenotypic features. We have examined the relative impact of these factors in controlling the fate of neurons comprising specific cerebral cortical areas using fetal tissue transplants/1,2/ and cell cultures of cortical stem cells. The limbic cortical phenotype is assayed in heterotopic and homotopic ...

The limbic system is part of an intricate network which is involved in several functions like memory and emotion. Traditionally the role of the cerebellum was considered mainly associated to motion control; however several evidences are raising about a role of the cerebellum in learning skills, emotions control, mnemonic and behavioral processes involving also connections with limbic system. In...
