Increasing evidence links exposure to stress early in life to long-term alterations in brain function, which in turn have been linked to a range of psychiatric and neurological disorders in humans. Electrophysiological approaches to studying these causal pathways have been relatively underexploited. Effects of early life stress on neuronal(More)
BACKGROUND The available pharmacotherapy for patients with epilepsy primarily address the symptoms and are ineffective in about 40% of patients. Brain inflammation gained support as potential target for developing new therapies, especially the P2X7 receptor (P2X7R), involved in processing of IL-1β, might be an interesting candidate. This study was designed(More)
Early life stress results in an enduring vulnerability to kindling-induced epileptogenesis in rats, but the underlying mechanisms are not well understood. Recent studies indicate the involvement of thalamocortical neuronal circuits in the progression of kindling epileptogenesis. Therefore, we sought to determine in vivo the effects of early life stress and(More)
OBJECTIVE The co-occurrence of absence and mesial temporal lobe epilepsy is rare in both humans and animal models. Consistent with this, rat models of absence epilepsy, including genetic absence epilepsy rats from Strasbourg (GAERS), are resistant to experimental temporal lobe epileptogenesis, in particular by amygdala kindling. Structures within the(More)
Single neuronal juxtacellular recording with simultaneous cortical electroencephalogram (EEG) in whole-animal preparations in vivo has allowed the study of the behaviour of individual neurons in relation to whole brain activity. Data on single neuron firing, neural synchrony, network behaviour and their responses to pharmacological agents can be obtained(More)
OBJECTIVES Neuroinflammation plays a critical role in the pathophysiology of mesial temporal lobe epilepsy. We aimed to evaluate whether intracerebral transplantation of interleukin 13-producing mesenchymal stem cells (IL-13 MSCs) induces an M2 microglia/macrophage activation phenotype in the hippocampus with an epileptogenic insult, thereby providing a(More)
Dysregulation in the glutamatergic function is considered a major contributor to hyperexcitatory neuronal networks in mesial temporal lobe epilepsy (MTLE). Studies in animal models of MTLE have shown positive outcomes of augmenting group 2-metabotropic receptor functions that can regulate neuronal excitability from extrasynaptic locations. To assist in(More)
