PURPOSE In recent years, there have been series analysing the electro-clinical correlations of insular epilepsy in adult populations. In contrast, the ictal semiology in children with insular epilepsy is poorly described. Considering that early and successful surgery may greatly improve the cognitive outcome and quality of life, it is worthwhile to deepen our knowledge of insular epilepsy in ch...

We have investigated molecular mechanisms of synaptic plasticity in the pathway between two forebrain structures important for taste learning, the basolateral amygdala (BLA) and the insular cortex. We report here that in vivo long-term potentiation (LTP) induced by BLA stimulation requires functional NMDA receptors and is modulated by muscarinic acetylcholine receptors. In addition, LTP results...

Positive social interaction could play an essential role in switching the preference of the substance dependent individual away from drug related activities. We have previously shown that conditioned place preference (CPP) for cocaine at the dose of 15 mg/kg and CPP for four 15-min episodes of social interaction were equally strong when rats were concurrently conditioned for place preference by...

Since tako-tsubo syndrome (TS) frequently appears soon after stroke (usually stroke involving the insular cortex), it is believed to be a consequence rather than a cause of stroke. Herein, we describe a 70-year-old woman presenting with a left middle cerebral artery stroke (involving the insular cortex) who developed a further contralateral ischemic stroke with concomitant detection of a transi...

Gustatory cortex (GC), an assemblage of taste-responsive neurons in insular cortex, is widely regarded as integral to conditioned taste aversion (CTA) retention, a link that has been primarily established using lesion approaches in rats. In contrast to this prevailing view, we found that even the most complete bilateral damage to GC produced by ibotenic acid was insufficient to disrupt postsurg...

We report the response properties of the suprasylvian opercular and insular cortices to a painful stimulation delivered by a CO(2) laser recorded by depth intracerebral electrodes in epileptic patients. We defined two cortical areas of activation in the operculo-insular cortex in response to a painful laser stimulation: a suprasylvian opercular area, where we recorded responses peaking 140-170 ...

Accumulating evidence suggests that autonomic signals and their cortical representations are closely linked to emotional processes, and that related abnormalities could lead to social deficits. Although socio-emotional impairments are a defining feature of autism spectrum disorder (ASD), empirical evidence directly supporting the link between autonomic, cortical, and socio-emotional abnormaliti...

The pathways involved in the emotional aspects of thirst, the arousal and affect associated with the generation of thirst and the motivation to obtain satiation, have been studied but remain poorly understood. Rats were therefore injected with the neurotropic virus pseudorabies in either the insular or cingulate cortex. After 2 days of infection, pseudorabies-positive neurons were identified wi...
