Ecstatic Epileptic Seizures - the Role of the Insula in Altered Self-Awareness

Ecstatic auras are a rare but compelling epileptic entity. During the first seconds of the seizure, ecstatic auras provoke feelings of well-being, intense serenity, bliss, and enhanced

Ictal alterations of consciousness during ecstatic seizures

Ecstatic Epileptic Seizures: A Glimpse into the Multiple Roles of the Insula

The role of the multiple sensory, autonomic, affective, and cognitive functions of the insular cortex, which are integrated into the creation of self-awareness, are summarized and it is suggested how this system may become dysfunctional on several levels during ecstatic aura.

Epilepsy and Ecstatic Experiences: The Role of the Insula

Ecstatic epilepsy is a rare form of focal epilepsy in which the aura (beginning of the seizures) consists of a blissful state of mental clarity/feeling of certainty. Such a state has also been

[Dostoyevsky's epilepsy in the light of recent neurobiological data].

According to new electrophysiology and imaging techniques ecstatic seizures--including the seizure onset of Dostoyevsky--could rather be connected to the insular cortex.

Validating New Technologies to Treat Depression, Pain and the Feeling of Sentient Beings: A Reply to “Neuroscience for the Soul”

A Hegelian approach to this delay of development and impedance provides a context through which the ultimate synthesis and application of this technology may be accommodated in the near future.

Predictions, perception, and a sense of self

It is proposed that the predictive or inferential perspective on brain function offers novel insights into brain diseases.

Ecstatic and gelastic seizures relate to the hypothalamus

The possible role of the insula in the epilepsy and the gambling disorder of Fyodor Dostoyevsky

It is hypothesized that the three common gambling-related cognitive distortions can be all attributed to the impairment of the anterior insular risk prediction–risk prediction error coding system.



Ictal Pleasant Sensations: Cerebral Localization and Lateralization

Ictal happiness is a localizing sign pointing to the ictal involvement of temporal mesiobasal areas in patients with focal epilepsies, and it is found that the origin of the focal epileptic activity was found in the temporal lobe.

Disproportionate Alterations in the Anterior and Posterior Insular Cortices in Obsessive–Compulsive Disorder

The results suggest the presence of unbalanced anterior and posterior insular volumetric abnormalities in unmedicated OCD patients and emphasize the distinct role of the insular cortex in different OC symptoms, which are proposed to influence the modulation of interoceptive processing in OCD patients with different symptoms.

Representation of pain and somatic sensation in the human insula: a study of responses to direct electrical cortical stimulation.

It is found that painful and non-painful somaesthetic representations in the human insula overlap, and lateralization in the right hemisphere of sites where painful sensations were evoked is coherent with the hypothesis of a preponderant role of this hemisphere in species survival.

Anterior insular volume is larger in patients with obsessive–compulsive disorder

Activation of Anterior Insula during Self-Reflection

The results provide further evidence for the specific recruitment of anterior MPFC and ACC regions for self-related processing, and highlight a role for the insula in self-reflection.

Anterior insula reactivity during certain decisions is associated with neuroticism.

It is suggested that increasing levels of neuroticism modulate neural activation in such a way that the brain interprets certainty as uncertain.

Functional alterations of large‐scale brain networks related to cognitive control in obsessive‐compulsive disorder

The findings of this study provide a novel functional imaging characterization of brain network alterations associated with cognitive‐control in OCD and raise questions about the role of patients' arousal states on the performance of cognitive imaging tasks that are otherwise assumed to be emotionally neutral.
