Article
We report a patient with a chronic subdural/epidural hematoma superimposed to a large arachnoid cyst occupying the left frontotemporal region. Both were discovered accidentally because of a trigeminal neuralgia and concomitant subjective memory complaints. Patient’s sudden selective audioverbal memory impairment probably links to a primary cortical...

Application of a passive and fully articulated exoskeleton, called Human Body Posturizer (HBP), has been demonstrated to improve mobility, response accuracy and ambulation in multiple sclerosis (MS) patients. By using functional magnetic imaging (fMRI) during a visuomotor discrimination task, we performed a pilot study to evaluate the effect of HBP...
Article
Xenomelia is a rare condition characterized by a persistent and intense desire for amputation of one or more healthy limbs. Some frequent clinical manifestations suggest the involvement of distinct neural substrates. Specifically, recent aetiopathological hypotheses about xenomelia propose a neurodevelopmental origin, highlighting the putative cont...
Article
The neuropsychological characteristics of Idiopathic Generalized Epilepsies (IGEs) as a wide syndrome encompassing different clinical entities have been as yet not well understood. We have studied neuropsychological performance in patients suffering Juvenile Myoclonic Epilepsy (JME) and Generalized Tonic Clonic Seizures (IGE-GTCS-only) to provide i...
Article
Prediction about event timing plays a leading role in organizing and optimizing behavior. We recorded anticipatory brain activities and evaluated whether temporal orienting processes are reflected by the novel prefrontal negative (pN) component, as already shown for the contingent negative variation (CNV). Fourteen young healthy participants underw...

In this review, we explore current literature and assess evidence linking secondary (acquired) alexithymia to aberrant humor processing, in terms of their neurobiological underpinnings. In addition, we suggest a possible common neuropathological substrate between secondary alexithymia and deficits in humor appreciation, by drawing on neurophysiolog...
Article
Preparatory cortical activities were investigated in subjects with paraplegia attributed to spinal cord injury (SCI). Electroencephalogram (EEG) and behavioral data were recorded simultaneously in a visual-motor discrimination go/no-go task performed with the right upper limb. Eighteen SCI subjects participated to one, two, or three experimental se...
Article
Introduction: Literature findings on cognitive rehabilitation procedures pre-and particularly post-operatively are very scarce in epilepsy patients. Specifically, in the domain of Medial Temporal Lobe Epilepsy (MTLE) representing the most frequent type of localization-related epilepsy most of these studies have focused on postoperative cognitive in...
Article
Referred phantom sensations are frequently reported following a peripheral injury. However, very few cases describe such sensations of the ear, and it remains unclear how the aural nerve territory can be remapped to one specific peripheral nerve region. We report on a patient with brachial plexus avulsion who underwent sensory testing and was asked...
Article
Full-text available
Objective: The purpose of this study was to explore the effectiveness of a neuro-optimization intervention to determine the suitability for surgery in a patient suffering from left medial temporal lobe epilepsy (MTLE) and hippocampal sclerosis (HS). The rehabilitation program was aimed at amplifying cognitive resources and improving memory function...
Article
The pioneeristic work of Alexander Romanovic Luria into the field of human neuropsychology offered eminent contributions to clinical praxis by providing theory guided methods and instruments for the study of higher cortical functions. However, lots of this knowledge corpus either remains untranslated and thus inaccessible, or in some cases selectiv...
Article
Flexible and adaptive behavior requires the ability to contextually stop inappropriate actions and select the right one as quickly as possible. Recently, it has been proposed that three brain regions, i.e., the inferior frontal gyrus (iFg), the anterior insula (aIns), and the anterior intraparietal sulcus (aIPs), play an important role in several p...
Article
This brief work is an attempt to point to the possible common neurological breakdowns in giving rise to alexithymia, and impaired appreciation of humour. In particular, we present the case of a patient who lost the ability to enjoy humour after the surgical removal of a frontal groove meningioma, although he was still able to detect it, while at th...
Article
Full-text available
In cognitive tasks, error commission is usually followed by a performance characterized by post-error slowing (PES) and post-error improvement of accuracy (PIA). Three theoretical accounts were hypothesized to support these post-error adjustments: the cognitive, the inhibitory, and the orienting account. The aim of the present ERP study was to inve...
Article
Studies on perceptual decision-making showed that manipulating the proportion of target and non-target stimuli affects the behavioral performance. Tasks with high frequency of targets are associated to faster response times (RTs) conjunctively to higher number of errors (reflecting a response bias characterized by speed/accuracy trade-off) when com...
Conference Paper
In discriminative response tasks, researchers have largely debated about the meaning of the N2 component (which peaks approximately 250-300 ms after a stimulus) that is larger and more anterior for no-go than go stimuli (typically referred to as the “go/no-go N2 effect”). Most studies have pointed to the no-go N2 component as reflecting the respons...
Article
Deciding whether to act or not to act is a fundamental cognitive function. To avoid incorrect responses, both reactive and proactive modes of control have been postulated. Little is known, however, regarding the brain implementation of proactive mechanisms, which are deployed prior to an actual need to inhibit a response. Via a combination of elect...
Article
Full-text available
The aim of the study was to evaluate whether the presence/absence of visual cues specifying the onset of an upcoming, action-related stimulus modulates pre-stimulus brain activity, associated with the proactive control of goal-directed actions. To this aim we asked 12 subjects to perform an equal probability Go/No-go task with four stimulus configu...
Article
Full-text available
Under normal circumstances, different inner- and outer-body sources are integrated to form coherent and accurate mental experiences of the state of the body, leading to the phenomenon of corporeal awareness. How these processes are affected by changes in inner and outer inputs to the body remains unclear. Here, we aim to present empirical evidence...
Article
Objective: The aim of the present study was to investigate the cortical correlates of the intraindividual coefficient of variation (ICV) in a go/no-go task, focusing on the prefrontal cortex (PFC) contribution and evaluating both pre- and poststimulus brain activity. Method: We recorded event-related potentials (ERPs) in 40 subjects, arranged a...

Emotional perception has been extensively studied, but only a few studies have investigated the brain activity preceding exposure to emotional stimuli, especially when they are triggered by the subject himself. Here, we sought to investigate the emotional expectancy by means of movement related cortical potentials (MRCPs) in a self-paced task, in w...
Article
Full-text available
Motor performance deficits of older adults are due to dysfunction at multiple levels. Age-related differences have been documented on executive functions; motor control becomes more reliant on cognitive control mechanisms, including the engagement of the prefrontal cortex (PFC), possibly compensating for age-related sensorimotor declines. Since at...

The Rubber Hand Illusion (RHI) paradigm proved to be a powerful tool for investigating the multisensory processes underlying the ownership of a limb. A recent study that used the RHI paradigm in paraplegic patients suggests that even though illusory ownership is not affected, there is altered multisensory integration. This effect is plausibly due t...

Full-text available
Motor planning in older adults likely relies on the overengagement of the prefrontal cortex (PFC) and is associated with slowness of movement and responses. Does a physically active lifestyle counteract the overrecruitment of the PFC during action preparation? This study used high-resolution electroencephalography to measure the effect of physical...
Article
In this paper we present the case of a left-sided speech dominant patient with right medial temporal sclerosis (RMTS) and pharmacoresistant epilepsy who showed improved verbal memory during intracarotid amobarbital test (IAT) at his right hemisphere as compared with his own performance before the drug injection (baseline), as well as after right se...

Full-text available
Several cognitive changes characterize normal aging; one change regards inhibitory processing and includes both conflict monitoring and response suppression. We attempted to segregate these two aspects within a Go/No-go task, investigating three age categories. Accuracy, response times and event-related potentials (ERPs) were recorded. The ERP data...
Article
The aim of this study was to assess the influence of age-related changes in cortical activity related to the motor preparation involved in simple- and discriminative-reaction tasks. To distinguish between age effects on motor planning and stimulus processing, both movement- and stimulus-locked event related potentials (ERPs) were investigated in 14...
Article
Miraculin, the extract of miracle fruit (Richadella dulcifica or Synsepalum dulcificum), is a taste-modifying protein, its effect consisting in a temporary and almost complete replacement of sour taste with sweet taste. Despite psychophysical investigations were carried out in the past, very little is known about the effect of this molecule on tast...

Full-text available
Schizophrenics display impairments in domains of social cognition such as theory of mind and emotion recognition. Recent studies, showing that the relationship of social cognition abilities with functional outcome is more significant than other neuro-cognitive functions, have considered these abilities as a target for intervention research. This ar...
Article
Aims Disturbances in affect recognition may be one of the most pervasive and serious aspects of the schizophrenic patient's interpersonal problems. Many of the studies used chronic patients, and therefore present difficulties in interpretation of results, due to the confounding influence of institutionalization, length of disease, cognitive deficit...

Structural and functional asymmetries are present in many regions of the human brain responsible for motor control, sensory and cognitive functions and communication. Here, we focus on hemispheric asymmetries underlying the domain of social perception, broadly conceived as the analysis of information about other individuals based on acoustic, visua...
Article
Recent animal and human studies indicate the existence of a neural pathway for sound localization, which is similar to the "where" pathway of the visual system and distinct from the sound identification pathway. This study sought to highlight this pathway using a passive listening protocol. We employed fMRI to study cortical areas, activated during...
