Article
Full-text available
Precise localization of eloquent cortex in children may provide much needed surgical guidance and expand surgical epilepsy treatment options. It reduces the risk of postsurgical functional deficits and benefits children’s quality of life, educational capacity, and long-term employment potential. The ultimate goal of functional mapping for pediatric...
Article
Full-text available
Accurate localization of brain regions responsible for language and cognitive functions in Epilepsy patients should be carefully determined prior to surgery. Electrocorticography (ECoG)-based Real Time Functional Mapping (RTFM) has been shown to be a safer alternative to electrical cortical stimulation mapping (ESM), which is currently the clinical...
Chapter
RATIONALE: Electrocorticography-based functional language mapping (ECoG-FLM) utilizes an ECoG signal paired with simultaneous language task presentation to create functional maps of the eloquent language cortex in patients selected for resective epilepsy or tumor surgery. At present, the concordance of functional maps derived by ECoG-FLM and electr...
Article
Full-text available
The success of surgical resection in epilepsy patients depends on preserving functionally critical brain regions, while removing pathological tissues. Being the gold standard, electro-cortical stimulation mapping (ESM) helps surgeons in localizing the function of eloquent cortex through electrical stimulation of electrodes placed directly on the co...
Article
Full-text available
A common magnitude system for the processing of time and numerosity, supported by areas in the posterior parietal cortex, has been proposed by some authors. The present study aims to investigate possible intersections between the neural processing of non-numerical (time) and numerical magnitudes in the posterior parietal lobe. Using Magnetoencephal...
Chapter
The first chapter of this book readers introduced BCIs, the BCI Award Foundation and 2022 jury, the procedures and criteria of the awards, and the 12 nominees in 2022. Most chapters described projects that were nominated for a BCI Research Award. This is the last chapter of the book. Here, we provide more information about the awards ceremony and t...
Chapter
With brain-computer interfaces (BCIs), people can send information directly from their brains to computers. People can use BCIs to send messages or commands without moving. In 2010, we launched the Annual BCI Research Awards. People submit their projects to a jury that scores each project on many criteria and then selects the best projects from tha...
Chapter
Stroke is a major cause of disability resulting in multiple system impairments. Limited extended care resulted in prioritizing high level repetitions of task-specific activities to improve function. One such modality is BCI to drive motor rehabilitation. While several systematic reviews and meta-analyses highlight the benefits of utilizing BCIs to...
Conference Paper
Dreams are often forgotten despite their impact on our emotions and memory. In our pursuit of developing an objective dream-content recording methodology (reaDream), we focused on the motor imagery (MI)-related dream component, which is reported to be present in dreams along with other sensory, perceptual, and cognitive phenomena. It has been shown...

Full-text available
Description In this review article, we aimed to create a summary of the effects of internal variables on the performance of sensorimotor rhythm-based brain computer interfaces (SMR-BCIs). SMR-BCIs can be potentially used for interfacing between the brain and devices, bypassing usual central nervous system output, such as muscle activity. The carefu...

Description Sensorimotor rhythm-based brain-computer interfaces (SMR-BCIs) are used for the acquisition and translation of motor imagery-related brain signals into machine control commands, bypassing the usual central nervous system output. The selection of optimal external variable configuration can maximize SMR-BCI performance in both healthy and...
Chapter
In this chapter, the authors reflect on the uses of MEG to better characterize different cortical zones within the epileptic network. First, they review the role of MEG in the presurgical workout under the classical model of epileptic zones. Under this model, MEG had been incorporated as a noninvasive tool to define the irritative zones based on re...

Article
Auditory steady-state response (ASSR) at 40Hz has been proposed as a potential biomarker for schizophrenia. The ASSR studies in patients have used click stimulation or amplitude-modulated tones. However, the sensitivity of 40Hz ASSRs to different stimulation types in the same group of patients has not been previously evaluated. Two stimulation type...

Electrical cortical stimulation (ECS) is often used in presurgical evaluation procedures for patients suffering from pharmacoresistant epilepsy. Real-time functional mapping (RTFM) is an alternative brain mapping methodology that can accompany traditional functional mapping approaches like ECS. In this paper, we present a combined RTFM/ECS system t...

Employing a lexical decision task (LDT), participants determined whether or not two visually presented letter strings were words. Our novel approach used LDT trials to examine influences upon subsequent recognition of thematically-related items. LDT trials involving words semantically related to DRM lists robustly primed false recognition of critic...

Full-text available
Simultaneous bilateral onset and bi-synchrony epileptiform discharges in electroencephalogram (EEG) remain hallmarks for generalized seizures. However, the possibility of an epileptogenic focus triggering rapidly generalized epileptiform discharges has been documented in several studies. Previously, a new multi-stage surgical procedure using bilate...

In one form of the lexical decision task (LDT), participants determine on each trial whether or not two visually presented letter strings are words. Our approach involved using LDT trials to influence subsequent recognition performance on thematically-related DRM lists. Specifically, LDT trials that involve words semantically related to DRM lists p...
Article
Full-text available
Although a number of studies have demonstrated state-related dependence of auditory steady-state responses (ASSRs), the investigations assessing trait-related ASSR changes are limited. Five consistently identified major trait dimensions, also referred to as "big five" (Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness), are c...
Conference Paper
Full-text available
Introduction: There is evidence to suggest that surgically-implanted intracranial BCIs might be more efficient than scalp-based BCIs, especially for severely disabled patients. However, before moving into invasive implantation of BCIs, the important question must be addressed – localization of the areas for implantation, which might vary dependent...
Article
Increasing evidence indicates that the brain generates signals in a wide-frequency range, including high-frequency brain signals. High-frequency brain signals are also called high-frequency oscillations (HFOs), ripples, or fast ripples. There are no established terms for describing HFOs in a variety of frequency ranges. HFOs are clinically importan...

The auditory steady-state response (ASSR) is observed when stimuli are presented periodically resulting in electroencephalographic entrainment (Picton et al. 2003), i.e. the frequency of the ASSR is close to the frequency of stimulation and the greatest magnitude is observed when stimuli are presented at 40 Hz (Galambos et al. 1981). Since its disc...

uditory steady-state responses (ASSRs) are widely applied to test brain's ability to follow external stimulation in neuropsychiatric disorders. It is known that ASSRs are related to GABAergic transmission. Female sex steroid homones - both estrogens and progesterone - affect functioning of GABAergic system. However, it is not known how these hormon...

Article
Abnormalities in attention, memory and information processing are considered to be the primary deficits in schizophrenia. Event-related potential (ERP) P300 could reflect deficits in auditory information processing related to active attention in schizophrenia patients. Atypical antipsychotics tend to ameliorate cognitive deficits, however their eff...

Cognitive dysfunction is considered to be a core feature in schizophrenia. It is believed that antipsychotic drugs, especially atypical ones, could improve cognitive functions in schizophrenia patients. Auditory event-related potentials (ERPs) such as mismatch negativity (MMN) and P300 response are potential candidates for objective investigation o...
