Preparatory control in task-switching has been suggested to rely upon a set of distributed regions within a frontoparietal network, with frontal and parietal cortical areas cooperating to implement switch-specific preparation processes. Although recent causal evidences using transcranial magnetic stimulation (TMS) have generally supported this mode...

Hemispatial neglect is one of the most frequent attention disorders after stroke. The presence of neglect is associated with longer hospital stays, extended rehabilitation periods, and poorer functional recovery. Transcranial direct current stimulation (tDCS) is a new technique with promising results in neglect rehabilitation; therefore, the object...

Background: Social cognition abilities such as empathy and the Theory of Mind (ToM) have been shown to be impaired in neuropsychiatric conditions such as psychotic, autistic, and bipolar disorders. The endocannabinoid system (ECS) seems to play a role in social behavior and emotional processing while it also seems to play a role in those neuropsych...

Background: Although δ-9-tetrahydrocannabinol (THC), the main cannabinoid from the cannabis plant, is responsible for the psychotomimetic effects of cannabis, cannabidiol (CBD), the second most abundant cannabinoid in the cannabis plant, does not show any psychotomimetic effect. Cannabidiol has even been proposed to be antipsychotic and to counter...

Objective Abdominal fat ultrasound (US) is a simple clinical tool that may allow measures of fat depots not visible using common dual‐energy X‐ray absorptiometry (DEXA) or computerized tomography (CT) imaging. The aim of this study was to validate the technique, give measures of superficial and profound subcutaneous, preperitoneal, omental and peri...

Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation technique able to modulate cortical excitability. This modulation may influence areas and networks responsible for specific cognitive processes, and the repetition of the induced temporary changes can produce long-lasting effects. TMS effectiveness may be enhanced when used...

Human neuroimaging studies have consistently reported changes in cerebellar function and integrity in association with obesity. To date, however, the nature of this link has not been studied directly. Emerging evidence suggests a role for the cerebellum in higher cognitive functions through reciprocal connections with the prefrontal cortex. The pur...

Objective: Alzheimer's disease is a major health problem in our society. To date, pharmacological treatments have obtained poor results and there is a growing interest in finding non-pharmacological interventions for this disease. Transcranial magnetic stimulation (TMS) is a non-invasive technique that is able to induce changes in brain activity a...

Theta burst stimulation (TBS) protocols hold high promise in neuropsychological rehabilitation. Nevertheless, their ability to either decrease (continuous, cTBS) or increase (intermittent, iTBS) cortical excitability in areas other than the primary motor cortex, and their consistency modulating human behaviors with clinically relevant tasks remain...

Background: Video gaming is an increasingly popular activity in contemporary society, especially among young people, and video games are increasing in popularity not only as a research tool but also as a field of study. Many studies have focused on the neural and behavioral effects of video games, providing a great deal of video game derived brain...

Introduction Theta burst stimulation (TBS) protocols hold high promise in neuropsychological rehabilitation thanks to its ability to induce lasting effects on cortical excitability following a short delivery time. Nevertheless, its ability to inhibit (continuous protocol, cTBS) or facilitate (intermittent, iTBS) brain function from cortical areas o...

Non-invasive brain stimulation techniques, such as Transcranial Magnetic Stimulation (TMS), show promising results when used as tools for cognitive enhancement. Their ability to modulate cortical excitability with high spatial resolution makes them suitable to be paired with cognitive tasks relevant to specific brain regions. Executive functions, c...

The objective is to present a website designed to improve the quality of life of caregivers of children with cerebral palsy and show data concerning its usefulness. The website was developed in accordance with scientific literature about caregivers’ burden. We organized the website around different sections (e.g. family communication, learning to r...

Objetivos 1. Distinguir los sistemas neurales responsables de la memoria implícita y explí-cita. 2. Conocer el sustrato neural de los procesos de aprendizaje no asociativo y del priming. 3. Conocer el sustrato neural de los procesos del condicionamiento clásico y el condicionamiento instrumental. 4. Aprender los procesos neurobiológicos involucrado...

The implications of caring for a child with cerebral palsy (CP) are considerable, and parents have to cope with many changing demands related to the specific needs of their child. A new research field, devoted to the consequences of these caring tasks, has recently emerged. However, an overall vision is lacking, one that would enable us to understa...

The main objective of this research is to explore which factors best predict the occurrence of burden on primary caregivers of children with cerebral palsy (CP). Understanding these factors enables the identification of those caregivers at risk of having their physical and psychological health adversely affected, and the implementation of intervent...

The pre-supplementary motor area (pre-SMA) is considered to be a key node in the cognitive control of actions that require rapid updating, inhibition or switching, as well as working memory. It is now recognized that the pre-SMA is part of a ‘cognitive control’ network involving the inferior frontal gyrus (IFG) and subcortical regions, such as the...

Aims and objectives: To explore the quality of life and mental health of caregivers of children with cerebral palsy and to examine the impact of self-efficacy and coping strategies on these outcomes. Background: Few studies analyse the impact of caring for a child with cerebral palsy on the caregivers' quality of life besides mental health. Also...

Transcranial magnetic stimulation (TMS) is a non invasive technique of brain stimulation which could be an interesting therapeutic tool in addictive disorders, being offline repetitive TMS (rTMS) the main strategy used due to it allows to disrupt underlying brain areas and examine behavioral consequences, (Knoch et al., 2006).There are some evidenc...

Transcranial magnetic stimulation (TMS) has been applied as a therapeutic tool in clinical interventions since few years. Although first approaches were focused in rehabilitation of motor functions, nowadays some researchers and clinicians are interested in cognitive rehabilitation. Research in executive functions and TMS are really scarce in norma...

To highlight the effectiveness of transcranial magnetic stimulation (TMS) as therapeutic tool in rehabilitation of neglect. The therapeutic benefits of TMS in different neurological disorders, such as epilepsy, Parkinson's disease, stroke or dementias, are increasingly evident. For many years clinical research has been conducted to develop new and...

This study aimed to identify treatment, therapist and patient factors associated with dropping out of treatment in four outpatient mental health services. The experimental group comprised all 789 individuals who attended for the first time the mental health services during one year and dropped out of treatment in the same year or during the two fol...
