“…Other exclusion criteria were a significant history of drug or alcohol abuse, active drug abuse in the previous year, experience of a head trauma with loss of consciousness, and any other significant medical condition. Socioeconomic status (Hollingshead Four Factor Index, [20]), handedness (Edinburgh Inventory) [21], and total IQ (WAIS-R [22]) were also measured (see Table 1). The present study was approved by the local ethics committee (Comitato Etico Locale Indipendente Azienda Ospedaliera Ospedale Policlinico Consorziale Bari).…”

A Novel Synchronization-Based Approach for Functional Connectivity Analysis

Complex network analysis has become a gold standard to investigate functional connectivity in the human brain. Popular approaches for quantifying functional coupling between fMRI time series are linear zero-lag correlation methods; however, they might reveal only partial aspects of the functional links between brain areas. In this work, we propose a novel approach for assessing functional coupling between fMRI time series and constructing functional brain networks. A phase space framework is used to map couples of signals exploiting their cross recurrence plots (CRPs) to compare the trajectories of the interacting systems. A synchronization metric is extracted from the CRP to assess the coupling behavior of the time series. Since the functional communities of a healthy population are expected to be highly consistent for the same task, we defined functional networks of taskrelated fMRI data of a cohort of healthy subjects and applied a modularity algorithm in order to determine the community structures of the networks. The within-group similarity of communities is evaluated to verify whether such new metric is robust enough against noise. The synchronization metric is also compared with Pearson's correlation coefficient and the detected communities seem to better reflect the functional brain organization during the specific task.

Alexithymia, Verbal Ability and Emotion Recognition

et al. 2010

Although previous studies seem to indicate that alexithymic individuals have a deficit in their ability to recognize emotional stimuli, none had studied the relationship between alexithymia and verbal and non verbal abilities and their possible role in emotion recognition. The aim of the present study is to further investigate the relationship between alexithymia and emotion recognition ability. In particular we studied whether this relationship is mediated by verbal ability. Thirty-five students were selected from a group of 91 University students previously screened for alexithymia (Toronto Alexithymia Scale; TAS-20). Participants were shown black and white slides depicting facial expression of the following emotions: anger, sadness, disgust, surprise, happiness and fear. Compared to low alexithymic participants, and, more importantly, taking verbal IQ into account, high alexithymic and low alexithymic participants did not differ in emotion recognition.

Peripheral Inflammatory Markers and Antioxidant Response during the Post-Acute and Chronic Phase after Severe Traumatic Brain Injury

et al. 2016

View full text Add to dashboard Cite

Traumatic brain injury (TBI) is a mechanical insult to the brain caused by external forces and associated with inflammation and oxidative stress. The patients may show different profiles of neurological recovery and a combination of oxidative damage and inflammatory processes can affect their courses. It is known that an overexpression of cytokines can be seen in peripheral blood in the early hours/days after the injury, but little is known about the weeks and months encompassing the post-acute and chronic phases. In addition, no information is available about the antioxidant responses mediated by the major enzymes that regulate reactive oxygen species levels: superoxide dismutase, catalase, peroxidases, and GSH-related enzymes. This study investigates the 6-month trends of inflammatory markers and antioxidant responses in 22 severe TBI patients with prolonged disorders of consciousness, consecutively recruited in a dedicated neurorehabilitation facility. Patients with a high degree of neurological impairment often show an uncertain outcome. In addition, the profiles of plasma activities were related to the neurological recovery after 12 months. Venous peripheral blood samples were taken blindly as soon as clinical signs and laboratory markers confirmed the absence of infections, 3 and 6 months later. The clinical and neuropsychological assessment continued up to 12 months. Nineteen patients completed the follow-up. In the chronic phase, persistent high plasma levels of cytokines can interfere with cognitive functioning and higher post-acute levels of cytokines [interferon (IFN)-γ, tumor necrosis factor (TNF)-α, IL1b, IL6] are associated with poorer cognitive recoveries 12 months later. Moreover, higher IFN-γ, higher TNF-α, and lower glutathione peroxidase activity are associated with greater disability. The results add evidence of persistent inflammatory response, provide information about long-term imbalance of antioxidant activity, and suggest that the over-production of cytokines and the alteration of the redox homeostasis in the post-acute phase might adversely affect the neurological and functional recovery. Inflammatory and antioxidant activity markers might offer a feasible way to highlight some of the processes opposing recovery after a severe TBI.
