Gaming-addicted teens identify more with their cyber-self than their own self: neural evidence
Self-concept, as a stable essence, is based on the beliefs of individual's cognitive uniqueness, constancy and continuity (Erikson, 1959; Yi, 2002). Recognizing oneself as a being with cognitive, social and emotional characteristics distinct from other people is a starting point of self-awareness and a basis of self-knowledge.

Elevated hippocampal choline level is associated with altered functional connectivity in females with major depressive disorder: a pilot study
Major depressive disorder (MDD) is a severe worldwide public health problem, characterized by persistent low mood and anhedonia (Kupfer et al., 2012). Dysfunction of the limbic-cortical pathway, which dominates emotion processing and regulation, plays an important role in MDD pathophysiology (Hamilton et al., 2011; Mayberg, 2003). As one of the most influential network models of MDD, the limbic-cortical model suggests abnormal reciprocal interactions between the limbic system and the cortex in MDD, resulting in affective and cognitive abnormalities (Kaiser et al., 2015).

Neuroimaging investigations of dorsal stream processing and effects of stimulus synchrony in schizophrenia
Impairments in perception are recognized as a core deficit of schizophrenia (Green  et al., 2004). These include specific deficits in auditory and visual processing (Rojas et al., 2002; Williams et al., 2011; Butler et al., 2008). However, it remains unclear how these types of unisensory deficits impact cognitive functioning and behavioral outcomes in schizophrenia patients ( SP) despite studies implicating links. Multisensory integration (MSI) represents an important extension to studies of unisensory processing. (Source: Psychiatry Research: Neuroimaging)

Formal thought disorder is related to aberrations in language-related white matter tracts in patients with schizophrenia
Formal thought disorder (FTD) is a severe language disturbance and a core syndrome of schizophrenia (Bleuler, 1958). This syndrome, however, is not only found in schizophrenia or schizoaffective disorders, but also in the general population, in people at high risk of developing psychosis, and in people with non-psychotic disorders (Roche et al., 2015). Therefore, FTD should be considered as both a dimensional entity of speech pathology and a categorical entity in terms of a trait marker for psychosis (Roche et al., 2015).

Structural and functional alterations of the suicidal brain: an updated review of neuroimaging studies
Brain imaging is a non-invasive and in vivo direct estimation of detailed brain structure, regional brain functioning and estimation of molecular processes in the brain. The main objective of this review was to systematically analyze functional and structural neuroimaging studies in individuals at risk for suicide. We reviewed articles published between 2005 and 2018, indexed in PubMed and Medline, assessing structural and functional alterations of the brain of individuals at high risk for suicide and at low risk for suicide.

Trait and state anxiety is marked by increased working memory-related parietal BOLD signal
Anxiety disorders are closely associated with compromised cognitive and behavioural functions, and this compromised functionality has neurological underpinnings (Stefanopoulou et al., 2014). Cognitive functions, such as working memory, are modulated by the cognitive control network, and this network has been shown to be compromised at clinical and non-clinical levels of anxiety (Moran, 2016; Vytal et al., 2012), suggesting a spectrum of associated neurological deficits. As such, utilising non-clinical, unmedicated populations in the identification of anxiety-related neural markers may aid in the development of preventative...

fMRI Classification Method with Multiple Feature Fusion Based on Minimum Spanning Tree Analysis
The human brain is a complex system with a sophisticated structure. As a non-invasive way to measure spontaneous neural activity in the human brain, resting-state functional magnetic resonance imaging has attracted considerable attention (Fox et al., 2007; Wang et al., 2010). Resting-state fMRI using blood oxygenation level dependent (BOLD) signals as neurophysiological indicators can detect spontaneous low-frequency brain activity and has been successfully applied to the diagnosis of neuropsychiatric diseases such as epilepsy (Horstmann et al., 2010; Raj et al., 2010), Alzheimer's disease (AD) (He et al., 2008; Stam, 2010...

Anterior Thalamic Radiation Structural and Metabolic Changes in Obsessive-Compulsive Disorder: A Combined DTI-MRS Study
Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder with 1% ∼ 3% prevalence in general population, characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions) (Calkins et al., 2013; Rasmussen and Eisen, 1992; Ruscio et al., 2010). World Health Organization (WHO) has ranked OCD as one of the top ten disabling chronic diseases. Th e obsession and compulsion symptoms interfere severely with cognitive function and cause emotional maladjustment. (Source: Psychiatry Research: Neuroimaging)

Longitudinal changes in the mismatch field evoked by an empathic voice reflect changes in the empathy quotient in autism spectrum disorder
Empathy is the ability to understand and share another person's inner life, and it is an essential process in social cognition. Recent studies have focused on the difficulty of cognitive empathy (Baron-Cohen and Wheelwright, 2004; Mazza et al., 2014) and emotional empathy (Fridenson-Hayo et al., 2016; Trimmer et al., 2017) in individuals with ASD. It has been proposed that social interactive and communicative problems can be attributed to impairments in empathy (Baron-Cohen, 2002). Auditory mismatch negativity (MMN) or its magnetic mismatch field (MMF) (Sams, 1991) has been used as a neurophysiological marker for the integ...

Emotion introspection and regulation in depression
Being aware of and voluntarily controlling and guiding one's own mental states are highly evolved human capabilities (Heatherton,  2011). These abilities, however, may be impaired in mental disorders such as depression. Depression is characterized by difficulties in controlling unpleasant emotions and thoughts (DeRubeis et al., 2008; Disner et al., 2011). Neural models of impaired emotional processing in depression implicat e amygdala hyperactivity and impaired emotion regulation related to dysfunction of the medial and dorsolateral prefrontal cortex (MPFC, DLPFC (DeRubeis et al., 2008; Disner et al., 2011; Holmes etÂ...

Parkinsonism is associated to fronto-caudate disconnectivity and cognition in schizophrenia
The present work studies the possible relation of parkinsonism and fronto-caudate dysconnectivity, as well as its relation to cognition in schizophrenia patients. We assessed parkinsonism using Simpson-Angus scale and prefronto-caudate connectivity using diffusion magnetic resonance in 22 schizophrenia patients (11 first-episodes) and 14 healthy controls. Fractional anisotropy was calculated for the white matter tracts directly linking rostral middle prefrontal (RMPF) and superior medial prefrontal (SMPF) regions with caudate nucleus.

A semi-automated algorithm for hypothalamus volumetry in 3 Tesla magnetic resonance images
The hypothalamus, a small diencephalic gray matter structure, is part of the limbic system. Volumetric changes of this structure occur in psychiatric diseases, therefore there is increasing interest in precise volumetry. Based on our detailed volumetry algorithm for 7 Tesla magnetic resonance imaging (MRI), we developed a method for 3 Tesla MRI, adopting anatomical landmarks and work in triplanar view. We overlaid T1-weighted MR images with gray matter-tissue probability maps to combine anatomical information with tissue class segmentation. (Source: Psychiatry Research: Neuroimaging)

Prefrontal Cortex Activation During Cognitive Interference in Nonsuicidal Self-Injury
Nonsuicidal self-injury (NSSI) is deliberate behavior resulting in self-inflicted damage without suicidal intent. Although skin cutting is most common (Nock,  2009a), many engage in multiple methods of NSSI (Victor& Klonsky,  2014), including scratching, picking, burning, bruising, etc. (Hooley, 2008; Nock, 2009b). NSSI is common, with 5.9% of adults (Klonsky, 2011) and up to 23% of adolescents reporting a history of NSSI (Jacobson& Gould,  2007). Adolescent females are three times more likely to engage in NSSI than males (Barrocas et al., 2012). (Source: Psychiatry Research: Neuroimaging)
