Autism Spectrum Disorder (ASD) has been associated with a complex pattern of increases and decreases in resting-state functional connectivity. The developmental disconnection hypothesis ASD poses that shorter connections become overly well established development this disorder, at the cost long-range connections. Here, we investigated connectivity relatively young boys typically developing children. We hypothesized would be reduced between networks, increased within reflecting poorer...
Lesion-symptom mapping is a key tool in understanding the relationship between brain structures and behavior. However, behavioral consequences of lesions from different etiologies may vary because how they affect tissue are distributed. The inclusion would increase statistical power but has been critically debated. Meanwhile, findings lesion studies valuable resource for clinicians used across etiologies. Therefore, main objective present study was to directly compare lesion-symptom maps...
Blindsight refers to the observation of residual visual abilities in hemianopic field patients without a functional V1. Given within- and between-subject variability preserved phenomenal experience blindsight patients, fine-grained description phenomenon is still debated. Here we tested patient with established "perceptual" "attentional" (c.f. Danckert Rossetti, 2005). Using pointing paradigm MS, who suffers from complete left homonymous hemianopia, showed clear above chance manual...
White matter connections enable the interaction within and between brain networks. Brain lesions can cause structural disconnections that disrupt networks thereby cognitive functions supported by them. In recent years, novel methods have been developed to quantify extent of disconnection after focal lesions, using tractography data from healthy controls. These methods, however, are indirect their reliability validity yet be fully established. this study, we present our implementation...
Working memory and episodic are two different processes, although the nature of their interrelationship is debated. As these processes predominantly studied in isolation, it unclear whether they crucially rely on neural substrates. To obtain more insight this, 81 adults with sub-acute ischemic stroke 29 elderly controls were assessed a visual working task, followed by surprise subsequent test for same stimuli. Multivariate, atlas- track-based lesion-symptom mapping (LSM) analyses performed...
Visual deficits are common after stroke and powerful predictors for the chronic functional outcome. However, while basic visual field recognition relatively easy to assess with standardized methods, selective in primitives, such as shape or motion, harder identify, they often require a symmetrical bilateral posterior lesion order provoke full deficits. Therefore, we do not know how occur. Nevertheless, can have severe repercussions daily-life functioning. We aimed investigate prevalence...
Introduction We aimed to investigate whether associations between deficits in “mid-range” visual functions and higher-order cognitive stroke patients are more line with a hierarchical, two-pathway model of the brain, or patchwork model, which assumes parallel organization many processing routes cross-talk.Methods A group 182 ischemic was assessed new diagnostic set-up for investigation comprehensive range visuosensory mid-range functions: color, shape, location, orientation, correlated...
Objective: Visual deficits are common after stroke and powerful predictors for the chronic functional outcome. However, while basic visual field recognition relatively easy to assess with standardized methods, selective in primitives, such as shape or motion, harder identify, they often require a symmetrical bilateral posterior lesion order provoke full deficits. We aimed investigate prevalence co-occurrence of hemifield “mid-range” In addition, we looked at repercussions these mid-range on...
