Functional neuroimaging reveals both increases (task-positive) and decreases (task-negative) in neural activation with many tasks. Many studies show a temporal relationship between task positive and task negative networks that is important for efficient cognitive functioning. Here we provide evidence for a spatial relationship between task positive and negative networks. There are strong spatia...

Objectives: Sensory integration training plays a crucial role on the attention span and motor skills of students with Down syndrome. The present research aimed to investigate the effect of sensory integration training on the attention span and motor skills of students with Down syndrome.  Methods: This was a quasi-experimental research with a pretest, posttest design and control group. Partici...

In the presence of a continually changing sensory environment, maintaining stable but flexible awareness is paramount, and requires continual organization information. Determining which stimulus features belong together, are separate therefore one primary tasks systems. Unknown whether there global or sensory-specific mechanism that regulates final perceptual outcome this streaming process. To ...

Visual stimuli were constructed so that any given stimulus by itself appeared to be a random collection of dots. However, when 2 corresponding stimuli were superimposed by means of a 2-field tachistoscope, a 3-letter nonsense syllable was perceived. When a temporal interval was introduced between the presentation of the corresponding stimulus halves, organization in perception was found to be a...

Phantom pain after arm amputation is widely believed to arise from maladaptive cortical reorganization, triggered by loss of sensory input. We instead propose that chronic phantom pain experience drives plasticity by maintaining local cortical representations and disrupting inter-regional connectivity. Here we show that, while loss of sensory input is generally characterized by structural and f...
