Full and exact adaptation to sensory rearrangement in adult human Ss requires movement-produced sensory feedback. Riesen's work suggested that this factor also operates in the development of higher mammals but he proposed that sensory-sensory associations are the prerequisite. To test these alternatives, visual stimulation of the active member (A) of each of 10 pairs of neonatal kittens was all...

ethods: Thirty-five patients with schizophrenia and 35 healthy participants were trained to associate a face with a background scene. uring testing, scenes were presented as a cue and then overlaid with three previously studied faces. Participants were asked to recall the atching face, and both eye movements and forced-choice recognition were recorded. During Non-Match trials, no faces matched ...

Behavioral and movement disorders may have antibody responses where mimicry and signal transduction may lead to neuropsychiatric abnormalities. In our study, antibodies in pediatric autoimmune neuropsychiatric disorders associated with streptococci (PANDAS) reacted with the neuronal cell surface and caudate-putamen and induced calcium-calmodulin dependent protein (CaM) kinase II activity in neu...

Over the last decade we have learned that most, if not atl, cellular behaviors are influenced by GTPases. Recent work on Ras-related GTPases that regulate the cytoskeleton has brought to our attention a new regulatory mechanism: multiple GTPase switches coupled directly in a cascade. In mammalian cells, a cascade of Cdc42 controlling Rac controlling Rho coordinates the actin cytoskeleton during...

Insulinoma is a rare endocrine tumor that can cause a wide variety of symptoms, including abnormal nocturnal behavior. We report on 3 patients with insulinoma who presented with abnormal nocturnal behavior and injury during sleep, which simulated rapid eye movement (REM) sleep behavior disorder (RBD). In case 1, the fasting glucose level was 15  mg/dL, and insulin levels were elevated (15  μU/m...

The purpose of this study was to examine individual differences in eye-movement behavior. Six metrics (Fixation Rate, Duration, and Size; Saccade Amplitude; Micro-Saccade Rate and Amplitude) were used to measure individuals' eye-movement behavior profiles (EmBP). We replicate previous research (Andrews & Coppola, 1999; Castelhano & Henderson, 2008) by finding consistent individual differences i...

Currently, measuring ethanol behaviors in flies depends on expensive image analysis software or time intensive experimental observation. We have designed an automated system for the collection and analysis of locomotor behavior data, using the IEEE 1394 acquisition program dvgrab, the image toolkit ImageMagick and the programming language Perl. In the proposed method, flies are placed in a clea...

Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by excessive muscle activity and undesirable motor events during REM sleep. RBD occurs in approximately 0.5% of the general population, with a higher prevalence in older men. RBD is a frequent feature of dementia with Lewy bodies (DLB), but is only rarely reported in Alzheimer's disease. RBD is also a risk fact...

The real-time synthesis of natural looking human movements is a challenging task in computer graphics and robotics. While dynamical systems provide the possibility to parameterize behavior in a flexible and adaptive way, the reconstruction of details of human movements with such systems is a challenge due to the large number of involved degrees of freedom. We present an approach for the synthes...

Fractal theory has been used widely for studying the scaling properties of different biological and ecological time series [1-3]. A phenomenon showinga repeating pattern at every scale is called fractal [4]. Fractals can be regular or complex [5]. In fact, fractal objects can be characterized using a scaling exponent that is called fractal dimension. Regular and complex fractals have integer an...
