Cell Phone Distraction Analysis Of Motor Response In A Simulated Driving Environment
… there difference between genders pertaining to motor skill while driving in a simulated driving environment? To accomplish this task, three groups of ten participants (5 women and 5 men) each were tested using a scripted test scenario focusing on left and right turns. The participants were made …

A study of event-related electrocortical oscillatory dynamics associated with cued motor-response inhibition during performance of the Go/NoGo task within a sample of prenatally alcohol-exposed children and age-matched controls
… occur due to prenatal alcohol exposure (PAE). Response inhibition refers to the ability to inhibit/suppress a prepotent behavioural tendency set in motion during an experimental task. Our research explored neocortical processing in heavy-exposed children from Cape Town, South Africa, performing …

The effects of emotional interrupt on reaction times in primary and secondary psychopathy
<p>The emotional interrupt task is presented as a motor response task that is bracketed by emotional images. The motor response task, in this study, is presented as a reaction time task. The participants either choose the left or right finger as a response to the circle or square on the screen, …

INFRARED NEURAL STIMULATION AND FUNCTIONALRECRUITMENT OF THE PERIPHERAL NERVE
… nerve interfaces have been used to restore motor function to paralyzed limbs. To restore the most natural function to paralyzed muscles requires a very selective interface. Arguably, ideal selectivity would entail independent control over each neuron. Neural interfaces based on electrical …

Exploring Interactions Between Attention and Perception in Saccadic Eye Movements and Frontal Eye Field Cell Responses
… of the processes between stimulus appearance and motor response. Conversely, compelled tasks allow the separate assessment of perceptual and motor stages of the behavioral and neural response to targets requiring top-down (CS task) or bottom-up (CO task) selection.

Eyelid conditioning in mice reveals an interaction between stress and familial Alzheimer's disease
… and modulatory processes governing cerebellar motor learning. Here, I implemented this task in head-fixed mice, then probed learning in two mouse models of Alzheimer Disease. Triple-transgenic (3xTg) animals expressing mutant Amyloid Precursor Protein, Presenilin-1 (PS1) and tau proteins were …

Being active and impulsive: the role of goals for action and inaction in self-control
… the ability to inhibit a dominant but incorrect motor response to the words “condom” and “sex”. The results demonstrate that general goals for inaction promote self-control, whereas general goals for action promote impulsive behavior. These findings are discussed in light of recent evidence …

Sex-Related Differences in Visuomotor Skill Recovery Following Concussion in Working-Aged Adults
The performance of complex visuomotor tasks in which the guiding visual information does not align spatially with the required motor output is contingent on the brain's ability to integrate somatosensory information into an appropriate motor response. Performance on such "cognitive-motor …

Functional MRI Activation of Inhibitory Control in Adolescents and Young Adults with Multiple Sclerosis
… control, defined as the ability to withhold a response, is typically preserved in patients with multiple sclerosis (MS), despite impairment in other executive functions. This study examined the concept of functional reorganization concerning inhibitory control using a simple Go/No-go (GNG) …

BEHAVIOURAL ANALYSIS OF ZEBRAFISH RELAXIN-3A MUTANT
… relaxin-3 (RLN3) has been implicated in stress responses, feeding and anxiety. Most studies have focused on the peptide encoded by the A- and B-chains, and have been conducted using rodents. This thesis explores the <i>rln3a</i> gene in zebrafish, to test whether these roles are evolutionarily …

An investigation into the formation of representational associations in visual category learning
… with a category label, and then that label to a motor response. The present study sought to examine whether there may be an additional associative stage in which a stimulus is first associated with a "category representation" – a representation of the critical characteristics of a given category …

Hemispheric Effects of Response Hand and Concurrent Auditory and Visual Information Processing on Task Performance
… hemisphere of information input, processing, and motor response. This task-hemispheric integrity has been found to exist during concurrent performance of verbal and spatial tasks, both of which are presented in a visual modality. The present study sought to examine whether task-hemispheric …

Role of DeltaC and DeltaD in Zebrafish Retinal Development
… on the zebrafish visual behavior, the visual motor response (VMR) and optokinetic reflex (OKR) of mutant embryos were analyzed. The OKR showed a reduced ability of mutant embryos to detect moving objects on their visual field, whereas each mutant presented a characteristic VMR. This study …

Resting-state Functional Connectivity Correlates of Inhibitory Control over Emotional Stimuli
… with or without intention. It is known as a motor process in which executive control suppresses an automated motor response. Currently, there is no existing research discussing the neural mechanisms of an emotional anti-saccade task, therefore with the use of resting-state functional magnetic …

Sensibilizzazione alla caffeina e sensibilizzazione all'amfetamina: influenza della suscettibilità individuale agli effetti della caffeina
… of caffeine to induce a sensitized motor response and correlated the individual susceptibility of rats to acute caffeine to the development of sensitization. Moreover, individual susceptibility to caffeine and development of motor behaviour sensitization were correlated to the …

Effects of Exposure to Perinatal Ultrasound Radiation on Information Processing in the Auditory System
… the appropriate age, they were given a locomotor task to test for appropriate motor responses. Acoustic startle and prepulse inhibition tests were administered to test for sensorimotor gating, hearing, and motor response. Finally, a brainstem auditory evoke potential test was given to track …

Sensory-motor control and adaptation in cooperative action
… a model of cooperative action wherein subsequent motor response is regressed on current error in order to improve coordination between partners. Chapter 5 shows that adaptation rate of a participant is modulated with respect to the rate of the task partner so that the net adaptation of the two …

Influence of direction and eccentricity on pro- and anti-saccade metrics
… of a sensory stimulus into an appropriate motor response, a process known as a sensorimotor transformation. The anti-saccade task can be used to investigate the ability of a subject to suppress a reflexive saccade towards a visual stimulus (pro-saccade) and generate a voluntary saccade 180° …

Individual Differences in Secondary Hyperalgesia and Associated Neural Activity
… Secondary hyperalgesia is a stable physiological response, and previous research has identified group differences in neural activity associated with an individual’s propensity to develop a small or large area of secondary hyperalgesia (Asghar et al., 2015; Werner et al., 2013). In this study, I …
