Reflexes of Finiteness in Romance
This dissertation investigates the concept of finiteness across Romance, a theoretical notion very frequently used within linguistics although still poorly understood (Ledgeway 2007:335). Various Romance verb forms and clauses which are not readily classifiable as either finite or non-finite are …

Modeling Gait Muscle-Reflexes Through Hindlimb Characterization in Rodents
… that comprise muscle-tendons and spinal muscle-reflexes. However, the more complex models fail to have a strong empirical basis for muscle-reflex definition and function. To garner stronger evidence for the reflex component of muscle function in gait, we modeled gait muscle-reflexes through …

Effects of Fatigue & Gender on Peroneal Reflexes After Ankle Inversion
… gender on peroneus brevis and peroneus longus reflexes after ankle inversion. A "trap-door" platform was used to elicit peroneal reflexes from sixteen males and fifteen females by suddenly inverting the ankle to 20°. Five unfatigued peroneal reflex measurements were performed before and after a …

Mechanical Monitoring of Inhibitory Jaw Reflexes in Health and Simulated Dysfunction
… with the more widely studied biphasic inhibitory reflexes evoked by stimulation of intra-oral nerves, consists of just a single phase of inhibition and usually requires the application of stimuli which excite nociceptive nerves. The aims of the present studies were to define the mechanical …

Frequency specificity of contralateral, ipsilateral and bilateral medial olivocochlear acoustic reflexes in humans
A variety of evidence indicates that the brain controls the gain of mechanical amplification in the cochlea in a frequency specific manner through the medial olivocochlear (MOC) efferent pathway, but the degree of MOC frequency specificity in humans is poorly understood. This thesis investigates …

Reflexes elicited by per-cutaneous stimulation of the medial and lateral ligaments of the knee
… current study were firstly, to investigate if reflexes can be elicited by electrical stimulation of ligaments. Secondly, to investigate if different muscles are affected differently by these reflexes. The final aim was to investigate if these reflexes can be modulated by posture or muscle …

Primitive Reflexes and Self-Regulation: Correlations Between them and the Potential Impact of Rhythmic Movements on Both
… for success at school. Unintegrated primitive reflexes make it more difficult for children to self-regulate. Although primitive reflexes are necessary for an infant’s survival, these reflexes typically become integrated in the first year of life as the child instinctively practices rhythmic …

THE EFFECTS OF GASTRIC AND HOMEOSTATIC AUTONOMIC AFFERENT REFLEXES ON CARDIAC AUTONOMIC EFFERENT ACTIVITY IN HEALTHY HUMAN VOLUNTEERS
The effects of gastric autonomic afferent reflexes on cardiovascular autonomic efferent activity are regarded as a direct neural effect of the activation of gastric receptors which send afferent inputs to the central nervous system (CNS) to cause various cardiovascular changes (Van Orshoven et al., …

Influence of Head Impact Exposure on Oculomotor Function and Pupillary Light Reflexes in Men and Women Soccer Players
Subconcussions in sport is a growing field of interest and concern as deteriorative effects of these impacts have been shown in athletes without a diagnosed concussion. Detecting subconcussions is extremely difficult and there is no standardized method to recognize these injuries. A first step in …

The impact of subclinical neck pain and its treatment on cerebellar processing as measured by the cervico-ocular and vestibulo-ocular reflexes
… The cervico-ocular and vestibulo-ocular reflexes (COR & VOR) are two measures that may be utilized to directly assess changes within the cerebellum. Utilizing two eye-tracking protocols this thesis aimed examine differences in COR gain and VOR gain adaptation in a SCNP population prior …

Assessment of the autonomic nervous system through the study of cardiovascular autonomic reflexes and their association with inflammation in three clinical settings.
Heart Rate Variability describes the beat-to-beat variation in heart rate arising from activity of the sympathetic and parasympathetic branches of the Autonomic Nervous System (ANS). Reduced ANS tone measured by reduced heart rate variability (HRV) is a powerful predictor of adverse diagnosis in …

Evaluating local skin heating as an early detection method for small-fiber neuropathy in women with breast cancer receiving paclitaxel (Taxol®)
… study were to compare the mean size of (1) axon reflexes and (2) axon flares (both markers of small fiber nerve function) in BCS receiving Taxol® to the size of reflexes/flares in healthy female controls (HCs). A third aim was to determine whether the size of axon reflexes/flares correlated with …

The effect of a reflex replication program on retained primary reflexes, motor coordination, vocabulary, visual motor ability and rapid naming in preprimary aged children
… have indicated that the retention of primary reflexes, particularly the tonic neck reflexes in young children, can result in difficulties that affect the overall functioning of the child. The retainment of reflexes may lead to clumsiness, poor eye hand coordination, poor manipulative skills …

The impact of primary motor cortex, spinal cord, and sciatic nerve cooling on spinal reflex activity in the rat: a reversible deactivation study
… a better understanding of how spinal cord reflexes and the relationship between the central and peripheral nervous systems, particularly in terms of motor control. In the anesthetized rat, recording electrodes were placed in the tibialis anterior muscle of the hindlimb to record both the …

The Unconditioned Orogastric Secretory Reflex

Prolonged Lumbar Flexion Disturbs Paraspinal Reflex Behavior
… indicates that disturbance of paraspinal reflexes may limit spinal stability. The current study aimed to examine this behavior in humans. We hypothesized that prolonged lumbar flexion will disturb paraspinal reflex behavior in human subjects. Reflex behavior was quantified following a …

Development of a Hierarchical Reflexive Control Framework for Autonomous Robotic Manipulation
