Effects of deep brain stimulation on implicit learning in patients with Parkinson's disease
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis extends previous work examining the effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN) on cognitive functioning by ...
Psychophysiological assessment of motivational processing during habit learning in Parkinson's disease
(University of Missouri--Columbia, 2004)
Mesencephalic dopamine pathways have been shown to play an important role in procedural learning and motivation. Individuals with disrupted dopamine transmission due to Parkinson's disease show selective deficits in non-motor ...
Fast optical signal detected in the prefrontal lobe with near-infrared spectroscopy during sleep
(University of Missouri--Columbia, 2005)
If near-infrared spectroscopy (NIRS) is to be used in clinical applications such as the localization of epileptic foci, it must be capable of recording large amplitude transients of which only a few samples are available. ...
An evolutionary perspective of the effects of emotion on the post-auricular reflex
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The post-auricular reflex (PAR), contrary to other components of the startle reflex, is potentiated by positive emotions and inhibited by negative ...
Emotional modulation by food rewards : blink and pinna-flexion reflex amplitude while anticipating and viewing images of food
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Understanding individual differences in approaching and avoiding food cues is necessary given the rise of disorders of eating (i.e. obesity, anorexia, ...
The origin of working memory deficits in Parkinson's disease
(University of Missouri--Columbia, 2012)
Two experiments were conducted to examine the mechanisms underlying deficits of visual working memory in Parkinson's disease (PD). One study combined behavioral methods with event-related potentials (ERPs), the other, ...
Prepulse inhibition of the post-auricular reflex
(University of Missouri--Columbia, 2016)
It is well established that a weak lead stimulus will inhibit the startle response to a more intense subsequent stimulus, given an appropriate lead time (i.e. 80-400 ms). This effect is termed prepulse inhibition (PPI), ...
Event-related potential correlates of feedback anticipation during motor learning
(University of Missouri--Columbia, 2016)
Stimulus-preceding negativity (SPN), an ERP component that reflects the anticipation of feedback and other motivationally salient stimuli, has been proposed to play an important role in reinforcement learning. However, the ...
