This study examined neurophysiologic correlates of the perception of native and nonnative phonetic categories. Behavioral and electrophysiologic responses were obtained from Hindi and English listeners in response to a stimulus continuum of naturally produced, bilabial CV stimuli that differed in VOT from -90 to 0 ms. These speech sounds constitute phonemically relevant categories in Hindi but ...

OBJECTIVES When the clinical efficacy of spinal manipulative treatment for spinal pain has been assessed, high-velocity low-amplitude thrust (HVLAT) manipulation and mobilization have been regarded as clinical interventions giving identical and equivalent biologic effects. The objective of this review is to critically discuss previous theories and research of spinal HVLAT manipulation, highligh...

OF THE DISSERTATION Neurophysiologic Correlates to Sensory and Cognitive Processing in Altered States of Consciousness

Cochlear implants (CI) partially restore auditory sensation in deaf individuals affected by an hearing impairment >70dB. Event-related potentials (ERPs) are are brain responses automatically elicited by auditory sounds. ERPs provide information regarding several dimentions of speech sound processing, such as timing (via peak latency), accuracy/strength (via peak amplitude), size of neuronal act...

Recent studies have suggested that some variants of bipolar disorder (BD) may be due to hyperconnectivity between orbitofrontal (OFC) and temporal pole (TP) structures in the dominant hemisphere. Some initial MRI studies noticed that there were corpus callosum abnormalities within specific regional areas and it was hypothesized that developmentally this could result in functional or effective c...

November-December 2003 The title of the Institute of Medicine’s report on medical error, To Err is Human: Building a Safer Health System, is derived from Alexander Pope’s “Essay on Criticism” (1711): “To err is human; to forgive, divine” (l. 525).1 Given how familiar this proverb is in its entirety, it is striking that the IOM report itself contains no reference to forgiveness, divine or otherw...

Clearly a wakeup call for the healthcare industry, the IOM report of 2000 To Err Is Human now appears to have been a sentinel event, at least in the United States (Institute of Medicine 1999). Given that the practice of medicine in the United States is, in many ways, very similar to that in Canada--for example, our physician trainees are educated and evaluated using similar models--it is unfort...
