The Developmental Stuttering Project at Vanderbilt University studies emotional and linguistic contributions to childhood stuttering
The purpose of this presentation is to present empirical evidence on the autonomic nervous system (ANS) activity of preschool-age children who stutter (CWS). Studies have assessed differences 1) between- (i.e., CWS vs. children who do not stutter, CWNS) and 2) within-groups (i.e., association between ANS activity and stuttering frequency). Results indicate salient differences in sympathetic and parasympathetic activity at rest (e.g., lower baseline parasympathetic activity), during speech (e.g., higher parasympathetic activity), and emotional challenge (e.g., increased sympathetic activity during positive conditions). Theoretical motivation and possible implications of ANS activity in the onset, development and maintenance of stuttering will be discussed.

"The brain’s oscillatory activity influences perception and memory"
Selective attention entails an enhancement of a task-relevant stimulus or attribute; it also entails the ability to ignore irrelevant or distracting information. Cortical oscillations within the alpha (8–14 Hz) frequency band are a marker of sensory suppression. This suppression is linked to selective attention for visual, auditory, somatic, and verbal stimuli. Inhibiting the processing of irrelevant input makes responses more accurate and timely. It also helps protect material held in short-term memory against disruption. Furthermore, this selective process keeps irrelevant information from distorting the fidelity of memories. Memory is only as good as the perceptual representations on which it is based and on whose maintenance it depends. As will be discussed, alpha oscillations represent an active, purposeful mechanism that can aid paying attention and remembering things that matter.

Individual Differences in Subjective Responses to d-Amphetamine: Insights from behavioral, physiological, and neurochemical measures of dopamine signaling
Subjective responses to psychostimulants vary dramatically across individuals. Here, I will report on analyses aimed at elucidating the nature and neural underpinnings of these individual differences, and their potential implications for addiction vulnerability. First, I will discuss how individuals differ in time to peak subjective effects to oral d-amphetamine (dAMPH), assessed using the Drug Effects Questionnaire (DEQ). Based on the observation of distinct individual differences in time course of DEQ Feel, High, and Like ratings (DEQH+L+F) subjects were categorized as Early Peak Responders (peak within 60 minutes; comprising 20-25% of those studied), Late Peak Responders (peak > 60 minutes; 50-55% of subjects) or Nonresponders (20-30% of subjects). Early Peak Responders showed differences in the physiological and pharmacokinetic effects of dAMPH compared to the other groups and time to peak DEQH+L+F was negatively related to a personality trait associated with heightened addiction risk. Taken together, these data suggest that individual differences in subjective responses to dAMPH may map onto the “rate hypothesis” for drugs of abuse where faster onset of drug effects are associated with heightened potential for their abuse.
Furthermore, to investigate the role of the neurotransmitter dopamine (DA) in these subjective responses, we used Positron Emission Tomography (PET) and the radiotracer 18F-fallypride to measure dopamine D2/3 receptor availability and dAMPH-induced DA release across a subset of our subjects. Specifically, we searched in DEQH+L+F Responders for potential relationships between our DA PET measures and max self-reported drug Like, High, Feel, and Want More ratings on the DEQ. Here, we found that baseline DA receptor availability in vmPFC (a cortical area implicated in subjective valuation) positively correlated with subsequent dAMPH High. Furthermore, dAMPH-induced DA release in vmPFC, insula (involved in interoception and implicated in drug craving), and ventral striatum (previously found to correlate with dAMPH High and Wanting) was correlated with wanting more dAMPH. These findings highlight the importance of variability in DA signaling in specific paralimbic cortical regions in dAMPH’s subjective response, which may confer risk for abusing psychostimulants.
