Cognitive Demands During Quiet Standing Elicit Truncal Tremor in Two Frequency Bands: Differential Relations to Tissue Integrity of Corticospinal Tracts and Cortical Targets

Natalie Zahr, Adolf Pfefferbaum

Given the complexity of sensorimotor integration invoked to maintain upright posture, the integrity of supratentorial brain structures may also contribute to quiet standing and consequently be vulnerable to interference from cognitive challenges.

Dynamic Responses of Selective Brain White Matter Fiber Tracts to Binge Alcohol and Recovery in the Rat

Adolf Pfefferbaum, Natalie Zahr

To determine the dynamics of white matter vulnerability to excessive alcohol consumption, diffusion tensor imaging (DTI) was used in an animal model of alcohol exposure.

Imaging Neuroinflammation? A Perspective from MR Spectroscopy

SRI International, Natalie Zahr, Adolf Pfefferbaum

The present MRS study was conducted in four groups: alcohol dependent, HIV-infected, alcohol dependent + HIV infected and healthy control individuals to determine whether metabolites would change in a pattern reflecting neuroinflammation.

In Vivo Glutamate Measured with Magnetic Resonance Spectroscopy: Behavioral Correlates in Aging

Natalie Zahr, Adolf Pfefferbaum

To investigate the contribution of regional glutamate levels to behavior in the aging brain, we used an in vivo magnetic resonance spectroscopy protocol optimized for glutamate detection in 3 brain regions targeted by cortical glutamatergic efferents—striatum, cerebellum, and pons.
