Dextroamphetamine Enhances “Neural Network-Specific” Physiological Signals: A Positron-Emission Tomography rCBF Study

open access: yes, 1996
Previous studies in animals and humans suggest that monoamines enhance behavior-evoked neural activity relative to nonspecific background activity (i.e., increase signal-to-noise ratio).

Continuous Theta Burst to Supplementary Motor Area Modulates Groove

open access: yesAnnals of the New York Academy of Sciences, Volume 1556, Issue 1, February 2026.
ABSTRACT The pleasurable urge to move to music (“groove”) has been shown to be greatest for moderately complex musical rhythms. This is thought to occur because temporal predictions from the motor system reinforce our perception of the beat when there is a balance between expectation and surprise.

Origin and Interpretation of Low Methamphetamine Levels Found in Amphetamine‐Positive Urine Samples: Support for Methylation of Amphetamine as a Minor Metabolic Pathway

open access: yesDrug Testing and Analysis, Volume 17, Issue 11, Page 2276-2282, November 2025.
A low urinary concentration of methamphetamine less than 1% of the amphetamine level may not necessarily indicate polydrug use. Instead, it could result from N‐methylation of amphetamine. Chiral analysis of both amphetamines is an effective method for distinguishing between illicit use and therapeutic sources in positive drug screening results ...

open access: yes, 2008
According to several American veterinary behaviorists, hyperactivity (“hyperkinesis”) can be distinguished from over activity by paradoxical physiological and behavioral responses of dogs given dextroamphetamine or methylphenidate (CNS stimulants).
