TL;DR: The results indicate that for a given dose of methylphenidate, individual differences in DAT blockade are not the main source for the intersubject variability in MP‐induced increases in DA, which suggests that for an equivalent level of D AT blockade, MP would induce smaller DA changes in subjects with low than with high DA cell activity.

TL;DR: Evidence that expectation amplifies the effects of methylphenidate in brain and its reinforcing effects is provided and the thalamus, a region involved with conditioned responses, may mediate the enhancement of the reinforcing effects ofmethylphenidate by expectation and that the orbitofrontal cortex mediates the response to unexpected reinforcement is suggested.

TL;DR: Findings provide evidence that enhanced sensitivity of BA 25 and BA 11 in cocaine-addicted subjects may underlie the strong emotional response to the drug and the intense desire to procure it that results in craving and compulsive drug intake.

TL;DR: In this paper, the effects of exposure to radiofrequency-modulated electromagnetic fields (RF-EMF) emitted by cell phones are investigated in the brain, and the authors found that exposure to RF-EMFs from cell phones is well localized and is highest in brain regions closest to the antenna.
