Neurotechnologies At The Intersection Of Criminal Procedure And Constitutional Law, Amanda C. Pustilnik
Amanda C Pustilnik
The rapid development of neurotechnologies poses novel constitutional issues for criminal law and criminal procedure. These technologies can identify directly from brain waves whether a person is familiar with a stimulus like a face or a weapon, can model blood flow in the brain to indicate whether a person is lying, and can even interfere with brain processes themselves via high-powered magnets to cause a person to be less likely to lie to an investigator. These technologies implicate the constitutional privilege against compelled, self-incriminating speech under the Fifth Amendment and the right to be free of unreasonable search and seizure …

Rapid Quantitative Pharmacodynamic Imaging By A Novel Method: Theory, Simulation Testing And Proof Of Principle, Kevin J. Black, Jonathan M. Koller, Brad D. Miller
Kevin J. Black, MD
Pharmacological challenge imaging has mapped, but rarely quantified, the sensitivity of a biological system to a given drug. We describe a novel method called rapid quantitative pharmacodynamic imaging. This method combines pharmacokinetic-pharmacodynamic modeling, repeated small doses of a challenge drug over a short time scale, and functional imaging to rapidly provide quantitative estimates of drug sensitivity including EC50 (the concentration of drug that produces half the maximum possible effect). We first test the method with simulated data, assuming a typical sigmoidal dose-response curve and assuming imperfect imaging that includes artifactual baseline signal drift and random error. With these few assumptions, …
