    Related ArticlesHighly Integrated FPGA-only Signal Digitization Method Using Single-ended Memory Interface Input Receivers for Time-of-Flight PET Detectors. IEEE Trans Biomed Circuits Syst. 2018 Aug 15;: Authors: Won JY, Lee JS Abstract We propose a new highly integrated FPGA-only signal digitization method for individual signal digitization of time-of-flight positron emission tomography (TOF PET). We configured I/O port of the FPGA with a single-ended memory interface (SeMI) input receiver. The SeMI is a single-ended voltage-referenced interface that has a common reference voltage per I/O Bank, such that each SeMI input receiver can serve as a voltage comparator.

  • The effect of cathodal transcranial direct current stimulation during rapid eye-movement sleep on neutral and emotional memory.
    Related ArticlesThe effect of cathodal transcranial direct current stimulation during rapid eye-movement sleep on neutral and emotional memory. R Soc Open Sci. 2018 Jul;5(7):172353 Authors: Johnson JM, Durrant SJ Abstract Sleep-dependent memory consolidation has been extensively studied. Neutral declarative memories and serial reaction time task (SRTT) performance can benefit from slow-wave activity, characterized by less than 1 Hz frequency cortical slow oscillations (SO). Emotional memories can benefit from theta activity, characterized by 4-8 Hz frequency cortical oscillations. Applying transcranial direct current stimulation (tDCS) during sleep entrains specific frequencies to alter sleep architecture. When applying cathodal tDCS (CtDCS), neural inhibition or excitation may ... read more
