Software Development

Welcome to Payne's Notebook! This is my notebook for a lot of things. Among them, "Research" and "Programming" are the two major parts. I hope some of my notes are usefult to you. If you have any questions or suggestions, please feel free to contact me at "".

You can find more information about me, my bookmarks, and some of my favorate photographs in "Payne Chang" section.

In "Research" section, you can find the following information.

  • Research Interests
    • My research interestes.
  • C++ Projects
    • I have developed several programs to control experiments and analyze data. You might find some of them useful to your research. Ephic is the program currently under active development.
  • Calcium Imaging
    • I use calcium-sensitive dye imaging to detect intracellular [Ca2+] change in the dendrites of neurons. Calcium imaging is also a good method to examine active events at dendrites, such as back-propagating action potentials and calcium spikes. Here you can find some of my calcium imaging galleries and notes.
  • NEURON Simulation
    • You can find some of my notes about NEURON, which is a very powerful simulation program.
  • Neurotools
    • Two JavaScript programs calculate the reversal potential (Nernst Equation) and the resting membrane potential (GHK Equation).
  • Electric Circuits
    • You can find information about RC circuits, RL circuits, series RLC circuits, parallel RLC circuits, and a cell model.
  • Equipments
    • It contains some information about my research equipments.
  • Protocols
    • Some of my experiment protocols are here.

Computer Science:

  • Programming Interests
    • I am a skilled programer. Some of my notes on C/C++, Java, Python, FLTK, OpenGL, and Igor Pro are posted here.
  • Information Technology
    • Information technology is powerful and influential. Some of my notes on HTML, CSS, JavaScript, PHP, SQL, XML, AJAX, DHTML, and HTML5 are posted here.
