Area of Science:

  • Neuroscience
  • Stereology
  • Histology

Context:

  • Synaptic changes are crucial in physiological and pathological brain processes.
  • Accurate quantification of synaptic numerical density is essential for understanding brain structure and function.

Purpose:

  • To introduce and describe the disector technique for counting particles in 3D space.
  • To present computer-assisted software for quantifying synaptic numerical density using the physical director technique.

Summary:

  • The disector technique utilizes adjacent parallel tissue sections to count arbitrary particles in a defined volume.
  • The developed software, based on the physical director technique and Visual Basic 4.0, aids in automated synaptic counting.
