To enable accurate measurement of neuronal and synaptic parameters.
To provide a flexible and adaptable system for diverse research needs.

Main Methods:

Utilizing a microcomputer system with a digitizer to trace biological profiles from micrographs.
Calculating morphological parameters such as cross-sectional area, perimeter, average diameter, and form factor.
Inputting data on profile contacts, elements, type, and depth for density calculations.

Main Results:

The system successfully quantifies biological profiles, including neurons and synapses.
Calculations include morphological features and derived densities (contact and element).
Data can be stored on magnetic tape or floppy disk and printed.

Conclusions:

The developed microcomputer system provides an efficient and quantitative method for analyzing biological profiles.
The system's reliance on commercially available hardware and BASIC software ensures adaptability.
This tool has the potential to significantly advance quantitative neuroscience and related fields.
