Using Extracellular Single-unit Electrophysiological Data as a Substrate for Investigative Laboratory Exercises

Area of Science:

• Neuroscience
• Physiology
• Science Education

Background:

• Laboratory science courses aim to develop problem-solving, reasoning, and data fluency.
• Integrating authentic research problems enhances student engagement and learning.
• Extracellular single-unit electrophysiology offers rich data for investigatory exercises.

Purpose of the Study:

• To explore the use of extracellular single-unit electrophysiological data in student investigatory exercises.
• To enhance problem-solving, data fluency, and integrative thinking in science education.
• To provide a framework and resources for implementing such exercises.

Main Methods:

• Overview of extracellular single-unit recording techniques.
• Discussion of single-unit data file organization.
• Description of a multi-week laboratory module using electrophysiological data.

Main Results:

• The module was successfully administered in an intermediate-level laboratory course.
• Suggestions for varied exercise scopes (limited to advanced projects) were provided.
• A companion website with resources (software, sample data) was developed.

Conclusions:

• Extracellular single-unit electrophysiology data can effectively support student investigatory exercises.
• This approach fosters key scientific skills and promotes an integrative view of science.
• Resources are available to facilitate the adoption of these novel laboratory exercises.
