Two-Point Threshold Experiment

Auditory cortex and basilar membrane.Auditory cortex and basilar membrane.

In this class activity, students will measure the two-point threshold in order to increase their understanding of the magnification principle and how touch is mapped in the sensory cortex of the human brain. Students will also apply their understanding of statistical concepts (random and systematic error, Gaussian distributions) to actual data from previous Frontiers of Science seminars. This document serves as an instructor guide; student handouts are provided in accompanying documents.
