VEP Lesson Updated

BIOPAC's Visual Evoked Potential lesson guides students to record a baseline and two experimental Visual Evoked Potentials segments.

H22 Visual Evoked Response 

Each experimental segment presents a visual stimulus to a human subject and runs at least one minute so that over 100 strobe flashes (at 2 Hz rate) are output and the BSL System records at least one hundred electrical responses from the subject's visual nervous system. A typical VEP response comprises a well-defined peak at around 100 milliseconds; this peak is often called P100.

This VEP lesson (P100 test) uses a Biopac Student Lab System, stroboscope, and lead set with disposable electrodes. The lesson has been updated to use enhanced setup and measurement features available in the current release of Biopac Student Lab. It's easy to add recording segments or analysis for further investigation.

fNIRS Data Analysis

In this fNIRS training, you will see a typical analysis workflow for fNIRS data in experiments featuring both event-based and continuous stimulation. Learn about a powerful yet easy-to-use software package with both a graphical user interface and scripting capability (for automation).

What You Will Learn:
• Preparing data for analysis
• Signal conditioning, noise removal, and managing artifacts
• Best practices for visualizing recorded data
• Block analysis using event markers and/or time
• Further temporal and spatial processing of data, including cell-by-cell processing
• Automation of analysis procedures
• Performing common statistical comparisons (t-test, ANOVA)
• Spatial visualization
