BSL Home Lessons for Single-channel Data Recorder

BSL Home guides students to record great life science data from their own bodies— heart signals (ECG), brain waves (EEG), muscle activity (EMG), eye movement (EOG), and Respiration.

Student-friendly, media-rich software provides prompts, screen shots, and lesson videos to demonstrate calibration, setup & cable management, recording procedures, and data comparison.

Tutorial-style guided lessons and active learning segments for student-designed experiments.

Experimental Objectives

L01 Electromyography (EMG) I — Standard & Integrated EMG
Students investigate the properties of skeletal muscle by measuring maximum clench strength.

L02 Electromyography (EMG) II — Motor Unit Recruitment & Fatigue
Students lift weights to examine motor unit recruitment and skeletal muscle fatigue.

L03 Electroencephalography (EEG) I —Relaxation & Brain Rhythms
Introduces students to electroencephalography by recording from the occipital lobe.

L04 Electroencephalography (EEG) II — Alpha Rhythms in the Occipital Lobe
Students discover how the brain constantly receives and integrates sensory input.

L05 Electrocardiography (ECG) I — Components of the ECG
Introduces students to electrocardiography and the recording of the heart’s electrical signals. Bipolar Leads, Einthoven’s Law, Mean Electrical Axis on the Frontal Plane. Explains Einthoven’s triangle while students perform tasks designed to change the rhythm of the heart.

L08 Respiratory Cycle I — Respiratory Rates, Relative Depths of Breathing, Regulation of Ventilation
Students observe and record EMGs from thoracic respiratory skeletal muscle during eupnea and voluntary apnea.

L10 Electrooculogram (EOG) I — Eye Movement; Saccades & Fixation
Students record horizontal eye movements during real and simulated tracking of a pendulum.

L14 Biofeedback —Relaxation & Arousal
Explores the concept of biofeedback training and its effect on autonomic control of heart rate.

L15 Aerobic Exercise Physiology — Cardiovascular & Respiratory Adjustments During and After Exercise
Students record ECG and HR to see how the electrical activity of the heart and heart rate change.

Tasks Performed by the Student

L01 Electromyography (EMG) I

  • Record EMG from the dominant and non-dominant forearms.
  • Clench fist four times, increasing the grip each time to reach the maximum grip strength with the fourth clench.
  • Listen to the sound of the EMG.

L02 Electromyography (EMG) II

  • Record EMG from the dominant and non-dominant forearms.
  • Complete at least three cycles of lift-wait-repeat with increasing weight.
  • Lift the maximum weight to 45 degrees and hold it until the onset of fatigue.

L03 Electroencephalography (EEG) I

  • Record EEG from the occipital lobe.
  • Record EEG from a relaxed subject with eyes closed, eyes open, and eyes closed again.

L04 Electroencephalography (EEG) II

  • Record EEG data from the occipital lobe.
  • Lie down and relax with eyes closed.
  • Perform a mental word exercise.
  • Hyperventilate for two minutes.
  • Open eyes and continue to relax.

L05 Electrocardiography (ECG) I

  • Record Lead II ECG.
  • Event mark each new activity.
  • Lie down and relax.
  • Seated and relaxed.
  • Take 5 deep breaths.
  • Perform a physical exercise to increase the heart rate.
  • Relax while heart rate returns to normal.
L08 Respiratory Cycle I

  • Record respiration.
  • Sit down and relax.
  • Hyperventilation and recovery (2 min).
  • Breathe normally for 20 seconds, hold breath for as long as possible, breathe normally for 20 seconds.
  • Hyperventilate for 20 seconds and hold breath as long as possible.

L10 Electrooculogram (EOG) I

  • Record horizontal EOG.
  • Hold a pendulum and track with eyes until pendulum stops swinging.
  • Track an imaginary pendulum with eyes.
  • Read a passage of text silently.
  • Read a passage of text aloud.

L14 Biofeedback

  • Record ECG and Heart Rate.
  • Seated, recording baseline for 20 seconds.
  • Concentrate on relaxation for 2 min (i.e., think of something relaxing).
  • Concentrate on arousal for 2 min (i.e., think of something stressful or exciting).
  • Watch a presentation of relaxing images or video for 2 min.
  • Watch a presentation of unsettling images or video for 2 min.

L15 Aerobic Exercise Physiology

  • Record ECG and Heart Rate.
  • Seated, recording baseline for 20 seconds.
  • Exercise for three minutes.
  • Recover in seated position until Heart Rate returns to baseline.
