| Introduction to LabTutor |
Familiarization with LabTutor software and PowerLab hardware. Basic features of acquisition, analysis and reporting are covered using LabTutor. |
| Blood Pressure |
Students will measure blood pressure using a sphygmomanometer and stethoscope or microphone. They will also assess changes in peripheral circulation and the effects of cuff location. |
| Breathing |
Students investigate the effects of breath holding, hyperventilation and rebreathing using a respiratory belt transducer around the abdomen. The relation between breathing and heart rate are also studied. |
| Cardiorespiratory Effects of Exercise |
In this laboratory, students will record the electrocardiogram (ECG), blood pressure and respiratory movements from a healthy volunteer, and compare the recordings made when the volunteer is at rest, during exercise and immediately after exercise. |
| Cardiovascular Effects of Exercise |
Study how heart rate and finger pulse change after different exercise regimes. Students will determine the factors that control heart rate and blood flow to tissues before, during and after exercise. |
| The Diving Response |
Investigate the effects of the diving response on heart rate and peripheral circulation in humans during simulated dives as well as breath holding. |
| ECG & Heart Sounds |
Record and identify the major components of the human ECG as well as timings of these components. Students will correlate heart sounds, components of the ECG with mechanical activity of the heart. |
| Energy Expenditure and Exercise |
Students will investigate ventilation and gas exchange at three different levels of exercise and calculate the rate of metabolic energy consumption as a function of mechanical energy expenditure. |
| ECG & Peripheral Circulation |
Students measure and analyze ECG and pulse at rest as well as investigating the blood supply to the fingers from the radial and ulnar arteries. |
| Electroencephalography (EEG) |
Students will record and analyze electroencephalograms (EEGs). The effect of opening and shutting the eyes, auditory and mental cues on alpha and beta waves will be examined . |
| Electromyography (EMG) |
Record EMG and investigate how contractile force changes with increasing demand. Examine the activity of antagonist muscles, coactivation and measuring nerve conduction velocity. |
| Electro-oculography (EOG) |
Record the electrical activity (EOG) associated with eye movements, recognize common artifacts in EOG recordings. Measure and understand the significance of angular displacement measurements, smooth tracking and investigate aspects of gaze holding. |
| Gut Absorption |
In this experiment, students will investigate how the gut handles a carbohydrate load presented as either glucose or starch. Measurements are made of blood glucose at 15 minute intervals using a glucolet and glucometer. |
| Mechanics of Ventilation |
In this laboratory students examine mechanical properties of the lung and chest wall by measuring pressures generated passively and by contraction of expiratory and inspiratory muscles. |
| Muscle |
Measure muscular twitch responses to nerve stimulation as well as demonstrating recruitment in the twitch response. Measure the decline in maximal force during a sustained contraction and examine muscle fatigue. |
| Reflexes and Reaction Times |
Investigate reflexes and reaction times in response to a variety of stimuli. |
| Respiratory Airflow and Volume |
Record and analyze respiratory signals to derive respiratory parameters, such as lung volumes and capacities. Students also perform basic tests of pulmonary function and stimulate an airway restriction. |
| Sensory Illusions |
Human sensation is the conscious perception of information from both internal and external environments. It is detected, transmitted and analyzed by the sensory neurons in the somatic nervous system and autonomic nervous system. In this laboratory, students will investigate mechanisms of sensory perception and experiment with techniques that send conflicting information to the central nervous system (CNS). |
| Sensory Physiology |
Students will make observations based on their own senses. These include sight, hearing, taste, smell and touch. Within this experiment other senses such as body awareness, balance, and heat, will also be studied. |
| The Stroop Test |
A reproduction of J.R. Stroops classic stress test. |
| Water Balance |
Students investigate how the kidneys handle fluid loads. These include water alone, isosmotic salt and monosaccharide solutions, as well as a hyperosmotic monosaccharide solution. |
