With LabChart , students use protocols for conducting basic and advanced laboratory exercises with human subjects including: cardiovascular; respiratory; musculoskeletal; digestion; renal function and water balance; and neurophysiology.
HRV - Heart Rate Variability Analysis using LabChart
Learn to correctly perform blood pressure measurements using a stethoscope, and ADInstruments' Blood Pressure Cuff and Sphygmomanometer. Assess changes in peripheral circulation and examine the effects of cuff location.
Record electrical activity associated with eye movements and recognize common artifacts in EOG recordings. Measure and understand the significance of angular displacement measurements, smooth tracking and investigate aspects of gaze holding.
Learn how to measure skin conductance. Understand how conductance, respiratory rate, heart rate, and skin temperature change in response to stress. Use this information to complete a polygraph (lie detection test) and correctly interpret the results.
Become familiar with the basic psychophysiological measurements of skin conductance, respiratory rate, blood pressure, and electromyography. Combine these skills in the performance of a simple psychophysiology experiment.
Find the blind spot, test for colorblindness and explore the science behind some optical illusions. Determine the distribution of touch and taste receptors, and investigate thermoception. Assess joint position sense and the perception of balance.
Investigate how heart rate and finger pulse change after different exercise regimes. Study the ECG trace and the electrical signals of the heart. Determine the factors that control heart rate and blood flow to tissues before, during and after exercise.
Learn techniques behind spirometry and gas analysis in order to record respiratory variables and determine metabolic parameters. Become familiar with ADInstruments' Exercise Physiology Kit and LabChart Add-Ons for Metabolism and Spirometry.
Become familiar with techniques behind spirometry, gas analysis and electrocardiography (ECG). Record and calculate respiratory, cardiovascular and metabolic parameters. Learn about ADInstruments' Exercise Physiology System and LabChart Add-Ons designed for exercise physiology.
Investigate the effects of the diving response on heart rate and peripheral circulation in humans during simulated dives using ADInstruments' Finger Pulse Transducer, Sphygmomanometer and Respiratory Belt. Compare the physiological differences between breath-holding and diving.
Learn the positions for the standard limb leads to accurately record ECG. Identify the major components of the ECG, provide estimates of the timing of ECG components and their magnitudes. Coincidentally record heart sounds and relate these to the ECG.
Measure and analyze ECG and pulse and discuss the relationship between them. Compare differences between individuals and the effects of temperature. Discover arterial anastomoses and the connections in the blood supply of the hand.
Record and measure muscular twitch responses to nerve stimulation and observe recruitment as stimulus strength increases. Test the effect of stimulus timing on muscle contraction. Measure the decline in maximal force during a sustained contraction and examine muscle fatigue.
Recognize artifacts in an EEG signal caused by blinking and subject movement. Record and identify alpha and beta EEG rhythm, and analyze how a signal is affected by opening and shutting the eyes, mental activity and auditory stimulation.
Record EMG during voluntary muscle contractions and investigate how contractile force changes with increasing demand. Examine the activity of antagonist muscles, see the phenomenon of coactivation and calculate nerve conduction velocity.
Discover the responses of reflexes and reaction times to a variety of stimuli. Elicit and quantify a knee jerk reaction, trigger the pupillary light reflex and a withdrawal reflex, and measure reaction time in reponse to a visual cue under varying conditions.
LabChart data analysis software creates a platform for all of your recording devices to work together, allowing you to acquire biological signals from multiple sources simultaneously and apply advanced calculations and plots as your experiment unfolds.
