Brain

Biopac Science Lab comes with four lessons focused on brain activity:

  • Lesson 5 — EEG I Electroencephalography: Brain Rhythms
    • Lesson 5 introduces electroencephalographic (EEG) recording techniques. Students record EEG from the occipital lobe while performing a number of different tasks to demonstrate how the brain’s electrical activity varies depending on the task. The software filters the raw EEG signal to separate and display alpha, beta, delta, and theta rhythms.
  • Lesson 6 — EEG II Electroencephalography: Alpha Rhythms (in the Occipital Lobe)
    • In Lesson 6, students will discover how the brain constantly receives sensory input and integrates the information before processing it. Students record EEG data from the occipital lobe while performing a number of tasks. The system records and displays the raw EEG together with the alpha-wave and alpha-RMS activity. Students compare baseline EEG with the data recorded during the different tasks.
  • Lesson 8 — EOG 1 Electrooculogram
    • In lesson 8, students record electrooculograms (EOG) for horizontal eye movement and observe eye fixation and tracking. Students perform a number of tasks that allow them to record the duration of saccades and fixation. Students also record spatial position of eye movements.
  • Lesson 11 — Reaction Time Fixed and Pseudo-random Intervals
    •  Lesson 11 demonstrates the effect of learning and physiological processes on reaction times. Students hear two presentation schedules of clicks through a set of headphones. With electrodes in place to record the activity of the extensor digitorum (the primary muscle used to lift a finger), the Subject lifts finger as quickly as possible after hearing a click. Students then perform a statistical analysis of the results, including: group mean, variance, and standard deviation.
    • Note: Use the stimulus accessories for the reaction time lesson.
