A15 Earthworm Smooth Muscle

This BSL PRO lesson describes the hardware and software setup necessary to record smooth muscle from earthworm gut, in vitro.

Experimental Objectives

  1. To record the smooth muscle from an isolated segment of earthworm gut.
  2. To measure the response of the smooth muscle during the administration of different drugs.
  3. Observe the effect of temperature changes on the contractility of the smooth muscle.
  4. * Plot log-dose response curves for 5HT or EPI, ACH and ACH in ATRO.

* This objective is covered in the introductory text and recording template for BSL 4 or above only.

Combine the Newest 20 Channel EEG System with Multiple Physiology Signals

B-Alert X-Series Systems offer top of the line wireless EEG. Participants are much more comfortable in B-Alert systems, ensuring the best outcome for data quality. With a super easy setup, B-Alert X24 allows researchers to collect up to 20 channels of EEG and concurrently record physiology signals in combination with BIOPAC’s data collection systems.

• Learn new features of the B-Alert X24, including the 10/20 electrode montage system
• Discover real-time subject classifications for engagement, confusion/distraction, drowsiness, workload, and stress
• Integrate and synchronize other physiology signals including EDA, EMG, respiration, and temperature
