A15 Earthworm Smooth Muscle

View Cart “Variable Force Transducer, BSL” has been added to your cart.

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.

Dyadic Interactions Involving Parents, Children, Couples, and More | Recording from Multiple Participants Part I

Synchronizing Data from Multiple Participants
Performing a dyadic experiment takes more planning than single-participant studies. Data must be tightly synchronized, equipment must remain inobtrusive, and the experimental paradigm drives the optimal setup. Join us to learn how to record high-quality synchronized data for a wide range of applications.

What You Will Learn:
– How to synchronize data from two participants
– Recording options: ECG, EDA, EEG, fNIRS, Video
– Collaborative virtual environments
– Data analysis techniques
– Practical tips—and advice on working with children
– New ideas about your research

Live Webinar: May 20th at 8AM PT/11AM ET
