| Paper Presentation (5:15): Bacon & Murphey (1984) Receptive fields of cricket giant interneurons are related to their dendritic structure. J. Physiol. 352, 601-623. Describes the anatomy and mechanism of an elegant sensory integration system. | Video: Cricket Circal System (fast) | Video: Cricket Circal System (slow) |
| Keeping and Mounting Crickets (2:52): This video describes how we keep crickets, how to anaesthetize them and how to mount them for physiological recordings. With verbal instructions by Dr. Vogt. | Video: Keeping and Mounting Crickets (fast) | Video: Keeping and Mounting Crickets (slow) |
| Mounting Crickets II (0:45): This video shows a student, Kitty Fuller, mounting and preparing a cricket for physiological recording. No naration, but excellent views, some missing from above video. | Video: Keeping and Mounting Crickets (fast) | Video: Keeping and Mounting Crickets (slow) |
| Dissecting the Cricket (2:41): This video demonstrates how to dissect the cricket to reveal its abdominal ventral nerve cord, and suggests several experiments that can be performed. | Video: Dissecting the Cricket (fast) | Video: Dissecting the Cricket (slow) |
| Scenes of a Cricket (0:58): This video shows three scenes. First is a cricket, mounted, with a sensory recording shown in the background. Second is through the microscope, showing the hook electrodes under the nerve cord; the nerve cord can be seen (barely) lying across the electrodes and recordings can be heard. Third is also through the microscope ans shows sensory hairs moving on a circus with recordings heard in the background. | Video: Scenes of the Cricket (fast) | Video: Scenes of the Cricket (slow) |
| Walk around the Instruments (8:41): A tour of your work place. Presents instruments you will be using including 4 channel amplifier and pulse stimulator. Also discusses care of dissecting tools. | Video: Intrumentation Tour |
