Dual-sided Voltage-sensitive Dye Imaging of Leech Ganglia
Authors:  Yusuke Tomina and Daniel A. Wagenaar, date: 03/05/2018, view: 6742, Q&A: 0
In this protocol, we introduce an effective method for voltage-sensitive dye (VSD) loading and imaging of leech ganglia as used in Tomina and Wagenaar (2017). Dissection and dye loading procedures are the most critical steps toward successful ...

Multiplexing Thermotaxis Behavior Measurement in Caenorhabditis elegans
Authors:  Stephan Raiders, Mason Klein and Aakanksha Singhvi, date: 04/05/2022, view: 1324, Q&A: 0

Thermotaxis behaviors in C. elegans exhibit experience-dependent plasticity of thermal preference memory. This behavior can be assayed either at population level, on linear temperature gradients, or at the individual animal level, by radial

Pentylenetetrazole (PTZ)-induced Convulsion Assay to Determine GABAergic Defects in Caenorhabditis elegans
Authors:  Shruti Thapliyal and Kavita Babu, date: 09/05/2018, view: 4834, Q&A: 0
Pentylenetetrazole (PTZ) is a GABAA receptor antagonist and is used to monitor presynaptic defects in the release of the inhibitory neurotransmitter GABA. PTZ is a competitive inhibitor of GABA, and prevents binding of GABA on the GABAA ...
