Comments on Bortolon, Ricardo et al. (2011) International Worm Meeting "Spontaneous recovery from habituation to tap is interstimulus interval-dependent." (0)
Overview
Bortolon, Ricardo, & Rankin, Catharine H. (2011). Spontaneous recovery from habituation to tap is interstimulus interval-dependent presented in International Worm Meeting. Unpublished information; cite only with author permission.
Habituation is a fundamental form of learning throughout the animal kingdom but almost nothing is known about the mediating genes and proteins. The length of time between stimuli (interstimulus interval) is known to influence the rate and degree of both habituation and spontaneous recovery from habituation and whether long term memory is formed but little research has demonstrated its effect on other defining characteristics of habituation. Using a multi-worm tracker to measure habituation and recovery of both magnitude and frequency of reversals in response to tap, a 2-second interstimulus interval results in more rapid spontaneous recovery of both the magnitude and frequency of reversals from habituation than a 10-second interstimulus interval. This provides an opportunity to screen for genes which determine the mechanisms of spontaneous recovery from habituation and which mediate interstimulus-dependent differences.
