“…A recent analysis of habituation of the acoustic startle response in rats supports this view (Groves, Wilson, & Boyle, 1974) . Finally , it is of interest that we have again confirmed that both increments and decrements in neuronal activity result from repetitive sensory stimulation, as reported previously for plasticity of neuronal and behavioral responses in a wide variety of organisms and systems including both vertebrates (Bell et al, 1964;Buchwald, Halas, & Schramm, 1965;Buchwald & Humphrey, 1973 ;Groves & Thompson , 1970;Hinde, 1970;Horn & Hill, 1966 ;Pearson & Wenkstern, 1972;Segundo & Bell, 1970;Scheibel & Scheibel, 1965;Thompson & Spencer, 1966) and invertebrates (e.g., Carew et aI, 1971;Eisenstein & Peretz, 1973 ;Lahue & Corning, 1973 ;Rowell, 1970). Thus, there is widespread evidence for the view that plasticity of response to repetitive stimulation results from the interaction of both incremental and decremental processes.…”

Plasticity of reticular formation neuronal responses to repetitive sensory stimulation was studied in locally anesthetized paralyzed rats. Eighty-four percent of neuronal responses studied (n = 80) showed either decrement, increment, or increment followed by decrement in responses to repetitive sensory stimulation. Effects of stimulus parameters on neuronal plasticity were similar to effects reported for plasticity of behavioral and neuronal responses in other organisms. Spontaneous activity ,;\sually decreased as a result of stimulus repetition, although exceptions were noted. Latency from stimulus onset to first spike discharge increased during the course of stimulus repetition. Dishabituation was evident for many of the units tested, particularly for strong extra stimuli such as tail pinches. No differential location of neurons within the reticular core with respect to characteristics of plasticity was observed.

“…This suggests that state has been activated and some residual influence upon responsivity is seen even after habituation. Previous experi- ments with dorsal nerve responses have also suggested a competition between incremental and decremental processes in Limulus (Lahue & Corning, 1973). Furthermore, as is the case here, rate of habituation, presence of responsivity above 100%, and enhanced sensitivity to dishabituation stimuli have all been considered as characteristic of this competition.…”

“…The rate of habituation at the different frequencies rather closely paralleled the decrement seen in dorsal nerve recordings, although less habituation was observed in the latter with a 60-sec ITI. The possibility of demonstrating response sensitization at higher frequencies of stimulation (e.g., 1-sec ITI), as was observed in dorsal nerve recordings (Lahue & Corning, 1973), was precluded by the duration of the telson response, which approached 5 sec. True dishabituation was demonstrated in that the response to air on the 21st trial exceeded that prior to the dishabituation stimulus.…”

“…The large central nervous system permits easy dissection and location of specific ganglia; microelectrode, perfusion, and lesion techniques are readily applied to any portion of the nervous system in acute preparations (Corning, Lahue, & Von Burg, 1971;Von Burg & Corning, 1970; and methods for chronic monitoring in relatively unrestrained animals have also been developed (Adolph, 1971;Corning, Feinstein, & Haight, 1965). Evidence for habituation has been established at the neuronal level , and the neurophysiological and biochemical mechanisms of this form of plasticity are beginning to be understood (Lahue, 1974;Lahue & Corning, 1973). The 1061 basic paradigm in these neuronal investigations was to use a puff of air or a drop of water applied to the gills as a stimulus and to record the responses of units in the dorsal nerves of the abdominal ganglia.…”

Muscle correlates of reflex telson movement were recorded in intact Limulus (horseshoe crab) preparations with chronically implanted microelectrodes. Muscle activity habituated during repetitive tactile stimulation of the gills with puffs of air. Dishabituation was also observed, as were inverse relationships between the frequency and intensity of stimulation and the rate of response decrement. These findings closely paralleled those obtained during central recordings in acute dissected preparations, as did the demonstration under certain stimulation conditions of an initial incremental phase of responsivity. Although initial levels of responsivity recovered after 1 hr without stimulation, potentiation of habituation was observable after 2 hr. Both of these times greatly exceeded those previously observed in acute preparations. No generalization to a spatial displacement of the stimulus was obtained, although a visually elicited telson reflex had been shown to demonstrate a cross-optic generalization. Aspects of the comparative strategy and the adaptive value of telson reflex habituation in Limulus were briefly considered.The "simple system" strategy, which relies upon surgery or phylogeny to provide preparations of limited complexity, is resulting in considerable information with respect to learning mechanisms (Corning, Dyal, & Willows, 1973a, 1973b, 1974Kandel & Spencer, 1968). However, as potential substrates of behavior are uncovered, it is becoming increasingly clear that a more conservative approach toward comparative generalizations is required, since many similar processes observed across species are found to be subserved by dissimilar mechanisms (Corning & Lahue, 1972;. The establishment of comparative similarities and dissimilarities requires a "polythetic" strategy, which compares and classifies systems or processes according to multiple criteria and at many levels of biological organization (Corning, Dyal, & Lahue, in press;Lahue & Corning, 1974;Sneath & Sokal, 1973).If multiple criteria and levels are required for sounder comparative analyses, then a critical consideration involves the selection

“…Groves and Thompson cite a number of vertebrate preparations in which these two processes are observed. There is good evidence for these two processes of habituation in an arthropod as well as the possibility of a third, modulatory function (Lahue and Corning, 1973a). Dorsal nerve efferents in Limulus were activated by several different tactile stimulation frequencies (see pp.…”
