Fine wire electrodes were surgically implanted in two regions of the brain of the snail Helix aspersa. To receive electrical stimulation of the brain, a tethered snail was required to displace the end of a rod. Self‐stimulation delivered to the parietal ganglion resulted in non‐repetition of the operant response, whereas self‐stimulation delivered to the mesocerebrum resulted in an increase in response frequency. The reinforcing effect of local extracellular stimulation of two brain zones was… Expand
Two modulatory inputs exert reciprocal reinforcing effects on synaptic input of premotor interneurons for withdrawal in terrestrial snails.
TLDR
Two modulatory inputs exert pairing-specific effects that influence the same synaptic connection in opposite directions, which may underlie the long-term up- and down-regulation of behavioral responses. Expand
Cellular mechanisms of behavioral plasticity in simple nervous systems

TLDR
Experimental studies of the cellular mechanisms of learning in the nervous systems of gastropod mollusks allow identification of a number of the principles of operation of nervous systems, which are important for descriptions of learning and memory processes. Expand
Dynamics of propagating waves in the olfactory network of a terrestrial mollusk: an electrical and optical study.
TLDR
The results of simultaneous optical and electrical measurements show that the major part of the optical signal can be interpreted as a superposition of the intracellular signals arising from the bursting and nonbursting neurons. Expand

TLDR
Functional organization of networks underlying withdrawal, feeding, and respiration in terrestrial gastropod snail Helix are described and data underlying several conceptual principles which are not widely accepted are presented. Expand
Power spectra of ongoing activity of the snail brain can discriminate odorants
To test the hypothesis that different odorants are likely to cause distinctive changes in the ongoing electrical activity of populations of olfactory cells, we investigated field potentials (FP) inExpand
The cerebral neurons of Helix aspersa during hibernation. Changes in the cytochemical detection of calmodulin, cytoskeletal components and phosphatases.
TLDR
The findings indicate that the transport of vesicles in the axons is slowed down during hibernation and that the patterns of neurotransmission and neuromodulation are also deeply modified. Expand
Ultrashort pulsed electric fields induce action potentials in neurons when applied at axon bundles
There is a constant and growing demand for new methods to treat drug-resistant neurological disease. Ultrashort pulsed electric fields are a new tool that has shown some promise for electricallyExpand
Voltage-gated membrane currents in neurons involved in odor information processing in snail procerebrum
TLDR
It is suggested that the bursting and/or non-bursting character of the PC neurons is at least partly determined by the battery of ion-channels present and their cellular and subcellular compartmentalization. Expand
Nervous system and neural maps in gastropodHelix lucorum L.
The present review summarizes the literature and provides new data concerning nervous system structure and the identification of individual neurons in the snail Helix lucorum. Information aboutExpand
The Sensitivity of the Crayfish Reward System to Mammalian Drugs of Abuse
TLDR
This work demonstrates the potential of crayfish as a model system for research into the neural mechanisms of addiction, by contributing an evolutionary, comparative context to the understanding of natural reward as an important life-sustaining process. Expand

Intracellular investigation of the increase in the spike response in command neurons for pneumostome closure, which underlies behavioral sensitization, revealed a synpatically-evoked, long-lasting depolarization. Expand
Self-Stimulation of the Brain
TLDR
It is reasonable to hope that eventually it will be possible to control the reward systems pharmacologically in cases where behavior disorders seem to result from deficits or surfeits of positive motivation. Expand
Learning in an isolated prothoracic insect ganglion
TLDR
The results showed that long-term generalized excitability changes could occur from the effects of the shock on the peripheral neuromuscular apparatus itself and showed none of the complexity seen in those with an intact isolated prothoracic ganglion. Expand

TLDR
The conclusion is that in the absence of a brain the ventral ganglia are able to associate a position of the leg with a repeated punishment by electric shock. Expand

Changes in responsiveness to food and noxious stimuli were studied in interneurons controlling feeding behavior and in putative command neurons for avoidance behavior after 10-15 paired presentationsExpand
Courtship and copulation in the terrestrial snail Helix aspersa
TLDR
There are significant differences in the mating behaviours of Helix aspersa and Helix pomatia, and dart shooting may facilitate mating by increasing behavioural synchrony. Expand
Learning of Leg Position by Headless Insects
TLDR
There is a high degree of local control of the posture and responses of the legs by the corresponding segmental ganglia; therefore not all details of the proprioceptive control of leg position need ascend to the brain. Expand
The physiological basis of memory.
TLDR
From the combination of knowledge and actions, someone can improve their skill and ability, which will lead them to live and work much better and add more knowledge to life and work better. Expand
