In vitro reconstruction of the respiratory central pattern generator of the mollusk Lymnaea.
Most rhythmic behaviors such as respiration, locomotion, and feeding are under the control of networks of neurons in the central nervous system known as central pattern generators (CPGs). TheExpand

Reconsolidation of a Long-Term Memory in Lymnaea Requires New Protein and RNA Synthesis and the Soma of Right Pedal Dorsal 1
Reconsolidation of a long-term memory (LTM) in the snail Lymnaea stagnalis can be disrupted by cooling, an RNA synthesis blocker (actinomycin D), and by specifically ablating the soma of a cell weExpand

Nerve growth factor (NGF) induces sprouting of specific neurons of the snail, Lymnaea stagnalis.
Nerve growth factor (NGF) was examined for its ability to elicit sprouting by adult molluscan neurons. Motoneurons and interneurons (but not neurosecretory cells) from Lymnaea exhibited a sproutingExpand

Transmitter–Receptor Interactions between Growth Cones of Identified Lymnaea Neurons Determine Target Cell Selection In Vitro
In addition to their involvement in transsynaptic communication in the adult nervous system, neurotransmitters also participate in many developmental events, such as neurite initiation and outgrowth.Expand

Neuropeptide Y action in the rat hippocampal slice: site and mechanism of presynaptic inhibition
Neuropeptide Y (NPY), the most abundant peptide in mammalian CNS, has been shown to inhibit excitatory neurotransmission presynaptically at the stratum radiatum-CA1 synapse in the in vitro ratExpand

Neural Changes after Operant Conditioning of the Aerial Respiratory Behavior in Lymnaea stagnalis
In this study, we demonstrate neural changes that occurred during operant conditioning of the aerial respiratory behavior ofLymnaea stagnalis. Aerial respiration inLymnaea occurs at the waterExpand

Extinction Requires New RNA and Protein Synthesis and the Soma of the Cell Right Pedal Dorsal 1 in Lymnaea stagnalis
Lymnaea stagnalis were operantly conditioned to not perform aerial respiratory behavior. This learned response was subsequently extinguished. Here, we show that spaced extinction training is moreExpand

In Vitro Synaptogenesis between the Somata of Identified Lymnaea Neurons Requires Protein Synthesis But Not Extrinsic Growth Factors or Substrate Adhesion Molecules
Nerve growth factors, substrate and cell adhesion molecules, and protein synthesis are considered necessary for most developmental programs, including cell proliferation, migration, differentiation,Expand

Evidence for the presence, synthesis, immunoreactivity, and uptake of GABA in the nervous system of the snail Helisoma trivolvis
In the present study several techniques were employed to test the hypothesis that gamma‐aminobutyric acid (GABA) is a neurotransmitter in the central nervous system (CNS) of the pond snail HelisomaExpand

Hypoxia-induced respiratory patterned activity in Lymnaea originates at the periphery.
Respiration in Lymnaea is a hypoxia-driven rhythmic behavior, which is controlled by an identified network of central pattern generating (CPG) neurons. However, the precise site(s) (i.e., central orExpand
