Modelling the synaptic plasticity underlying habituation, sensitization and classical conditioning of the Aplysia Californica Gill Siphon withdrawal reflex
Part I of this thesis aims to familiarize the reader with some of the basics of neuroscience. It includes a simplified description of the functioning of real neurons, as well as an introduction to several of the well known neuron models, including the Hodgkin Huxley equations and the Leaky …

The Behavior-Genetic Analysis of Drosophila Melanogaster Using The Central Excitatory State
… is due to the positive correlation it has with classical conditioning in another dipteran species, the blow fly (Phormia regina). Initial experiments were performed to demonstrate and characterize CES in this species, results of which indicated that CES decays over time, is a function of sucrose …

Conditioned taste and visual aversions in chicks: effects of social transmission of acquired behavior
… toward aversive stimuli. Following aversion conditioning to a visual (red water) or taste (3% vinegar) CS, 80 chicks individually observed an audience of two conspecifics ingest the aversive CS or observed a nondrinking audience in the presence of the CS. Observation of a drinking audience …

Predator Recognition Learning in Rainbow Darters (Etheostoma Caeruleum)
… (darter alarm cues) through the process of classical conditioning. Darters in the experimental group (n=32) were trained using their alarm cues paired with cues from larval ringed salamanders (unfamiliar predator: conditioned stimulus). Darters in the control group (n=32) were trained with a …

Klassische Konditionierung posturaler Reaktionen beim Menschen, unter Einbeziehung der Kleinhirnfunktion
… due to a motor learning process. By using the classical conditioning paradigm a ramp-shaped movement, elicited by a dynamic platform, represented the unconditioned stimulus (US) and a preceeding auditory information the conditioning stimulus (CS). To modify spinal postural reflexes supraspinal …

A Comparison of Response-Contingent and Response-Independent Autoshaping Trials In Rats
… is a procedure, combining both operant conditioning and classical conditioning, used in animal training to jump-start a target behavior. Lepper and Petursdottir (2017) found that response-contingent pairings (RCP) were more effective than responseindependent pairings (RIP) in producing …

Conditioned Discrimination in the Behavior-Genetic Analysis of the Blow Fly, Phormia Regina
… that a procedure previously used to demonstrate classical conditioning in P. regina (the Nelson paradigm) may not be suitable for continued behavior-genetic analyses. A conditioned discrimination procedure is described and data are presented validating its effectiveness in demonstrating an …

High-Throughput Operant Conditioning in Drosophila Larvae
Operant conditioning is the process by which animals learn to associate their own behaviour with positive or negative outcomes, biasing future action selection in order to maximise reward and avoid punishment. It is an important strategy to ensure survival in an ever-changing environment. Although …

EFFECTS OF ACUTE THC ADMINISTRATION ON EXTINCTION OF CONDITIONED FEAR RESPONSES IN HUMANS: A FUNCTIONAL ANALYSIS OF HIGH DENSITY EEG
… extinction of conditioned fear responses. Fear conditioning was initiated using a differential classical conditioning paradigm that paired an aversive unconditioned stimulus (shock) with a signaling stimulus (CS+), whereas another stimulus served as a safety signal (CS-). Evoked potentials, …

Olfactory conditioned ejaculatory preference in the male rat : implications for the role of learning in sexual partner preferences
… failed to display this preference, implicating classical conditioning mechanisms in the development of this behavior. Examination of the time course of the development of CEP found that it develops rapidly, demonstrating the importance of early sexual experience in the determination of sexual …

Electrophysiology, agent-based modeling and inverse optimal control applications in neuroethology
… from neurophysiology, agent-based modeling, classical conditioning, Bayesian statistics and control theory to investigate foraging decisions of the Pleurobranchaea, as it integrates sensation, internal state and learning mechanisms.

A Novel Naturalistic Paradigm to Study Aerial Predator-Induced Fear
… avoidance in the rat, laboratories have utilized Classical Conditioning involving an electrical shock (unconditional stimulus) paired with a tone (conditional stimulus). While this has been proven to be a useful paradigm in understanding learned behaviors and their neural underpinnings, it cannot …

An Analysis of Associative Learning in Drosophila at the Flight Simulator
… of the single associations during conditioning in such a three term contingency has so far hardly been possible. Therefore, the operational distinction between classical conditioning as a behavior-independent learning process (CS-US associations) and operant conditioning as …

A Behavioral and Anatomical Analysis of Conditioned Taste Aversion in C57BL/6J and DBA/2J Mice
… have used a paradigm that follows the model of classical conditioning. This involves presentation of a novel tastant, such as sucrose (conditioned stimulus, CS), followed by an intraperitoneal injection of lithium chloride that induces gastric malaise (unconditioned stimulus, US), which results …

An Associative Memory Trace in the Cerebellar Cortex
Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the …

Neurobehavioral Mechanisms Supporting the Generalization of Learned Fear in Humans
… animals possess to handle this complex task is classical conditioning, wherein stimuli associated with an aversive event acquire the capacity to elicit defensive behaviors. This process helps ensure quick reactions prior to the occurrence of an imminent threat. A problem of living in a dynamic …

Circuit Mechanisms of Context-dependent Memory-based Action Selection
… (MB) (invertebrates) are thought to carry out classical conditioning (Eichler et al., 2017; Heisenberg, 2003; Suri & Schultz, 1999). This process allows animals to associate conditioned stimuli (CSs) with rewards or punishments (Pavlov, 1927). The output of these structures is thought to …

Learning to be a cocaine addict: behavioral, pharmacological, and molecular characterization of individual differences in initial learning of cocaine-environment associations
… stimuli facilitates relapse to cocaine-taking. Classical conditioning underlies the development and expression of these learned associations, and several systems implicated in both the behavioral response to cocaine and in learning and memory—e.g., serotonin2 receptors (5-HT2R), ionotropic …
