Effects of local anesthesia of the cerebellum on classical fear conditioning in goldfish

open access: yesBehavioral and Brain Functions, 2010
Background Besides the amygdala, of which emotion roles have been intensively studied, the cerebellum has also been demonstrated to play a critical role in simple classical fear conditioning in both mammals and fishes.

Temporal Factors Modulate Haloperidol-Induced Conditioned Catalepsy

open access: yesFrontiers in Behavioral Neuroscience, 2021
Repeated pairings of a neutral context and the effects of haloperidol give rise to conditioned catalepsy when the context is subsequently presented in a drug-free test.

Avoidant symptoms in PTSD predict fear circuit activation during multimodal fear extinction [PDF]

open access: yes, 2013
Convergent evidence suggests that individuals with posttraumatic stress disorder (PTSD) exhibit exaggerated avoidance behaviors as well as abnormalities in Pavlonian fear conditioning.

Roles of octopaminergic and dopaminergic neurons in appetitive and aversive memory recall in an insect

open access: yesBMC Biology, 2009
Background In insect classical conditioning, octopamine (the invertebrate counterpart of noradrenaline) or dopamine has been suggested to mediate reinforcing properties of appetitive or aversive unconditioned stimulus, respectively. However, the roles of

Role of the motor cortex in the generation of classically conditioned eyelid and vibrissae responses

open access: yesScientific Reports, 2021
The eyelid motor system has been used for years as an experimental model for studying the neuronal mechanisms underlying motor and cognitive learning, mainly with classical conditioning procedures. Nonetheless, it is not known yet which brain structures,

An Artificial Synaptic Plasticity Mechanism for Classical Conditioning with Neural Networks [PDF]

open access: yes, 2014
We present an artificial synaptic plasticity (ASP) mechanism that allows artificial systems to make associations between environmental stimuli and learn new skills at runtime. ASP builds on the classical neural network for simulating associative learning,

Asymptotics of Randomly Weighted u- and v-statistics: Application to Bootstrap [PDF]

open access: yes, 2012
This paper is mainly concerned with asymptotic studies of weighted bootstrap for u- and v-statistics. We derive the consistency of the weighted bootstrap u- and v-statistics, based on i.i.d. and non i.i.d.

Trace eyeblink conditioning is impaired in α7 but not in β2 nicotinic acetylcholine receptor knock-out mice

open access: yesFrontiers in Behavioral Neuroscience, 2010
Nicotinic acetylcholine receptors (nAChRs) are essentially involved in learning and memory. A neurobiologically and behaviorally well-characterized measure of learning and memory, eyeblink classical conditioning, is sensitive to disruptions in ...

Calibrating Generative Models: The Probabilistic Chomsky-Schützenberger Hierarchy [PDF]

open access: yes, 2020
A probabilistic Chomsky–Schützenberger hierarchy of grammars is introduced and studied, with the aim of understanding the expressive power of generative models.

The Search for Invertebrate Consciousness [PDF]

open access: yes, 2020
There is no agreement on whether any invertebrates are conscious and no agreement on a methodology that could settle the issue. How can the debate move forward?
