Enhanced Instructed Fear Learning in Delusion-Proneness

open access: yesFrontiers in Psychology, 2022
Psychosis is associated with distorted perceptions and deficient bottom-up learning such as classical fear conditioning. This has been interpreted as reflecting imprecise priors in low-level predictive coding systems. Paradoxically, overly strong beliefs,

Memory consolidation in the cerebellar cortex [PDF]

open access: yes, 2010
Several forms of learning, including classical conditioning of the eyeblink, depend upon the cerebellum. In examining mechanisms of eyeblink conditioning in rabbits, reversible inactivations of the control circuitry have begun to dissociate aspects of ...

Temporal properties of cerebellar-dependent memory consolidation [PDF]

open access: yes, 2004
Classical conditioning of the nictitating membrane response in rabbits is a well defined model of cerebellar-dependent motor memory. This memory undergoes a period of consolidation after the training session, when it is sensitive to reversible ...

Extinction phenomena: A biologic perspective on how and why psychoanalysis works

open access: yesFrontiers in Psychology, 2011
This article presents the view that much of the success of classical psychoanalysis is centrally predicated on its biological potency; focusing not on neuropsychology, but on the biology of conditioning.

APRENDIZAGEM DA EXTENSÃO DA PROBÓSCIDE EM ZANGÕES AFRICANIZADOS (APIS MELLIFERA L.) CONFINADOS

open access: yesCiência Animal Brasileira, 2015
Studies on the olfactive learning in honey bees (Apis mellifera L.) are predominantly performed with worker bees. In this study, we used the classical conditioning of proboscis extension (PER) to evaluate the effectiveness of 5 scents as conditioned ...

Pavlov's cockroach: classical conditioning of salivation in an insect. [PDF]

open access: yesPLoS ONE, 2007
Secretion of saliva to aid swallowing and digestion is an important physiological function found in many vertebrates and invertebrates. Pavlov reported classical conditioning of salivation in dogs a century ago.

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.

Application of Biological Learning Theories to Mobile Robot Avoidance and Approach Behaviors [PDF]

open access: yes, 1998
We present a neural network that learns to control approach and avoidance behaviors in a mobile robot using the mechanisms of classical and operant 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,
