Optimizing inhibitory learning during exposure therapy

Behaviour Research and Therapy, 2008
Prevailing models of exposure therapy for phobias and anxiety disorders construe level of fear throughout exposure trials as an index of corrective learning. However, the evidence, reviewed herein, indicates that neither the degree by which fear reduces nor the ending fear level predict therapeutic outcome.

The hippocampus and inhibitory learning: a ‘Gray’ area?

Neuroscience and Biobehavioral Reviews, 2004
Gray's approach to understanding hippocampal functioning [The Neuropsychology of Anxiety: An Enquiry into the Function of the Septo-hippocampal System, 1982; The Neuropsychology of Anxiety, 2000] departs from the prevailing view of that structure as a substrate for memory.

Early inhibitory learning in the rat I. Learning and memory development

Developmental Psychobiology, 1990
AbstractThe present status of knowledge on early inhibitory learning and memory is presented. The inhibitory learning (passive avoidance) can be mastered by rat pups several hours after parturition, provided specific characteristics of the newborn organism and its neurobehavioral capabilities are respected.

Stabilization of Hebbian neural nets by inhibitory learning

Biological Cybernetics, 1984
In Hebbian neural models synaptic reinforcement occurs when the pre- and post-synaptic neurons are simultaneously active. This causes an instability toward unlimited growth of excitatory synapses. The system can be stabilized by recurrent inhibition via modifiable inhibitory synapses.

Multitrial inhibitory avoidance learning in the crab chasmagnathus

Behavioral and Neural Biology, 1992
Chasmagnathus crabs placed in the dark compartment (DC) of a double-chamber device and given electrical shocks whenever they entered or remained in the light compartment (LC), showed an LC-avoidance behavior when tested 24 h after a training session of three 30-min periods with 60-min intervals.

Inhibitory learning and memory in newborn rats

Progress in Neurobiology, 1997
Firstly, the noetic value of the ontogenetic approach to the problems of learning and memory is emphasized; then the heterochrony and uneven time course of the development of neural systems are accentuated, which fully holds for the basic cognitive functions.

Inhibitory microcircuit modules in hippocampal learning

Current Opinion in Neurobiology, 2015
It has recently become possible to investigate connectivities and roles of identified hippocampal GABAergic interneurons (INs) in behaving rodents. INs targeting distinct pyramidal neuron subcompartments are recruited dynamically at defined phases of behavior and learning.

Asymmetry between excitatory and inhibitory learning.

Journal of Experimental Psychology: Animal Learning and Cognition, 2016
Five experiments investigated how learning about the added feature in a feature-positive discrimination or feature-negative discrimination is related to the change in reinforcement rate that the feature signals. Rats were trained in a magazine-approach paradigm with 2 concurrent discriminations between A versus AX and B versus BY.

Interaction between consecutive learnings: inhibitory avoidance and habituation

Behavioral and Neural Biology, 1985
Rats were submitted to step-down inhibitory avoidance training and to habituation of a rearing response to a tone with a 2-h interval between the two tasks, and were tested for retention of both tasks on the next day. When animals were trained first in inhibitory avoidance and then in habituation, retention of the avoidance behavior was impaired.

The development of inhibitory learning and memory in hooded and albino rats

Behavioural Brain Research, 1983
A special kind of passive avoidance was elaborated which made it possible to study inhibitory conditioning in hooded (Long-Evans) and albino (Wistar) rat strains from day of birth to 10 or 11 days of age. Remaining on the safe platform for 60 sec, thus avoiding an electrified grid, for the 1st and 2nd time were the criteria.
