3.26 – Memory Modulation
Inhibitory Circuits in the Basolateral Amygdala in Aversive Learning and Memory
TLDR
Targeted manipulation of GABAergic neuronal subtypes has shed light on cell-type specific functional roles in the fear learning and memory, revealing organizing principles for the operation of inhibitory circuit motifs in the BLA.
Amygdala Inhibitory Circuits and the Control of Fear Memory
Reactivations of emotional memory in the hippocampus–amygdala system during sleep
TLDR
It is found that consolidation of contextual emotional memory occurs during ripple-reactivation of hippocampus–amygdala circuits during non-REM sleep following training.
Coherent amygdalocortical theta promotes fear memory consolidation during paradoxical sleep
TLDR
It is found that overnight bidirectional changes in fear memory were selectively correlated with modifications in theta coherence between the amygdala, medial prefrontal cortex, and hippocampus during paradoxical sleep, suggesting that theta coordination in the limbic system may influence interindividual differences in memory consolidation of aversive experiences.
Interacting brain systems modulate memory consolidation
Amygdalar and Hippocampal Theta Rhythm Synchronization During Fear Memory Retrieval
The amygdalohippocampal circuit plays a pivotal role in Pavlovian fear memory. We simultaneously recorded electrical activity in the lateral amygdala (LA) and the CA1 area of the hippocampus in
Valence coding in amygdala circuits
Amygdalar and hippocampal beta rhythm synchrony during human fear memory retrieval
TLDR
Investigation of fear memory by direct intracranial recordings from 8 intractable epilepsy patients with depth electrodes in both the hippocampus and ipsilateral amygdala showed that the amygdala was involved in fear memory retrieval rather than neutral memory retrieval, while the hippocampus was involved both inFear memory retrieval andneutral memory retrieval.
Context-Dependent Encoding of Fear and Extinction Memories in a Large-Scale Network Model of the Basal Amygdala
TLDR
A large-scale neuron network model of the BA, composed of excitatory and inhibitory leaky-integrate-and-fire neurons, proposes that Mutual competition between them, mediated by feedback inhibition and driven by contextual inputs, regulates the activity in the central amygdala thereby controlling amygdala output and fear behavior.

Amygdala activity related to enhanced memory for pleasant and aversive stimuli
TLDR
It is shown that bilateral amygdala activity during memory encoding is correlated with enhanced episodic recognition memory for both pleasant and aversive visual stimuli relative to neutral stimuli, and that this relationship is specific to emotional stimuli.

TLDR
Functional neuroimaging of the amygdala during emotional processing and learning shows the importance of fibres of passage from the basal forebrain in the memory of reward.
Reactivation of hippocampal ensemble memories during sleep.
TLDR
Recordings from large ensembles of hippocampal "place cells" in three rats showed that cells that fired together when the animal occupied particular locations in the environment exhibited an increased tendency to fire together during subsequent sleep, in comparison to sleep episodes preceding the behavioral tasks.
