Consistent with an existing computational model of hippocampal function, using real-time feedback to drive artificial memories at the trough of the hippocampal theta rhythm improves apparent recall.
The abstract framework of rate-distortion theory can be realized by a neural population coding model to reproduce key and previously unexplained regularities of human visual working memory.
Behavioral analyses and an optogenetic approach reveal an existence of GR-mediated metaplasticity in the LA and its link with adaptive fear response to auditory cues in a stressful condition.
Population response magnitude predicts how well an image will be remembered, in both monkey inferotemporal cortex and neural networks trained to categorize objects.
Cerebellar-periaqueductal grey interactions contribute to fear-conditioned processes and, as such, provide a novel target for treating psychological conditions including post-traumatic stress disorder.
Output neurons in the mushroom body of the fruit fly brain encode the positive or negative survival value of stimuli, enabling insects to choose adaptive approach and avoidance behaviors through associative learning.

A critical regulator of inhibitory neurotransmitter signaling in the hippocampus has been identified in experiments on mice and been shown to play essential role in synaptic plasticity and memory.
Sleep-encoded vocabulary influences awake decision-making 36 hr later, particularly when targeting the vocabulary to slow-wave troughs, which suggests that unconscious episodic memory formation during deep sleep is possible.
Constitutive deficiency of AP2γ transcription factor impairs hippocampal glutamatergic neurogenesis and induces alterations on limbic-cortical connectivity that contribute to anxiety-like behavior and cumulative memory deficits in mice from juvenile to adult periods.
