Higher-Order Conditioning and Dopamine: Charting a Path Forward

Frontiers in Behavioral Neuroscience, 2021
Higher-order conditioning involves learning causal links between multiple events, which then allows one to make novel inferences. For example, observing a correlation between two events (e.g., a neighbor wearing a particular sports jersey), later helps ...

Novel sensory preconditioning procedures identify a specific role for the hippocampus in pattern completion. [PDF]

Neurobiol Learn Mem, 2016
Successful retrieval of a memory for an entire pattern of stimulation by the presentation of a fragment of that pattern is a critical facet of memory function.

Danger Changes the Way the Mammalian Brain Stores Information About Innocuous Events: A Study of Sensory Preconditioning in Rats. [PDF]

eNeuro, 2018
The amygdala is a critical substrate for learning about cues that signal danger. Less is known about its role in processing innocuous or background information.

Nanogel-mediated delivery of oncomodulin secreted from regeneration-associated macrophages promotes sensory axon regeneration in the spinal cord [PDF]

, 2022
Preconditioning nerve injury enhances axonal regeneration of dorsal root ganglia (DRG) neurons in part by driving pro-regenerative perineuronal macrophage activation.

Reducing avoidance of learnt fear: Extinction of an imminent threat signal partly decreases costly avoidance to a distal threat signal

Journal of Experimental Psychopathology, 2023
In the interplay of fear and avoidance, not only imminent threat signals that directly predict potential threat evoke avoidance, but also distal threat signals that predict these imminent threat signals.

Emotional learning retroactively promotes memory integration through rapid neural reactivation and reorganization

eLife, 2022
Neutral events preceding emotional experiences can be better remembered, likely by assigning them as significant to guide possible use in future. Yet, the neurobiological mechanisms of how emotional learning enhances memory for past mundane events remain

Repeating patterns: Predictive processing suggests an aesthetic learning role of the basal ganglia in repetitive stereotyped behaviors

Frontiers in Psychology, 2022
Recurrent, unvarying, and seemingly purposeless patterns of action and cognition are part of normal development, but also feature prominently in several neuropsychiatric conditions.

Interactions between human orbitofrontal cortex and hippocampus support model-based inference.

PLoS Biology, 2020
Internal representations of relationships between events in the external world can be utilized to infer outcomes when direct experience is lacking. This process is thought to involve the orbitofrontal cortex (OFC) and hippocampus (HPC), but there is ...

Sensory PreConditioning: Experiment 1

, 2021
This experiment studies the possible role of stimulus – stimulus association in transferring the response from one stimulus to the other associated stimulus which was no previously linked with the response.
