Learning based on reward prediction error (RPE) was originally proposed in the context of nondeclarative memory. We postulate that RPE may support declarative memory as well. Indeed, recent years have witnessed a number of independent empirical studies reporting effects of RPE on declarative memory. We provide a brief overview of these studies, identify emerging patterns, and discuss open issues such as the role of signed versus unsigned RPEs in declarative learning.

LONG-LASTING EFFECTS OF EARLY POSTNATAL DYSFUNCTION OF THE BRAIN MUSCARINIC CHOLINERGIC SYSTEM ON LEARNING AND MEMORY AND ADULT HIPPOCAMPAL NEUROGENESIS.
Georgian Med News
November 2024
Lab. Neurobiology of Sleep-Wakefulness Cycle, Ivane Beritashvili Center of Experimental Biomedicine, Tbilisi, Georgia.
Aim: The present investigation aimed to explore in rats the early postnatal dysfunction of the brain muscarinic cholinergic system (EPDMChS) during the most vulnerable period of postnatal development, as the possible main factor for changes in adult hippocampal neurogenesis and disorders in hippocampus-dependent spatial learning and memory.
Methods: White inbred rats (n=15 in each group) were used. EPDMCHS was produced by a new method, which includes early postnatal blocking of M1-M5 muscarinic acetylcholine receptors in the rat pups, using subcutaneous injection of Scopolamine during postnatal days 7-28.
Oral cannabidiol did not impair learning and memory in healthy adults.

Background: The effect of oral Cannabidiol (CBD) on interference during learning and memory (L&M) in healthy human volunteers has not been studied.
Method: A two-arm crossover, randomized, double-blind, placebo-controlled trial was conducted at Colorado State University Pueblo (CSU Pueblo) to evaluate the effects of 246 mg oral CBD on L&M in healthy adults. Among 57 healthy volunteers enrolled, 35 were included in the analyses.
Exploring the Impact of Declarative Learning on the Consolidation of Acquired Motor Skills Under Valence Feedback.

Implicit motor learning involves the acquisition and consolidation of motor skills without conscious awareness, influenced by various factors. Punishment and reward have been identified as significant modulators during training, impacting skill acquisition differently. Additionally, the role of a second declarative task in offline consolidation has been explored, affecting both stabilization and enhancement processes during wake and sleep periods.

Background: Psychotherapeutic memory plays an important role in maintaining therapeutic effects; however, the neural mechanisms of therapeutic metaphor promoting long-term memory were still unknown.
Objective: This study used metaphorical micro-counseling dialog scenarios to investigate the memory effect of therapeutic metaphor and correlated neural mechanisms.
Methods: At first, 31 participants read a mental distress problem, followed by a metaphorical or a literal solution, while undergoing functional magnetic resonance imaging scanning during the encoding phase.
Faster implicit motor sequence learning of new sequences compatible in terms of movement transitions.

New information that is compatible with pre-existing knowledge can be learned faster. Such schema memory effect has been reported in declarative memory and in explicit motor sequence learning (MSL). Here, we investigated if sequences of key presses that were compatible to previously trained ones, could be learned faster in an implicit MSL task.
