14-3-3ζ is crucial for the conversion of labile short-term object recognition memory into stable long-term memory.

J Neurosci Res 2021 Jun 11. Epub 2021 Jun 11.

Laboratory of Neurobiology, CIMES, University of Malaga, Malaga, Spain.

The consolidation of new memories into long-lasting memories is multistage process characterized by distinct temporal dynamics. However, our understanding on the initial stage of transformation of labile memory of recent experience into stable memory remains elusive. Here, with the use of rats and mice overexpressing a memory enhancer called regulator of G protein signaling 14 of 414 amino acids (RGS14 ) as a tool, we show that the expression of RGS14 in male rats' perirhinal cortex (PRh), which is a brain area crucial for object recognition memory (ORM), enhanced the ORM to the extent that it caused the conversion of labile short-term ORM (ST-ORM) expected to last for 40 min into stable long-term ORM (LT-ORM) traceable after a delay of 24 hr, and that the temporal window of 40 to 60 min after object exposure not only was key for this conversion but also was the time frame when a surge in 14-3-3ζ protein was observed.

Do oral contraceptives affect young women's memory? Dopamine-dependent working memory is influenced by COMT genotype, but not time of pill ingestion.

PLoS One 2021 10;16(6):e0252807. Epub 2021 Jun 10.

Department of Psychology, University of Toronto, Toronto, Ontario, Canada.

Background: Despite the widespread use of oral contraceptives (OCs), and the well-documented influence of estrogens, notably 17β-estradiol (E2), on cognition, research relating OCs to working memory is limited and mixed. Two factors may contribute to these mixed findings: 1) pharmacokinetics of oral contraceptives, which drive fluctuations in synthetic hormone levels; and 2) genetic polymorphisms related to dopamine degradation and working memory, which interact with E2. This research investigated whether the pharmacokinetics of oral contraceptives, in concert with the single nucleotide polymorphism (Val158Met; rs4680) of the catechol-o-methyltransferase gene (COMT), influence working memory performance.

The role of attention and explicit knowledge in perceiving bistable auditory input.

Psychophysiology 2021 Jun 10:e13875. Epub 2021 Jun 10.

Department of Neuroscience, Albert Einstein College of Medicine, Bronx, NY, USA.

The auditory system frequently encounters ambiguous sound input that can be perceived in multiple ways. The current study investigated the role of explicit knowledge in modulating how sounds are represented in auditory memory for a bistable sound sequence that could be perceived equally as integrated or segregated. We hypothesized that the dominant percept of the bistable sequence would suppress representation of the alternative perceptual organization as a function of how much top-down knowledge the listener had about the structure of the sequence.
