Contextual effects in sensorimotor adaptation adhere to associative learning rules

eLife, 2022
Traditional associative learning tasks focus on the formation of associations between salient events and arbitrary stimuli that predict those events. This is exemplified in cerebellar-dependent delay eyeblink conditioning, where arbitrary cues such as a ...

High-throughput automated methods for classical and operant conditioning of Drosophila larvae

eLife, 2022
Learning which stimuli (classical conditioning) or which actions (operant conditioning) predict rewards or punishments can improve chances of survival.

Symbolic Versus Associative Learning [PDF]

Cognitive Science, 2010
AbstractRamscar and colleagues (2010, this volume) describe the “feature‐label‐order” (FLO) effect on category learning and characterize it as a constraint on symbolic learning. I argue that FLO is neither a constraint on symbolic learning in the sense of “learning elements of a symbol system” (instead, it is an effect on nonsymbolic, association ...

Dopamine transients do not act as model-free prediction errors during associative learning

Nature Communications, 2020
Dopamine neurons are proposed to signal the reward prediction error in model-free reinforcement learning algorithms. Here, the authors show that when given during an associative learning task, optogenetic activation of dopamine neurons causes associative,

Training on multiple days results in better learning in embedded eyeblink conditioning in young human adults

npj Science of Learning
Eyeblink conditioning is mediated by similar cerebellar pathways in humans and animals and is typically investigated using delay or trace protocols. These studies show that humans can easily acquire eyeblink conditioning within a single day of training ...

Pictorial Referents Facilitate Recognition and Retrieval Speeds of Associations Between Novel Words in a Second Language (L2) and Referents

Frontiers in Communication, 2021
This study reveals associative processes for novel words in a second language (L2) and their referents. Thirty Japanese participants learned associative pairs for novel words in Chinese and pictorial referents (CP), as well as novel words in Chinese and ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
