Learning and memory are fundamental processes for an organism's normal physiological function. Learning can occur at any stage of the organism's physiological development. Imprinted memories formed during the early developmental stage, unlike learning and memory, can last a lifetime.

Nanoplastic contamination is an emerging environmental concern worldwide. In particular, sulfate anionic surfactants often appear along with nanosized plastic particles in personal care products, suggesting that sulfate-modified nanosized polystyrene (S-NP) may occur, remain, and spread into the environment. However, whether S-NP adversely affects learning and memory is unknown.

Insulin/insulin-like growth factor (IGF) receptor signaling (IIS) supports context-dependent learning in vertebrates and invertebrates. Here, we identify cell-specific mechanisms of IIS that integrate sensory information with food context to drive synaptic plasticity and learning. In the nematode Caenorhabditis elegans, pairing food deprivation with an odor such as butanone suppresses attraction to that odor.

Proper management of memories by forgetting and retrieval is essential for animals to adapt their behavior to changing environments. To elucidate the mechanisms underlying forgetting, we use olfactory learning to an attractive odorant, diacetyl, in hermaphrodites as a model. In this learning paradigm, the TIR-1/JNK-1 pathway in AWC sensory neurons accelerates forgetting of the olfactory memory, which is stored as a sensory memory trace in AWA sensory neurons.

Article Synopsis
- Developmental experiences are crucial in shaping the physiology and behavior of adult organisms, as seen in the study of Caenorhabditis elegans.
- Postdauer adults show distinct gene expression changes, particularly in chemoreceptor genes, which may influence their behavior.
- The study reveals that postdauer adults have an increased attraction to specific food-related odors, linked to the upregulation of the diacetyl receptor ODR-10 in olfactory neurons, suggesting a mechanism for how past experiences affect current behavioral preferences.
