The plastic brain: neurotoxicity of micro- and nanoplastics
This review examines the emerging evidence that micro- and nanoplastics can reach the brain in both aquatic animals and mammals, potentially causing neurotoxic effects.

Assessment of oxidative stress, neurotoxicity, genotoxicity and prey-predator interactions in freshwater snails exposed to microplastics
This conference abstract investigates oxidative stress, nerve damage, DNA damage, and changes in predator-prey behavior in freshwater snails exposed to microplastics, pointing to a broad range of harmful biological effects. Understanding these impacts in aquatic invertebrates matters because they occupy important ecological roles and their exposure to microplastics can have cascading effects through food webs.

The study highlights the importance of monitoring food contamination to protect neurological health.
Micro- and nanoplastics in neurological dysfunction
This review examines growing evidence that micro- and nanoplastic particles can interfere with the nervous system across multiple species, including humans. Researchers found that plastic particles may disrupt cellular metabolism, affect brain development, and increase vulnerability to neurodevelopmental disorders and neurodegeneration. The authors highlight significant knowledge gaps that need to be addressed to understand the long-term neurological impacts of plastic particle exposure.
The ecotoxicological impact of microplastics on freshwater invertebrates
This review summarizes the ecotoxicological effects of microplastics on freshwater invertebrates, finding evidence of harm including reduced feeding, growth, and reproduction across multiple species. Because invertebrates are key links in food webs, these effects could have broader consequences for freshwater ecosystems.
From environment to brain: the role of microplastics in neurobehavioral disorders

Microplastics: impact on marine animals and their remediation strategies
This review examines the presence and impact of microplastics on marine animals including fish, mollusks, echinoderms, and crustaceans. Researchers found that marine animals ingest microplastics either directly through filter feeding or indirectly through contaminated prey, leading to tissue damage, metabolic disorders, and oxidative stress. The chapter also evaluates remediation strategies including physicochemical methods and microbe-based degradation technologies.
Environmental exposure pathways of microplastics and their toxic effects on ecosystems and the nervous system
This review examines the environmental pathways by which microplastics enter the human body through ingestion, inhalation, and skin contact, with a particular focus on their effects on the nervous system.

Neurotoxicity induced by aged microplastics from plastic bowls: Abnormal neurotransmission in Caenorhabditis elegans
Researchers found that microplastics released from aged plastic bowls caused nerve damage in the roundworm C. elegans at environmentally realistic concentrations. The aged microplastics disrupted neurotransmitter systems including dopamine and serotonin, leading to impaired movement. This study is concerning because it shows that everyday plastic items we use for food can release microplastics that have neurotoxic effects.
Microplastics/nanoplastics and neurological health: An overview of neurological defects and mechanisms
This review summarizes evidence that micro and nanoplastics can harm the nervous system, causing developmental abnormalities, brain cell death, neurological inflammation, and potentially contributing to neurodegenerative diseases. Animal studies show that these tiny plastics can cross the blood-brain barrier and accumulate in brain tissue, where they trigger oxidative stress and disrupt normal brain function. While direct evidence in humans is still limited, the findings suggest that chronic microplastic exposure could be a risk factor for neurological health problems.
Effect of hypoxia and reoxygenation on the nervous system of the Mediterranean mussel Mytilus galloprovincialis
Despite its title referencing neuroplasticity in marine mussels, this paper studies how the Mediterranean mussel's nervous system adapts to cycles of low oxygen and re-oxygenation — not microplastic pollution. It examines molecular and cellular mechanisms of hypoxia tolerance in marine bivalves and is not relevant to microplastics or human health.
