The Machine of Forgetting is a guide to understanding how memory works and how it defines who we are. Through eleven questions, it explores a wide range of issues, from how we store memories to what makes us human, including the possibility that androids might have feelings. Published by Editorial Ariel, the new book by Dr. Rodrigo Quian Quiroga, neuroscientist at the Hospital del Mar Research Institute and ICREA professor, opens the door to the latest advances in neuroscience and artificial intelligence research, while also establishing parallels with art, philosophy, and football.

The journal Nature Mental Health has published a landmark scientific article on the prevention of depression and suicidal behaviour through an evidence-based programme designed to reduce depression and suicidal behaviour: the 4-Level Community Intervention, developed by the European Alliance Against Depression (EAAD). The EAAD approach offers a sustainable model of community-based mental health care that can be effectively adapted to a wide range of contexts, including current and future public health emergencies.

A clinical trial led by a team from the Hospital del Mar Research Institute, in collaboration with Hospital de la Santa Creu i Sant Pau, has received nearly €1.3 million in funding from Spain's Carlos III Health Institute (ISCIII), under the 2025 call of the Strategic Action in Health-Strategic Lines of Health Research. It is one of the 14 clinical trials selected. The trial is led by Dr. Ana Aldea, coordinator of the HMRIB Clinical Research Unit and Head of the Clinical Pharmacology Section at Hospital del Mar, and Dr. Rafael de la Torre, coordinator of the Integrated Pharmacology and Systems Neuroscience Research Group at the Hospital del Mar Research Institute.

Greater exposure of mothers to airborne particulate matter during pregnancy is linked to lower levels of brain myelination in newborns. This is highlighted by the first study to measure neonatal brain myelination using magnetic resonance imaging (MRI). Published in the journal Environment International, it is the result of a collaboration between Hospital del Mar and ISGlobal. The research shows that prenatal exposure to fine particles (PM2.5) is associated with slower brain maturation during the first month of life. Myelination is a key marker of brain development.

The project, conducted jointly with the Barcelonaβeta Research Center and whose results were published in The Journal of Prevention of Alzheimer's Disease, involved around one hundred volunteers who were followed for more than a year. To mark the end of five years of collaboration-beginning with the recruitment of participants-the volunteers took part in an event where the study's findings were presented. It was a way to return the results to those who made the research possible.

Immigrants develop their first psychotic episode earlier than native-born individuals-on average, three years earlier. According to the study, this is linked to accumulated trauma throughout life and the age at which migration begins. The research, conducted at Hospital del Mar in collaboration with the Hospital del Mar Research Institute and CIBERSAM, appears in the European Journal of Psychotraumatology.

A study published in Science identifies the complementary role of the main families of neurons in representing the environment. The work, coordinated by Dr. Manuel Valero, head of the Neural Computation Laboratory at the Hospital del Mar Research Institute, presents an open-access tool to analyze neuronal diversity. The tool is already freely available and can be applied to the study of other brain regions and of diseases such as Alzheimer's, epilepsy, major depression, and Down syndrome, paving the way for more specific therapeutic strategies.

This is indicated by the results of the PENSA study, a clinical trial conducted jointly by the Research Institute of Hospital del Mar and the Barcelonaβeta Brain Research Center, the research center of the Pasqual Maragall Foundation. The study concludes that combining a healthy lifestyle program with epigallocatechin gallate (EGCG), a natural compound found in green tea, could offer sustained cognitive benefits in people at high risk of developing Alzheimer's disease. Over the course of one year, around one hundred cognitively healthy volunteers, but in stages potentially prior to the onset of dementia, were monitored. They were divided into three groups. One group received only healthy lifestyle advice. The other two groups underwent a lifestyle improvement intervention program combined with either EGCG or placebo.

Researchers from the Hospital del Mar Research Institute and Yale University, in the United States, have demonstrated how the action of certain genes on precursor cells of brain formation can cause alterations linked to cortical malformations but also to the origin of neuropsychiatric diseases such as autism or bipolar disorder. The study, published in Nature Communications, is the first of its kind. It has been able to simulate the function of a list of nearly 3,000 genes linked to these pathologies during human brain development.

A study by the Hospital del Mar Research Institute, recently published in the journal PNAS, advances our understanding of how the brain makes decisions by participating in the storage of associations between different stimuli. The research has identified the importance of specific brain areas in these processes, particularly the amygdala and its relationship with parts of the cerebral cortex. This finding could lead to new therapeutic approaches for treating mental disorders such as psychosis or post-traumatic stress disorder (PTSD). The study was conducted on mice, but the researchers believe that the mechanisms involved may be similar in humans.
