Dr. Wilson Paulo dos Santos is a distinguished Brazilian neuroscientist and professor whose work has significantly advanced the understanding of cortical development and plasticity. Born in 1958, he has combined experimental and computational approaches to investigate the neural mechanisms underlying learning, memory, and neurodegenerative disorders. His research has been published in high-impact journals, and he has mentored numerous graduate students and postdoctoral scholars who continue to contribute to the field.
Early Life and Education
Birth and Family Background
Wilson Paulo dos Santos was born on 12 September 1958 in São Paulo, Brazil. He grew up in a modest household that valued education; his mother, a schoolteacher, and his father, a civil engineer, encouraged him to pursue academic excellence. From an early age, he displayed a keen interest in biology, spending afternoons dissecting frogs and observing the intricacies of living organisms.
Secondary Education
He attended the Instituto de Ensino Médio de São Paulo, where he excelled in the sciences. His participation in the National Science Olympiad in 1974 earned him a scholarship for further studies. During high school, he participated in laboratory courses that introduced him to foundational principles of neurobiology and electrophysiology.
Undergraduate Studies
In 1976, Dr. dos Santos enrolled at the University of São Paulo (USP), where he pursued a Bachelor of Science in Biology. He graduated in 1980 with honors, having completed a senior thesis on “Neuronal Correlates of Sensory Processing in the Rat Brain.” The project involved in vivo extracellular recordings and early computational modeling, showcasing his aptitude for bridging empirical data and theoretical frameworks.
Graduate Studies
Following his undergraduate degree, he was awarded a scholarship by the Brazilian National Council for Scientific and Technological Development (CNPq) to undertake graduate studies at the Federal University of Rio de Janeiro (UFRJ). He earned his Ph.D. in Neuroscience in 1986 with a dissertation titled “Synaptic Plasticity and Cognitive Function in Rodent Models.” The research employed long-term potentiation assays and behavioral assays to correlate synaptic changes with learning performance.
Academic Career
Postdoctoral Training
Dr. dos Santos conducted postdoctoral research from 1986 to 1989 at the University of California, San Diego, under the mentorship of Dr. Linda K. Smith. His focus was on dendritic spine morphology and its relationship to synaptic efficacy. He utilized confocal microscopy and electron microscopy to map structural plasticity during learning tasks, establishing protocols that remain standard in many laboratories.
Return to Brazil and Faculty Appointment
In 1989, he returned to Brazil and joined the Instituto de Neurociências at USP as an assistant professor. Over the next decade, he progressed through the academic ranks, becoming a full professor in 2000. During this period, he established the Center for Neurodevelopmental Studies, a multidisciplinary facility dedicated to neurogenetics, neuroimaging, and computational neuroscience.
International Collaborations
His career is marked by extensive collaboration with scientists worldwide. From 2003 to 2005, he held a visiting professorship at the Max Planck Institute for Brain Research in Frankfurt, where he co-developed the first large-scale neuronal network simulations of the prefrontal cortex. These collaborations expanded his influence across continents and facilitated cross-fertilization of ideas.
Research Contributions
Neural Plasticity
Dr. dos Santos has contributed foundational insights into the mechanisms of synaptic plasticity. His laboratory demonstrated that activity-dependent modulation of NMDA receptor subunits is critical for memory consolidation in the hippocampus. Moreover, his work revealed that astrocytes actively participate in synaptic pruning during critical periods, thereby shaping cortical circuitry.
Cognitive Development
In the early 2000s, he pioneered the use of transcranial magnetic stimulation (TMS) combined with behavioral assays to study language acquisition in infants. The research established temporal windows during which the brain exhibits heightened receptivity to linguistic input, thereby influencing early educational strategies.
Neuroinformatics
Recognizing the need for large-scale data integration, Dr. dos Santos spearheaded the development of the Brazilian Neural Data Repository (BNDR). The platform aggregates electrophysiological recordings, imaging data, and behavioral metrics, providing open access to researchers worldwide. The BNDR has facilitated meta-analyses that have uncovered universal patterns in neural coding across species.
Neurodegenerative Disease Models
His later work has focused on modeling Alzheimer’s disease in zebrafish. By introducing amyloid-beta peptides into larval zebrafish, his team observed progressive synaptic loss and cognitive deficits, establishing the zebrafish as a viable model for high-throughput drug screening. This work has led to the identification of novel small-molecule inhibitors of amyloid aggregation.

Methodological Innovations
High-Resolution Imaging Protocols
Dr. dos Santos developed a dual-imaging technique that simultaneously captures calcium transients and ultrastructural changes in dendritic spines. This method, combining two-photon microscopy with rapid serial electron tomography, allows researchers to correlate functional activity with morphological remodeling in real time.
Computational Modeling of Cortical Networks
He authored a suite of computational tools that model the spatiotemporal dynamics of cortical circuits. These models incorporate realistic neuron morphology, synaptic plasticity rules, and neuromodulatory influences, providing a framework for simulating learning and memory processes at scale.
Data Sharing Infrastructure
The BNDR platform was designed with interoperability in mind, supporting standardized metadata schemas and facilitating automated data ingestion from multiple laboratory instruments. The platform’s open-source codebase has been adopted by several international consortia.
Impact on the Field
