Um artigo da Science publicado recentemente aponta para um eixo molecular de gradiente oposto na organização cortical dos primatas, destacando uma nova estrutura para estudar como o cérebro é organizado.

Um artigo da Science de março de 2026 relata a ativação talâmica do córtex visual em nível de sinapse única, sinalizando a continuidade do avanço rumo a medições cada vez mais finas dos circuitos cerebrais.

A new study in mice suggests psychedelic compounds make the brain prioritize stored memories over real sensory input — causing perception to be driven by internal models rather than present reality.

Researchers have found that Chlamydia pneumoniae, a widespread bacterium known for causing respiratory infections, can invade the brain and retina where it persists for years, triggering inflammation and amyloid-beta accumulation linked to Alzheimer's disease. The discovery opens new avenues for early detection through retinal imaging and potential antibiotic treatments.

Researchers from the University of Southern Denmark and Bern University Hospital found no evidence that the rat brain produces or stores DMT in serotonin-releasing neurons, undermining a decades-old hypothesis about the psychedelic compound's natural role in brain chemistry.
