Brain-Computer Interfaces (BCIs) represent a rapidly growing investment sector in neurotechnology, with particular relevance for neurodegenerative diseases. The technology enables direct communication between the brain and external devices, offering transformative applications for patients with ALS, locked-in syndrome, and other conditions causing severe motor impairment. This investment landscape analyzes the current BCI technology ecosystem, key players, funding trends, clinical applications, and strategic opportunities for investors and researchers in the neurodegeneration space.
