A brain-computer interface (BCI) contains a set of sensors and a signal processing section that directly converts brain activities into a series of communication or controlling signals. They have three main tasks: collect the brain signals, translate them, and send output commands to a connected device. Brain signals are multiplied in a matrix ...
At synapses, an electrical impulse triggers the release of a chemical messenger, called neurotransmitter, from the ending of one neuron (a nerve terminal). This neurotransmitter passively diffuses across the space to the next neuron where it binds to specialized receptor proteins.
Sep 29, 2021 · Four contributions in this SI proposed new methods for the analysis of brain signals and data from neuroscience studies. Noticeably, all of them are based on artificial intelligence (AI) approaches, which are clearly the new frontier for brain signal processing.
Nov 30, 2022 · When signals arrive at a brain region, they engage local neural circuits — interconnected neurons that turn entering signals into output patterns that can be sent to other parts of the brain. The cerebral cortex is packed with neural circuits.
