'Brainquake' phenomenon links psychotic states to chaotic information flow
Some psychiatric disorders, particularly schizophrenia and bipolar disorder (BP), can prompt the emergence of so-called psychotic states, mental states characterized by distorted thinking patterns, altered perceptions and ...
New bioadhesive strategy can prevent fibrous encapsulation around device implants on peripheral nerves
Peripheral nerves—the network connecting the brain, spinal cord, and central nervous system to the rest of the body—transmit sensory information, control muscle movements, and regulate automatic bodily functions. Bioelectronic ...
