With reference to emerging neurotechnology and brain-machine interface systems, consider the following statements: I. Neuromorphic hardware attempts to mimic certain computational features of biological neural systems for efficient information processing. II. Closed-loop neural systems can both interpret neural activity and provide feedback or stimulation to the nervous system. III. Electroencephalography (EEG) records electrical activity generated by the brain using sensors placed externally on the scalp. IV. Non-invasive brain-computer interface systems necessarily provide more precise neural signal acquisition than implanted neural interfaces. How many of the statements given above are correct?
