The following statement about artificial neurons is incorrect （）
Artificial neuron is different from artificial neuron, the latter is only a mathematical model, and artificial neuron is a kind of physical neuron which is made of a phase change material technology to simulate biological neuron.
B. A nanoscale electronic element consisting of two electrodes and a thin layer of ferroelectric material sandwiched between them. The resistance of the latter can be adjusted by a voltage pulse similar to the electrical signal of the neuron.
C. If the resistance is high, the synaptic connection will be strong. If the resistance is low, the synaptic connection will be weak.
D. Learning by artificial synapses is entirely based on this ability to adjust resistance.
As for brain computer interface, the following statement is incorrect ()
A. The system does not rely on the communication and control channels between nervous system and muscle tissue, and establishes direct communication between brain and equipment, which provides a new external communication channel for brain.
Brain computer interface (BCI) is a brain computer (computer or other device) communication system that does not depend on the normal output pathway of the brain (that is, peripheral nerves and muscles). Through this channel, the information of brain activity (such as event-related induced response, even autonomous consciousness, emotion and other information) can be directly transmitted, and then the corresponding control can be realized.
C. Direct external information (such as sound or some electrical stimulation) to the brain. This method of brain computer direct interaction provides a new idea for the research of cognitive and new intelligent systems. It is also an important hybrid intelligence technology.
D. Brain computer interface (BCI) is a kind of communication interface between brain and computer through EEG signal.
