What is neural network?
Group of nerve tracts connecting regions in the brain
Brain waves are detected with…
An electroencephalograph (EEG)
What is circuit?
Interconnected neurons that turn entering signals into output patterns that can be sent to other parts of the brain
Neurons in circuit are divided into…
Excitatory and inhibitory
What excitatory neurons do?
