Electroencephalography (EEG): electrical brain activity recorded from the scalp Strengths: convenient, safe, inexpensive Weaknesses: poor spatial resolution, require substantial training EEG Based Systems

ECoG Based Systems Electrocorticography (ECoG): electrical brain activity recorded by electrodes placed directly on the surface of the brain Strengths: less invasive than single neuron, more e f ective than EEG Weaknesses: less e f ective than single neuron, more invasive than EEG

Single Neuron Based Systems Single Neuron: series of recording electrodes placed directly into the cortical layers to record signals from individual neurons Strengths: provides highest level of control in BCI applications Weaknesses: causes neural and vascular damage, sensitive to encapsulation (short term)
