Electrode Array
A configuration of multiple electrodes arranged in a specific pattern to provide targeted neural stimulation or recording.
Full Definition
An electrode array consists of multiple individual electrodes arranged in a predetermined spatial configuration to enable selective neural stimulation or high-resolution neural recording. These arrays can be linear, rectangular, or custom-shaped depending on the target anatomy and therapeutic goals. In neuromodulation applications, electrode arrays allow for precise current steering, field shaping, and optimization of therapeutic coverage while minimizing unwanted side effects. Common examples include paddle leads for spinal cord stimulation and depth electrode arrays for deep brain stimulation.
Usage
Usage note: Specify the number of electrodes/contacts when describing specific arrays.
