Also known as: MEA, microelectrode arrays
Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Microelectrode arrays and microprobes have been widely utilized to measure neuronal activity, both in vitro and in vivo. The key advantage is the capability to record and stimulate neurons at multiple sites simultaneously.
Usefulness & Problems
Why this is useful
Microelectrode arrays record and stimulate neurons from multiple sites at once. The review frames them as a core platform for studying neuronal activity at single-neuron and network scales.; measuring neuronal activity; simultaneous multisite recording; simultaneous multisite stimulation; studying single-neuron and network function

Implementation Constraints
cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationoperating role: sensor
Use requires microelectrode hardware and analysis methods for interpreting extracellular signals collected at each sensor. The review also highlights ongoing integration with on-chip circuitry to improve recording quality and resolution.; signal interpretation and analysis techniques are needed because each sensor captures mixed nearby sources
They do not inherently provide the single-cell or single-channel resolution of intracellular recording. Because each sensor detects signals from multiple nearby sources, downstream analysis remains necessary.; microelectrodes detect signals from all possible sources around every sensor; lacks the single-cell or single-channel resolution of intracellular recording
