A robust way to study neuronal avalanches, i.e. scale-invariant spatio-temporal activity bursts, indicative of critical state dynamics in cortex. Avalanches emerge spontaneously in developing superficial layers of cultured cortex which allows for long-term measurements of the activity with planar integrated multi-electrode arrays (MEA) under precisely controlled conditions.

FAQs
Each electrode samples local voltage changes from nearby neurons, allowing researchers to compare when activity occurs and where it is distributed across the measured surface or tissue. Simultaneous multichannel acquisition makes network patterns visible rather than limiting analysis to a single recording site. This supports investigation of coordinated neural activity and spatially organized responses.
A micro-electrode array can support both observation and intervention, but the two functions answer different questions. Recording captures naturally occurring local voltage changes, whereas stimulation applies controlled electrical pulses to activate neural circuits. Comparing spontaneous and evoked activity can help researchers examine how a network responds to direct input, although the overview does not specify pulse parameters or stimulation protocols.
Closely positioned electrodes sample neighboring regions of a biological preparation. This arrangement helps reveal differences in activity across space while simultaneous channels preserve timing relationships among sites. The resulting dataset can show whether neural responses are localized or distributed, making array measurements useful for network-level questions involving the timing and spatial distribution of electrical activity.
Micro-electrode arrays are used with cultured cells, brain slices, and living nervous systems. These settings allow investigators to examine neural activity across different levels of organization, from developing or maintained cells to tissue circuits and intact nervous systems. The appropriate preparation depends on whether the study targets development, circuit function, sensory processing, or disease-related change.
Recordings can reveal the timing and spatial distribution of activity across a neural preparation. That information is relevant to studies of synaptic communication, neuronal development, sensory processing, and disease-related changes, because researchers can examine how electrical patterns vary across multiple sites. The same measurement capability also supports electrophysiological screening, where neural responses are evaluated across experimental conditions.
These systems combine multichannel neural recording with the ability to deliver controlled electrical stimulation. That combination is relevant to brain-computer interfaces and neural prostheses because it provides two complementary capabilities: monitoring electrical activity and activating neural circuits. In research, arrays therefore serve not only as tools for observing nervous-system function but also as platforms for developing technologies that interact with it.
