Electrophysiological recordings from brain slices are a direct way to probe neural function, detect pathological functional abnormalities and explore sensitivity of spontaneous and evoked electrical signal transmissions to drugs. The recordings are a valuable tool in the study of synaptic plasticity, which is thought to underlie learning, memory and some brain pathologies. Up- or down-regulation of synaptic transmission can shed light on cellular and network mechanisms of numerous CNS diseases, including Alzheimer’s disease, autism and ataxia.
This video on brain slice electrohphysiology using multi-electrode array biochips shows the sample preparation and analysis as well as data capture.
Multi-electrode arrays (MEAs) are ideal for neural studies, as they are easily multiplexed, allowing for multiple, concurrent experiments. The variety of MEA biochips allows you to customize your electrophysiological recordings and gather data from single neurons to large groups of cells.
