Non-restraining EEG radiotelemetry is a valuable methodological approach to record in vivo long-term electroencephalograms from freely moving rodents. This detailed protocol describes stereotaxic epidural and deep intracerebral electrode placement in different brain regions in order to obtain reliable recordings of CNS rhythmicity and CNS related behavioral stages.

The video demonstrates how to use a microelectrode array (MEA) to record the electrophysiological activity of neurons derived from human induced pluripotent stem cells (hiPSCs). Electrophysiological activity from a multiwell MEA containing a neuron-astrocyte co-culture is recorded to detect action potentials from multiple neurons in the network, confirming the successful differentiation of hiPSCs into neurons.

We have developed an in vitro unfolded hippocampus which preserves CA1-CA3 array of neurons. Combined with the penetrating micro-electrode array, neural activity can be monitored in both the longitudinal and transverse orientations. This method provides advantages over hippocampal slice preparations as the propagation in the entire hippocampus can be recorded simultaneously.

The video demonstrates a method for generating excitatory cortical neurons from human-induced pluripotent stem cells (hiPSCs). Upon doxycycline induction, the hiPSCs overexpress neurogenin-2, a neural-specific transcription factor. By using specific media and co-culturing with astrocytes, this process facilitates the hiPSCs' differentiation into neurons with synaptic connections.
FAQs
Stereotaxic coordinates provide a spatial guide to the intended brain region. By combining those coordinates with gradual advancement, researchers can approach a defined location rather than relying on placement alone. This precision is important when the experiment aims to distinguish activity from individual neurons or local neural populations.
Placement is evaluated through converging signals rather than a single indicator. Signal quality can show whether the probe is receiving usable electrical activity, while tissue resistance provides information during advancement. Neuronal responses offer an additional functional check because activity detected at the target can support the intended location. Together, these observations help researchers judge placement during an experiment.
Positioning near or within a defined region can serve different experimental purposes. In recording studies, placement enables measurement of electrical activity from individual neurons or local populations. In stimulation studies, it allows controlled stimulation to be directed at selected tissue. The resulting data or responses connect electrode location with neural function.
Precision links recorded activity or stimulation responses to a defined brain region. That connection helps researchers interpret how neural tissue contributes to sensory processing, motor control, or circuit activity. Without a clearly established location, it becomes more difficult to relate an electrical signal or response to the specific neural system under investigation.
Researchers first identify the target using stereotaxic coordinates, then guide the conductive probe toward that region with gradual advancement. During positioning, they monitor signal quality, tissue resistance, or neuronal responses. These observations provide evidence that the electrode has reached a useful location and support reliable measurements from the selected neural tissue.
Precise positioning supports studies of sensory processing, motor control, neural circuits, and brain disease. It also provides a foundation for electrophysiology experiments by linking neural activity to a defined location. Beyond basic research, the approach can inform development of neural interfaces and stimulation-based therapies by showing how targeted neural tissue responds.
