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.

Clinically relevant animal models of intracerebral hemorrhage (ICH) are needed to extend our knowledge of hemorrhagic stroke and to examine novel therapeutic strategies. In this study, we describe and evaluate two ICH models that implement unilateral injections of either autologous whole blood or bacterial collagenase into the basal ganglia (corpus striatum) of mice.

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

The autologous blood injection model of intracerebral hemorrhage in mice described in this protocol uses the double injection technique to minimize risk of blood reflux up the needle track, no anticoagulants in the pumping system, and eliminates all dead space and expandable tubing in the system.
FAQs
Conductive contacts detect voltage changes produced by nearby neuronal activity. Because the contacts sit within brain tissue, recorded signals can be associated with particular neural circuits and structures rather than treated as activity from the brain as a whole. This local electrical access gives investigators fine-grained temporal and spatial information for examining neural signaling and brain function.
Controlled electrical pulses provide a way to modulate selected brain regions, complementing the recording function of the same general device class. Researchers or clinicians can therefore examine neural activity and also influence circuit function under experimental or clinical conditions. This dual capability supports studies of brain function and targeted approaches such as deep brain stimulation.
Intracerebral electrodes are used alongside noninvasive methods because they provide direct access to electrical activity within specific brain regions. Their high spatial and temporal resolution can connect signals with defined structures and rapid neural events, while noninvasive approaches offer complementary measurements. Together, these approaches broaden investigation of circuits, behavior, and brain function.
By associating electrical activity with specific brain structures, investigators can relate circuit signaling to observed behavior and to mechanisms involved in brain disorders. This structure-function link is central to neuroscience because it moves analysis beyond a general measure of brain activity. It can also guide targeted investigation of regions involved in disorders and potential therapeutic strategies.
In epilepsy research and clinical evaluation, recordings from implanted contacts help identify brain structures associated with epilepsy-related electrical activity. Their location within the brain supports precise comparison of signals across neural regions, allowing investigators to connect electrical patterns with anatomical sites. This information contributes to epilepsy localization and can clarify the circuits involved in the disorder.
Electrical pulses are applied in clinical contexts when the goal is to modulate a selected brain region rather than only record its activity. Deep brain stimulation is the clearest application identified in the source material: controlled stimulation targets specific neural circuitry. The approach illustrates how intracerebral electrodes can connect circuit-level neuroscience with targeted therapeutic intervention for brain disorders.
Beyond epilepsy localization and deep brain stimulation, these electrodes support research on neural interfaces, brain disorders, and targeted therapies. Their value comes from combining anatomical specificity with electrical access, so investigators can study how circuits operate, how disease alters them, and how selected regions might be influenced. These applications place the technique at the intersection of basic neuroscience and clinical research.
