Sympathetic nerve activity (SNA)

Sympathetic nerve activity (SNA) is an extracellular recording of the central nervous system. SNA demonstrates “bursting” behavior, where groups of action potentials are synchronized and linked to the cardiac cycle via the arterial baroreflex.

With Kaha Sciences solutions from ADInstruments, you can record and measure SNA, and simultaneously display and analyze it against other physiological signals in real-time. The ability to record continuous data from freely moving animals across extended periods is invaluable when measuring biopotential activity as you can capture spontaneous events and physiological rhythms with accuracy, reliability and sensitivity over long experimental time courses.

Advantages of telemetry
Conscious Anesthesia affects most physiological control systems and can significantly confound your results. Telemetry allows data to be collected from conscious animals after they have recovered from surgery and enables cognitive and behavioral studies not possible under anesthesia.

Unrestrained Restraining animals induces stress which affects normal physiological functions and the data recorded. Telemetry allows data collection from animals in their home cage without the stress induced by the presence of researchers or handling.

Long-term By monitoring physiological functions over days, weeks or months, researchers can study biological rhythms and follow the development of pathology as it occurs. Within animal design strengthens the statistical power of a study and can reduce group sizes.

Advantages of Kaha Sciences Telemetry
Extensively used globally in academic and research institutions as well as biotechnology and pharmaceutical companies, Kaha systems combine high fidelity digital telemetry with patented wireless power technology to create high-quality solutions for your physiological monitoring needs. Paired with PowerLab and LabChart/LabChart Lightning, this solution sets the new standard in quality and power for implantable, wireless telemetry in rats and mice. Measure true high-fidelity signals such as ventricular and arterial pressures, sympathetic nerve activity (SNA), biopotentials (e.g. ECG, EMG & EEG), tissue oxygen, and optogenetics stimulating and recording.

In conjunction with our solutions shown below, any device with an analog output (+/- 10V) can be connected to a PowerLab data acquisition system for synchronization of the event in LabChart, including other implantable items (vascular access ports, osmotic pumps, infusion pumps). This gives you even more flexibility and the ability to integrate your data streams in one place.
