Novel Optogenetics Stimulating and Recording Telemeter

Release Webinar

Kaha Sciences hosted a webinar specifically targeted at understanding the unique Kaha Sciences telemetry solution and introducing our new and novel Optogenetics/Biopotential telemeter: “Optogenetics Telemetry – shining a light on long-term optogenetics stimulation with telemetry”. Recordings of this webinar, as well as other previously held webinars, can be accessed and listened to by registering, for free, on our Knowledge Centre.

At Kaha Sciences, we are proud to have been at the forefront of innovation and improvements in small animal telemetry systems for preclinical research.  Now we have taken this innovation one step further in utilising our patented wireless power technology to develop the first fully implantable optogenetics stimulating and recording telemeter for rats  (TR58AB Optogenetics Biopotential Telemeter).

Key Features and Advantages include:

  • Unlimited power provides opportunity for long-term studies (weeks to months)
  • Unlimited power provides unrestricted stimulation patterns
  • Single implant allows biopotential recording during optogenetics stimulation
  • Fully implantable device – normal unrestricted animal behaviour and movement with no tethers
  • Fully implantable device – reduces probability of infection at cable exit sites
  • Fully implanted device – reduction in cost of maintenance and replacement of tethers
  • Software controlled, user defined stimulation parameters
  • Easily integrates into existing Kaha Sciences installations (minor updates required)
  • Access to all the other beneficial aspects of the Kaha Sciences rat telemetry system, including Cohousing, dual implantation and recording away from the SmartPad.
  • Sampling data at 2 kHz, ensuring high data quality
  • 40 selectable Independent transmission frequencies

Optogenetics is a relatively recent technique which uses light to precisely control neuronal cells that have been transfected with a specific channelrhodopsin.  Compared to conventional electrical stimulation, optogenetics reduces the activation of neighbouring cells ensuring that stimulation is highly targeted and results in specific physiological and behavioural effects.  Current tethered or headmounted systems have disadvantages including:

  • increased susceptibility to infection
  • impacts normal physiology and behaviour
  • restriction of experimental duration and protocols due to restraint and/or limited battery-life
  • additional costs of tether maintenance and replacement.
