These tools must also match the mechanical and chemical properties of the neural tissue to avoid foreign body response and functional perturbation to local circuits. By leveraging fiber-drawing methods from the telecommun ications industry\, our group creates flexible and stretchable probes capa ble of recording and stimulation of neural activity as well as delivery of drugs and genes into the brain and spinal cord. We use these probes to in terrogate brain circuits\, such as those involved in anxiety and fear\, an d to promote recovery following spinal cord and nerve injury. Simultaneosl y\, we develop a broad range of magnetic nanotransducers that convert exte rnally applied magnetic fields into thermal\, chemical\, and mechanical si gnals\, which can then be perceived by ion channels on neurons. Since biol ogical tissues exhibit negligible magnetic permeability and low conductivi ty\, magnetic fields can penetrate deep into the body with no attenuation allowing us to apply the nanomagnetic transducers to remotely control deep brain circuits associated with reward and motivation as well as adrenal c ircuits involved in regulation of corticosterone and (nor)epinephrine rele ase.\n LOCATION:https://researchseminars.org/talk/SENSEnano/5/ END:VEVENT END:VCALENDAR
