Movable Probe Testbed

• Description and diagram of Bradleys setup and
  how were using it.

2
Movable Probes The Hardware

• Last time Working on motorizing the CCMD
• Constraints
• Removable
• Not designed with motors in mind
• Completed with lessons learned

3
Movable Probes The Hardware

• The Goal- Chronic movable array of electrodes
• Full project must wait for MEMS development
• Majority of space taken up by motors and motor
  support
• Until MEMS Make the motors removable
• Three phases to maximize scientific gain and
  engineering development along the way

Movable Probes The Hardware

• Phase 1 Two motor micro-drive that fits inside
  the headcap
• Power, control and data lines will be attached at
  the start of each session
• Could possibly track the same cell for long
  periods of time. Useful in studies on learning
  and plasticity.

Movable Probes The Hardware

• Phase 2 Two motor micro-drive that fits inside
  the headcap with detachable motor assembly.
• Motors will be attached at the start of each
  recording session. Electrodes will remain in
  position chronically
• Develop ability to remove and attach motors on a
  small scale

Movable Probes The Hardware

• Phase 3 12-16 motor micro-drive with removable
  motor assembly
• Consistent recordings of multiple cells

7
Movable Probes The Hardware

• Phase 1 Design Progress
