Objective:Create a functioning microdrive system for Thomas-style electrodes that ferrets tolerate and produces recordings in an awake ferretMicrodrive parts tracker:

2. The prototype is implanted in a ferret that has a headpost and the ferret is recorded
5
3. The design is revised at least one time after lessons learned in the first animal

Alex and Gianna need to learn to pull and grind the Thomas-style electrodes
Week of Sep 26, Oct 3
Alex, Gianna, LisandroAlex and Gianna trained (need practice)Have gone thourgh the pulling process and grinding process together and on their own.
Waiting for more fibers to come in, could use more practice.

Alex and Gianna to be trained and put on the ferret protocolASAPAlex, Gianna, Avi
11
Alex and Gianna need to receive 3-d printing training and practice printing the designWeek of Oct 3Alex, Gianna, LisandroGianna, Rico and Alex trainined on 3D printer. Need to practice printing
12
Alex and Gianna need to learn to assemble the prototype and connect the EIB boardWeek of Oct 10Alex, Gianna, LisandroAlex and Gianna have learned the steps; need to go through all of them on their ownNeed more practice shaping screws. Need to practice all the other assembly steps as well.

redesign exit of microdriveHave current metal based Jadhav design, will base new design on that
15
first cast and attempt at new shuttle/drive for discussionby Dec 8

We need to implant a prototype on a ferret
Week of Oct 17 or later
Lisandro, Rico, Alex, and GiannaHaving difficulty connecting prototype to EIB. A few more electrodes broke in the processs (2-3 electrodes left out of 8). Considering making a new drive and using gold pins for this implant. Can brainstorm some otherways of connecting to EIB while building new drive.
22
We need to evaluate the prototype in a recording setting
23
Re-design (if necessary) the microdrives to better achieve our goals in the ferret

41
Focus on the Thomas Electrode microdrives (learning how to make them and troubleshoot them)
42
 Learning how to make the Thomas electrodes
