The vulnerability of productive farmland is at threat from all fronts...

Yet the interests of energy giants still weighed more heavily than Australia's most threatened industry sector.

The gold plating was done under the supervision of the experts from the Archaeological Survey of India, the minister said, adding a donor had bought the gold and got it inlaid on the walls of the sanctum sanctorum with the temple committee having no direct role in it

⤵️​ Giving the final touches to the

In more details:

  1. Adding the cone
    (painted with conductive epoxy, connected to the drive’s ground, to (try and) shield it from electrical interference, but it’s the first time I do this so I don’t know if it will work. Once on the rat, it will have a cap as well, except when plugged into the recording system.)


  2. This drive has 2 sets of tetrodes: 13 microns Nichrome wire and 17 microns Platinum-Iridium wire (testing which is best). Due to different wire material and diameter, they get gold-plated slightly differently; see this for a good plating tutorial for 12-13 um Nichrome, generously shared by John Bladon: github.com/elduvelle/ephys_tut

  3. View of the finished drive.
    I am also testing the effects of implanting the tetrodes directly in the brain during surgery, or keeping them retracted in the drive and only lower them at the end of the surgery. This is for a bilateral dorsal implant so it has two groups of tetrodes. I personally do not understand the point of not implanting directly in brain…

  4. The guide/outer cannulas and their
    Each guide cannula holds 4 tetrodes which move together, excepted 1 cannula that holds a single tetrode - to be left in the corpus callosum and used for reference. If everything works as planned. I used 27 gauge (thin walled) inner cannulas to guide the tetrodes - the smaller diameter that you can see); these do not move, only the shuttles and the tetrodes move.

Next step is implantation surgery!
