ref: -0 tags: polyimide flexible cable frontiers florida date: 10-04-2013 01:55 gmt revision:0 [head]

PMID-24062716 A highly compliant serpentine shaped polyimide interconnect for front-end strain relief in chronic neural implants.

  • Sankar V, Sanchez JC, McCumiskey E, Brown N, Taylor CR, Ehlert GJ, Sodano HA, Nishida T.
  • 20um polyimide / gold / 20um polyimide.
    • No tie layer; then again, no longevity testing either.
  • Used sacrificial aluminum coating to release polyimide.

ref: Parush-2011.01 tags: basal ganglia reinforcement learning hypothesis frontiers israel date: 01-24-2012 04:05 gmt revision:2 [1] [0] [head]

PMID-21603228[0] Dopaminergic Balance between Reward Maximization and Policy Complexity.

  • model complexity discounting is an implicit thing.
    • the basal ganglia aim at optimization of independent gain and cost functions. Unlike previously suggested single-variable maximization processes, this multi-dimensional optimization process leads naturally to a softmax-like behavioral policy
  • In order for this to work:
    • dopamine directly affects striatal excitability and thus provides a pseudo-temperature signal that modulates the tradeoff between gain and cost.
