Q

Gene drive

A
  • CRISPR and ribozymes technologies
  • in the second generation, the whole drive copies itself onto its partner chromosome through CRISPR cuts
  • 100% of offspring
17
Q

Oxitec - Friendly Mosquitoes

A
  • genetically edited tTAV gene
  • prevents gene expression
  • binds to tetO operators, positive feedback loop
  • inhibited by tetracycline - can’t be found in the wild
18
Q

Stereotactic envenimation

A
  • GABA - inhibitory
  • β-alanine - anti-anxiety: increases brain-derived neurotrophic factor (mediator of anxiety)
  • taurine - stimulates GABA
19
Q

Educational neuroscience

A
  • neural architects
  • multisensory teaching for neuroplasticity
  • increased functional processing between temporal gyrus and amygdala
  • manipulation for reward
