  • Scientists are excited about the potential of optogenetic methods in studying brain function and behavior.
  • optogenetic inhibition

And the fact is that it did work and we were able to trigger aggression in this region using optogenetic stimulation of ventromedial hypothalamus.

Examples

  • By contrast, although many other cortical regions also exhibited task-related activity, optogenetic inhibition in those regions had no effect on behavior.

  • The researchers used optogenetic techniques to control the activity of specific neurons with light.

  • He's got optogenetic data on a lot of people.

  • And the fact is that it did work and we were able to trigger aggression in this region using optogenetic stimulation of ventromedial hypothalamus.

  • The optogenetic vectors were then transformed by germline injection into C. elegans as described above.

optogenetic positive

Morphology

optogenetic = genetic (semi-transparent) = opto + genetic

The adjective is formed by adding the combining form 'opto-' (light-related, technical) to the common adjective 'genetic', so the sense is partially deducible but depends on a technical combining form many learners do not know.

Etymology

The word optogenetic comes from two parts: opto- meaning 'light', as in optical, and -genetic meaning 'related to genes' or 'how something is made'. So, optogenetic methods are ways to use light to control cells by changing or using their genes.
