The reward pathway, in the most basic sense, begins in the floor of the midbrain at the (clue: VTA), which then projects to the . This structure then projects finally to the cortex.

In terms of the nucleus accumbens, overexpression of which gene transcription factor is thought to be the main influencer of addiction?

Patients showing addictive behaviours tend to have a preserved insight; they know they are unwell.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 6 von 9

1

Dopamine release usually has the ability to update info and set new goals in the prefrontal cortex, thus having the ability to avoid compulsive repetition of a behaviour. Addictive drugs provide a potent dopamine signal which disrupts the normal dopamine learning pathway in the prefrontal cortex.

  • WAHR
  • FALSCH

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Frage 8 von 9

1

Which part of the frontal cortex concerns the following:
Emotion and reward in decision making; hyperactivity of this area during addiction behaviour represents craving

Wähle eine der folgenden:

  • Orbitofrontal Cortex

  • ‎Ventrolateral Prefrontal Cortex

  • ‎Dorsolateral Prefrontal Cortex

Erklärung

Frage 9 von 9

Wähle von der Dropdown-Liste, um den Text zu vervollständigen.

In ( non-addicted, addicted ) brains, areas such as the Anterior Cingulate Gyrus send inhibitory signals to the orbitofrontal cortex and thus the sensation of craving ( does not, does ) occur.
In ( addicted, non-addicted ) brains, the nucleus accumbens sends inhibitory signals to areas such as the Anterior Cingulate Gyrus so that the inhibitory signals are not sent to the Orbitofrontal cortex and thus the sensation of craving ( does, does not ) occur
