 Context examples 

This time, even when marmosets were administered the treatment to make area 25 over-active, they still showed excitement and anticipation at the reward.

Marmosets are used to study brain disorders such as depression because of the similarity of the frontal lobes to those of humans.

Marmosets were given the antidepressant 24 hours ahead of the experiment.

Using marmosets, a type of non-human primate, the researchers have shown how over-activity in a specific area of the brain’s frontal lobe blunts the excitement seen when anticipating a reward and the motivation to work for that reward.

In a study involving marmosets, scientists at the University of Cambridge have identified the region of the brain that contributes to this phenomenon, and shown that the experimental antidepressant ketamine acts on this region, helping explain why this drug may prove effective at treating anhedonia.

(Marmoset study gives insights into loss of pleasure in depression, University of Cambridge)

By using PET scanning techniques to observe activity across the marmoset’s brain the researchers found that over-activity in a region of the brain known as ‘area 25’ had a knock-on effect to other brain regions, which also became more active, indicating that these were all part of brain circuity controlling anticipatory excitement.
