Competition for sucrose-pellets in triads of male Wistar rats: disinhibitory effect of individual housing in poor-performing rats.
Within triads of male Wistar rats, some animals almost completely abstain from competition for palatable sucrose-pellets (so-called poor-performing rats). Individual housing temporarily helped these rats to behave more competitively. Such changes in the poor-performing rats' competition-scores are discussed in relation to previously described, isolation-induced alterations in serotonergic and noradrenergic neurotransmission.
