Article Correctness Is Author's Responsibility: Noradrenergic receptor modulation influences the acoustic parameters of pro-social rat ultrasonic vocalizations.

Rats produce high rates of ultrasonic vocalizations (USVs) in social situations; these vocalizations are influenced by multiple neurotransmitter systems. Norepinephrine (NE) plays a significant role in vocalization biology; however, the contribution of…

Article Correctness Is Author's Responsibility: Pigeons consistently prefer easy over harder access to food: No reversal after direct dopaminergic stimulation.

Many studies show that animals may prefer earned over free food—a phenomenon referred to as “contrafreeloading.” In rodents, dopamine—which is involved in incentive motivation and effort—facilitates the occurrence of such a preference. Here, we investi…
