Like other vertebrates, from goldfish to humans, rats will work in order to deliver electrical
stimulation to certain brain sites. Although the stimulation produces no evident physiological …

For rats that bar pressed for intracranial electrical stimulation in a 2-lever matching paradigm
with concurrent variable interval schedules of reward, the authors found that the time …

Behavioral economists have proposed that human preferences are constructed during their
elicitation and are thus influenced by the elicitation procedure. For example, different …

Six rats trained to press a lever to obtain rewarding electrical stimulation of the brain through
chronically implanted, lateral hypothalamic electrodes were used to estimate the rate at …

Attention deficit/hyperactivity disorder (ADHD), characterized by inappropriate levels of
activity, attention, and impulsivity, has been suggested to be caused by changes in …

Rats implanted with a monopolar electrode in the medial mesencephalon and trained to
press a lever to self-administer trains of stimulating pulses were tested under a continuous …

Although recent work on amygdalar function has concentrated on a role in fear and anxiety,
a possible role in reward processes continues to be considered. This function may occur via …

Seven self-stimulating rats with electrodes located along the medial forebrain bundle were
used to study how excitation dissipates at the end of a train of rewarding electrical pulses …
