The amygdaloid complex is one of the structures thought to modulate brain stimulation reward (BSR) elicited from the median forebrain bundle (MFB). Previous metabolic and behavioral data from our laboratory point to the amygdaloid cortical nuclei as

The chronic mild stress (CMS) procedure was developed in rodents to target anhedonia, the core symptom of depressive melancholia. Stress exposure has been shown to induce a variety of physiological, biochemical and behavioral alterations associated w

Thresholds determined from the frequency of pulses and the current for rewarding brain stimulation were obtained from rats with lateral hypothalamic electrodes. The threshold, defined as the frequency or current corresponding to one-half the maximum

Rats implanted with lateral hypothalamic electrodes pressed a lever to obtain 0.5 s bursts of pulses under the four combinations of fixed or variable, interval or ratio, schedules of reinforcement. Along with continuous reinforcement schedules, inter

Convulsions in rats bar-pressing for electrical stimulation of the brain can interfere with the behavioural evaluation of the properties of the reward substrate. If seizure activity involves the synchronous activation of populations of neurons, then

To identify variables that underlie intuitive judgments about the sizes of groups of similar objects, we asked people to judge the relative heights of vertical bars briefly shown, two groups at a time, on a computer display. Randomly selected normal

The effect of increasing task difficulty on the threshold of rewarding, electrical brain stimulation was evaluated. Rats were trained to press a lever to obtain a brief burst of pulses to the lateral hypothalamus. The threshold was psychophysically s

In the present work, we investigated the short- and long-term effects of a single systemic injection of rat recombinant interleukin-2 on weight, food intake, and brain stimulation reward thresholds elicited from the ventral tegmental area. An inverte

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 which short delays between the response and the reward degraded

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. On a 5-s, fixed-interval schedule, the rats pressed a lever to ob
