“…The ear-bar damage inflicted by the stereotaxic instrument did not affect the animals' ability to discriminate the S D . First, as in Lenzer and Frommer's (1968) study, the subjects responding for ICS reacted appropriately to the S D . Secondly, the suppression ratios for the three SW rats which were placed in the stereotaxic instrument did not differ significantly from those of the four SW rats which were unoperated (p > .20).…”

“…EXPERIMENT 2 6 This experiment used a modification of the successive discrimination procedure described by Lenzer and Frommer (1968) to assess the hypotheses described in the introduction. The principal alterations were that the discriminative stimulus (S D ) was used as the CS during fear conditioning, and that animals responding for ICS were compared with animals responding for sucrose.…”

Four experiments replicated the phenomenon that rats responding for intracranial stimulation (ICS) fail to show a conditioned emotional response following fear conditioning. Procedural variations in the experiments indicated that failure to suppress responding was not due to alteration of footshock thresholds, failure to perceive the CS, ICS-bound resistance to distraction, or disruption of associative processes by neural disorganization. The results were compatible with an incentive model of rewarding ICS.

“…Also, certain drugs, such as methamphetamine (Elder et al, 1965) and chlordiazepoxide (Trowill et al, 1969), have been found to improve partial reinforcement performance for ESB reward. Finally, it has been found that in the operant discrimination situation, which is a special subclass of the multiple partial reinforcement situation, the performance for ESB reward is just as good as, if not better than, the performance for conventional rewards (Kling & Berkley, 1968;Lenzer & Frommer, 1968, 1971Sadowsky, 1969).…”

The literature dealing with the differences between behavior maintained by rewarding brain stimulation and behavior maintained by conventional rewards is briefly reviewed. The literature is then interpreted in an associative framework, with the emphasis on specifying the stimuli that are controlling the behavior in each situation. The associative analysis shows that rewarding brain stimulation is different from conventional rewards in some fundamental respects, but that, nevertheless, the behavior maintained by rewarding brain stimulation does, in certain situations, resemble behavior maintained by conventional rewards. Brief critiques of some of the earlier theories are offered from the standpoint of the associative model.

Permanent bipolar electrodes (Lenzer & Frommer, 1968), aimed at the left septal area (coordinates: 2-3 mm anterior to bregma, 1 mm lateral to the midline of the skull, and 6.5 mm below the brain surface) and the left hypothalamic area (coordinates : 3.5 mm posterior to bregma, 1 mm lateral to the midline of the skull, and 9.5 mm below the brain surface), were implanted in each animal under pentobarbital (Nembutal) anesthesia (50 mg/kg, IP).…”

Nine rats with forebrain and hypothalamic electrodes were trained on a sensory discrimination task with S-intervals ranging from 12 to 60 sec. Their performance during a 48-h discrimination session was compared to that during a 48-h CRF session. The response measures showed that forebrain Ss performed more poorly than hypothalamic Ss during the discrimination session, even though performance of forebrain animals was better in the discrimination session than in the CRF session when time until the fust 5-min pause was considered. In the CRF session, there was no difference in performance of forebrain and hypothalamic animals, except in terms of time till fust pause. The results are discussed in terms of cumulative effects of forebrain and hypothalamic ESB.Studies dealing with behavior reinforced by rewarding electrical stimulation of the brain (ESB) show differences in behavior as a function of electrode placement. For example, in an operant situation with the animals responding on a continuous reinforcement schedule (CRF), there are differences in the short-term response rate depending on whether the electrode is in the forebrain or in the lateral hypothalamus. Olds (1958), comparing the performance of hypothalamic and forebrain Ss over the course of a 48-h session with ESB available on a CRF schedule, found that animals with forebrain electrodes responded more slowly after 4 to 8 h, whereas hypothalamic Ss responded at.a high steady rate for longer periods of time, until overcome by "physical exhaustion." aids also found that hypothalamic Ss returned, during at least 1 h of the second day of the prolonged session, to their original high rates of responding, but that forebrain animals did not return to their initial rates. One possible explanation of the data on short-term rate is that the forebrain ESB differs from the hypothalamic ESB in that it more readily produces seizures or some other kind of interfering side effect. The satiation effect would need the additional assumption that the forebrain ESB produces a cumulative or long-term increase in the frequency of these side effects. It would follow from this analysis that if the frequency or intensity of the interfering side effects could be reduced by some experimental manipulation, then the differences between the forebrain and the hypothalamic animals could be reduced. With respect to the question of short-term rate, Reid, Gibson, Gledhill, and Porter (I964) found that the administration of an *This research was supported in part by a United States Mental Health grant to Dr. G.
