“…A participation of glial cells has been repeatedly suggested because of the ability of these cells to spatially buffer extracellular K ϩ released during periods of increased neuronal firing~Lux, Heinemann, & Dietzel, 1986!. Also, glial cells can directly respond to different neurotransmitters and neuropeptides with an increase in intracellular Ca 2ϩ concentration~e.g., Laming, 1989;Verkhratsky, Orkand, & Kettenmann, 1998!. In animals cortical DC-potential shifts during drinking and reward, as well as spontaneously occurring cortical slow potential shifts, have been found to coincide with similar shifts in various subcortical structures, where they appear to be most consistent in the hypothalamus~Aladjalova, 1964; Irwin & Rebert, 1970;Rebert & Irwin, 1969;Rowland, 1968!. Moreover, in rabbits slow DCpotential shifts were measured simultaneously in the hypothalamus and cerebral cortex, after hypothalamic stimulation.…”

As an indicator of cortical excitability, direct current (DC) potentials were recorded from thirsted subjects before, during and after drinking 400 ml of water. Self-rated thirst was distinctly reduced after drinking. Compared with control conditions in which the subjects remained thirsty, during drinking a widespread negative potential shift occurred averaging over -70 microV at Cz. At the transition from the consumatory phase to the postconsumption phase, a slow positive potential shift commenced that was most pronounced over the anterior cortex (averaging over +40 microV at Fz) and persisted for more than 3 min after drinking. Control conditions excluded muscle activity, ocular movements, and changes in body fluid and serum osmolality as possible non-neuronal sources of the DC-potential changes. The sequence of negative and positive potential shifts associated with drinking indicates a coordinate regulation of cortical excitability that may facilitate consumatory behavior and its context-dependent encoding into memory.

“…Subcortical center activity in conditioning was studied only in the ani mal brain [4][5][6], CNV at the vertex was modulated by the activities of the midline thalamus, midbrain reticular formation and perhaps the lateral hypothalamus.…”

“…This contingent negative variation (CNV) changes its amplitude and response time (RT) by psychological states such as attention, conation and motivation [9]. It might be generat ed by the action of a subcortical center, possibly in the thalamus and the midbrain [5,6]; however, there is no evidence to explain its generating mechanism or modulating effect by alteration of local activity of deep brain structure.In order to know the functional relationship between CNV at the ver tex and activity of the thalamic nucleus (1) the distribution of the thal amic slow potential shift corresponding to S1-S2-R cortical CNV; (2) the modulating effect upon CNV at the vertex by stimulation of the thalamic nuclei, and (3) the alteration of CNV at the vertex following various ther apeutic stereotactic thalamic lesions were studied. …”

In order to know the functional relationship between CNV recorded at the vertex and activity of the thalamic nucleus, the CNV at the vertex and the intrathalamic slow potentials responding to an S1-S2-R paradigm were recorded during thalamotomy under local anesthesia. It might be concluded that the activity of the medial thalamus and medial parts of the subthalamic area not only generate slow potential shifts corresponding to S1-S2-R, but also play an important role in controlling the CNV at the vertex.

“…Most early conditioning studies of the neural evoked responses have been based on the analysis of the ISI period only; the test–trial approach has not been included or used. The analysis of the ISI period has shown changes in early or late evoked neural components or changes in overall negativity or positivity (Begleiter & Platz, 1969; Chiorini, 1969; lrwin & Rebert, 1970; John, 1967; Macar & Vitton, 1980; Pinto-Hamuy, Bracchitta, & Lagarrigue, 1969; Pirch, Corbus, & Rigdon, 1985; Rebert, 1972, 1976, 1977; Rebert & lrwin, 1969). Here, the overall changes in evoked responses were studied during the omitted-UCS trials to find out whether there appeared specific time–amplitude characteristics (increases in negativity or positivity) corresponding to changes found in the multiple-unit recordings of the NM in rabbits.…”

Head movements to the conditioned stimulus (a tone CS to the left ear) were studied in 6 cats. An attempt was made to differentiate an orienting, short-latency (alpha) response from the long-latency conditioned (delayed) response. The unconditioned stimulus (UCS) was a brain stimulation to the lateral hypothalamus eliciting, in addition to orienting and approach behavior, a specific, stereotypical head movement. These behavioral characteristics of the unconditioned head movement were used for differentiating it from the conditioned short-latency head movement. Paired conditioning and randomly unpaired control sessions (5 daily sessions each) were given in balanced order to each animal. Evoked neural responses in the hippocampus and cingulate cortex were recorded simultaneously to compare the time-amplitude characteristics of evoked responses to earlier findings in multiple-unit recordings. The results supported the differentiation of the behavioral responses. The time-amplitude course of the evoked neural responses showed complex changes, appearing as an increase in the negativity during the alpha-response period (150- to 450-ms interstimulus interval [ISI]) and as an increase in the positivity during the long-latency period (700- to 1,000-ms ISI + 150- to 450-ms UCS period) on omitted-UCS (CS-alone test) trials.
