Orienting reaction in patients with night terrors.

A polygraphic study of the somatic (electromyogram), autonomic (finger plethysmogram, galvanic skin reaction, respiration, pulse), and electroencephalographic (acoustic-evoked potential and EEG-blocking reaction) components of the orienting reaction elicited by an auditory stimulus was performed in 36 patients with night terrors and in 72 matched subjects in two control groups. The study showed a significantly more intense orienting reaction in patients with night terrors than in normal subjects (Control Group I). Moreover, the orienting reaction intensity in subjects with night terrors was significantly lower than in patients with symptomatic epilepsy (Control Group II). The orienting reactions of patients with night terrors depended on the patient's age, the history of nocturnal episodes, and their clinical form, as well as on etiology.

Nervous reactivity disturbances in patients with late post-traumatic encephalic syndromes.

A polygraphic study performed on 184 patients with late post-traumatic encephalic syndromes has shown marked nervous reactivity disturbances. The disturbances, estimated by testing for the electrographic components of the orienting reflex elicited by a repetitive auditory stimulus and for their habituation, were expressed by alterations in the intensity, resistance to habituation and sequence of habituation of the somatic, autonomic and EEG components. The character and severity of these disturbances depended on the mechanism behind the syndrome-inducing cranio-cerebral trauma, site of the impact and clinical picture of the syndrome.

The orienting reflex in cats with experimental temporal lobe epilepsy.

Aluminum-induced temporal lobe epilepsy in 24 cats showed marked interictal intensification of somatic and EEG components of the orienting reaction and increase in their resistance to habituation. The greatest disturbances of the orienting response were noted in cases of bitemporal foci, of foci situated in the allocortex (hippocampus and amygdala) and of foci inducing generalized or generalized and partial seizures.

Interictal reactivity disturbances in temporal lobe epilepsy.

The electrographic study performed on 106 patients with temporal lobe epilepsy and 31 normal subjects showed marked interictal cerebral reactivity disturbances in this form of epilepsy. These disturbances, estimated by testing the orienting reflex and its habituation, were expressed, as a rule, by intensification of somatic, autonomic and electroencephalographic components of the reaction, increase in their resistance to habituation and change in the sequence in which they become habituated. The severity of reactivity disturbances depended on the localization of electroencephalographic focus, clinical form of seizures and characteristics of interictal electroencephalographic abnormalities. The most marked reactivity disturbances were noted in patients in whom the interictal foci were bitemporal, anterior or predominantly anterior (particularly left), accompanied specially by generalized or generalized + partial seizures or by interictal graphoelements of the irritative type. The reactivity disturbances were less severe in epileptics in whom the interictal foci were unitemporal (particularly right), middle, predominantly middle, posterior or associated to partial seizures. In a few patients in whom the interictal bioelectrical activity reflected a nervous hypoexcitability, the reactivity disturbances assumed the appearance of hyporeactivity. The different intensities of reactivity alterations in temporal lobe epilepsy should be related to the different capacity of the epileptogenic lesions to determine interictal changes in diffuse excitability. This capacity depends on he structures involved by the epileptic discharges, which by their morpho-functional particularities, can influence the cerebral excitability.
