Nervous pointer dogs are catatonic, less friendly and exhibit slower heart rates than do normal dogs. Several investigators have reported that hippocampal theta (4–8 Hz) is depressed in the initial phase of an orienting response but returns to the

The 24-hr electrographic patterns (EEG, EOG, EMG) of six normal pointer dogs were recorded in a laboratory setting. Two states of sleep (slow-wave and rapid eye movement) and wakefulness (alert and drowsy) were identified. The total recording period

Much work has related limbic structure with hypothalamic function rather than with higher nervous system function. Most studies have dealt with single limbic structures rather than with several as interrelated functional systems. Upon consideration o

Electrographic patterns of 5 normal and 5 nervous pointer dogs were recorded in a laboratory setting for 24 hr. States of sleep and wakefulness were indentified and compared under baseline and experimental conditions. The independent variable for the

Four selected cases were studied following placement of 1–2 mm lesions in the septum of the cat. Degeneration of nerve fibers and terminals was observed in the olfactory peduncle, olfactory tubercle, gyrus rectus and overlying gyrus cinguli. Projec

A study of septotectal projections was undertaken to explain the presence of degenerating terminals in the inferior colliculus following electrolytic lesions in the septum of the cat. Axonal degeneration was studied in parasagittal sections stained w

Tegmental lesions produced high as well as low terminal response rates in rats trained on a fixed-interval reinforcement schedule. This diversity of effect on a measure reflecting motivational or drive level points to the complexity of reticular infl

A study of septal efferents was undertaken to acquire detailed anatomical and functional knowledge of its relations with the telencephalon, diencephalon and mesencephalon. Small lesions were placed in various parts of the septum using a stereotaxic i

The present study has shown that conditioning stimuli applied to septum, hippocampus or mamillary body result in an attenuation of the late components of potentials recorded from the anterior nuclei of the thalamus. Hippocampal and septal conditionin
