Noradrenergic modulation of the masseteric reflex in behaving cats. I. Pharmacological studies.
The masseteric (jaw closure) reflex was utilized as a model system for assessing functional changes in central norepinephrine (NE) neurotransmission. This monosynaptic reflex was chosen because of its simple and well-defined circuitry, and because its motor component receives a dense NE innervation. Previous experiments in our laboratory described NE modulation of this reflex in the anesthetize...
متن کاملNoradrenergic modulation of the masseteric reflex in behaving cats. II. Physiological studies.
Studies in the preceding paper demonstrated that the amplitude of the masseteric reflex in behaving cats is augmented by pharmacological manipulations that increase norepinephrine (NE) tone in the motor trigeminal nucleus (MoV) through exogenous means. The present studies examine whether such a relationship also exists under physiological conditions, i.e., whether physiological increases in NE ...
متن کاملNoradrenergic modulation of sensorimotor processes in intact rats: the masseteric reflex as a model system.
The masseteric jaw closure reflex was utilized as a model system with which to gauge the functional activity of central noradrenergic neurons. This system was chosen because it is a simple monosynaptic reflex the neuronal substrate of which receives a dense noradrenergic input. The modulatory effects of norepinephrine (NE) on this response in the intact, chloral hydrate-anesthetized rat were st...
متن کاملCorrelational analysis of central noradrenergic neuronal activity and sympathetic tone in behaving cats.
The activity of the noradrenergic (NA) neurons of the feline locus coeruleus complex (LCx) were correlated with changes in peripheral sympathetic tone in behaving cats. LCx NA neurons exhibit stereotypical changes in discharge rate across behavioral states, falling virtually silent during paradoxical sleep (PS). Simultaneous recordings from LCx NA neurons and the cervical sympathetic trunk demo...
متن کاملLong-term spinal reflex studies in awake behaving mice.
The increasing availability of genetic variants of mice has facilitated studies of the roles of specific molecules in specific behaviors. The contributions of such studies could be strengthened and extended by correlation with detailed information on the patterns of motor commands throughout the course of specific behaviors in freely moving animals. Previously reported methodologies for long-te...
