Serotonin and Norepinephrine in Latent Inhibition.
… in behavior. Depletions of the neurotransmitters norepinephrine and serotonin have been demonstrated to alter associative processes in the rat. This study investigated the effect of selective depletions of norepinephrine and serotonin on the formation of inhibitory associations. It was found that …

The role of locus coeruleus norepinephrine in reinforcement learning
Norepinephrine (NE) is one of the four main neuromodulators in the brain, exerting widespread influence over almost all cortical and subcortical brain regions, with the exception of the striatum. The locus coeruleus (LC) is a small brainstem nucleus, and the primary source of NE in the brain. LC-NE …

The Role of Norepinephrine in a Learning-Relevant Neural System
There is much evidence to suggest that norepinephrine (NE) is an important factor in many physiological and psychological functions. However, clear demonstrations of the behavioral relevance of the effects NE has on the activity of single neurons have been lacking. In this experiment, the neural …

Dopamine-Beta-Hydroxylase and Norepinephrine Transporter Immunoreactivity in Rat Taste Buds
… of neurotransmitters modulating taste response, norepinephrine (NE) may be the least understood. Although the physiological role of NE has been tested, it is still unclear whether the rat taste bud may serve as an endogenous source of neurotransmitter or if it must be taken up from outside the …

Evaluation of pressor sentivity to norepinephrine infusion in dogs with iatrogenic hyperadrenocorticism
… during infusions of increasing dose rates of norepinephrine. Animals: Eight dogs with I-HAC induced by administration of oral hydrocortisone at a mean dose of 3.3 mg/kg PO TID for 42-49 days and 8 control dogs which received empty gelatin capsules PO TID for 42-49 days. Procedure: Systolic, …

The role of norepinephrine in arousal and attention: a human and rat study
Background The locus coeruleus-norepinephrine (LC-NE) system is known to play an integral role in attention and arousal. The LC fires both tonically and phasically. We propose that tonic firing of the LC-NE system needs to be maintained in a critical range for phasic activity of the LCNE system to …

DEVELOPMENT OF ALZHEIMER'S-LIKE PATHOLOGY IN NON-HUMAN PRIMATES WITH REDUCED LEVELS OF NOREPINEPHRINE
Synthesis of the norepinephrine distributed to sub-cortical and cortical brain regions occurs in the locus coeruleus. Impaired function results in reduced availability of norepinephrine. Locus coeruleus degeneration is a well-documented feature of Alzheimer's disease; however, the role of …

Computational Ligand-Based CNS Therapeutic Design: The Search for Novel-Scaffold Norepinephrine Transporter Inhibitors
… the serotonin transporter (SERT or 5-HTT), norepinephrine transporter (NET), and dopamine transporter (DAT), serve as the principal targets for antidepressant drugs, such as SSRIs (selective serotonin reuptake inhibitors), NRIs (norepinephrine reuptake inhibitors) and TCAs (tricyclic …

Locus-coeruleus norepinephrine system function in a developmental animal model of schizophrenia: the socially isolated rat
… performed on projections of the locus coeruleus norepinephrine system, known to be involved in attentional function, as research on this system is surprisingly sparse. The secondary aim of the study was to address the negative symptoms of schizophrenia using ultrasonic vocalisation recording to …
