Publisher Summary This chapter discusses neurochemical properties of locus coeruleus
(LC) neurons and the neurotransmitters that are found in neuronal inputs to and outputs from …

Noradrenergic neurons were first demonstrated in the central nervous system in 1965. The
neurons were clustered in nuclear groups throughout the brainstem and were identified as …

The locus coeruleus (LC, Lat.“blue spot”) is a heavily pigmented nucleus located in the
dorsal wall of the rostral pons in the lateral floor of the fourth ventricle (Figure 12.1). The LC …

Tract-tracing and electrophysiology studies have revealed that major inputs to the nucleus
locus coeruleus (LC) are found in two structures, the nucleus paragigantocellularis (PGi) …

(1) Electrophysiological techniques were used to investigate inputs to the locus coeruleus
(LC) in rats anesthetized with urethane. 2.(2) Neurons, histologically verified as being in the …

Locus coeruleus (LC) neurons respond to autonomic and visceral stimuli and discharge in
parallel with peripheral sympathetic nerves. The present study characterized the synaptic …

The nucleus locus coeruleus (LC) is a group of neurons situated close to the floor of the
fourth ventricle at the upper border of the pons. The cells of the rat LC are homogeneous by …

The locus coeruleus (LC) has been implicated in attentional processes related to orienting
behaviors, learning and memory, anxiety, stress, the sleep-wake cycle, and autonomic …

Discharge activity was recorded extracellularly from individual neurons of the nucleus locus
coeruleus in anesthetized squirrel monkeys. These cells exhibited long-duration (2–3 ms) …

This study quantitatively addresses the hypothesis that there is a systematic relationship
between the morphologic characteristics of locus coeruleus neurons and the particular …
