Summary
The central noradrenergic system regulates stress responses; its overactivity is linked to functional psychoses like anxiety and schizophrenia, while underactivity causes apathy.
Area of Science:
- Neuroscience
- Psychiatry
Context:
- The central noradrenergic system, analogous to the peripheral system, is crucial for stress and fight/flight responses.
- Dysregulation of this system is implicated in various mental health conditions.
Purpose:
- To review the function and dysfunction of the central noradrenergic system.
- To explore its implications for understanding functional psychosis pathophysiology.
Summary:
- System overactivity leads to hyperarousal (insomnia, anxiety, paranoia), while underactivity results in low arousal (apathy, hypersomnia).
- Excess stress can cause noradrenergic system dysfunction, contributing to conditions like anxiety disorders, schizophrenia, mood disorders, and BPSD.
- Pharmacological interventions targeting noradrenaline activity influence hyperarousal and require careful consideration in treatment.
Impact:
- Understanding central noradrenergic system pathophysiology offers insights into arousal mechanisms.
- This knowledge can advance the diagnosis and treatment strategies for functional psychoses.

01:27Adrenergic Neurons: Neurotransmission
Postganglionic sympathetic fibers (except those supplying the sweat glands) releasing noradrenaline or norepinephrine are called noradrenergic or adrenergic neurons. Noradrenaline, dopamine, adrenaline, or epinephrine are collectively called "catecholamines" as they contain a catechol moiety and an amine side chain. The five stages of neurotransmitter release involve their synthesis, storage, release, reuptake and metabolism.

01:22Autonomic Nervous System
The autonomic nervous system (ANS) is a critical component of the peripheral nervous system, primarily responsible for regulating involuntary bodily functions and maintaining homeostasis. It functions in tandem with the central nervous system (CNS) to seamlessly coordinate various physiological processes without the need for conscious control.
The ANS comprises two main divisions: the sympathetic and parasympathetic divisions. These divisions function antagonistically to maintain a dynamic...

01:21Drugs Affecting Neurotransmitter Release or Uptake
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
01:31Sympathetic Signaling
Sympathetic signaling, a vital part of the autonomic nervous system, plays a crucial role in mobilizing the body's resources in response to stress or emergencies. It involves the transmission of nerve impulses from sympathetic preganglionic fibers to postganglionic fibers. This results in the release of specific neurotransmitters and activation of adrenergic receptors.
Sympathetic preganglionic fibers release the neurotransmitter acetylcholine (ACh) onto the ganglionic neurons in the...

01:26Autonomic Nervous System: Overview
The human nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, while the PNS contains nerve cells, clusters of nerve cells, and the sensory receptors that are outside the CNS. The PNS has two types of nerve cells: sensory (afferent) and motor (efferent). Sensory cells send signals to the CNS from receptors, and motor cells carry signals from the CNS to organs, muscles, and...
