Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Adrenergic Neurons: Neurotransmission

Adrenergic 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.
Synthesis: Catecholamine synthesis requires tyrosine, which is taken...

Drugs Affecting Neurotransmitter Release or Uptake

Drugs 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...

Drugs Affecting Neurotransmitter Synthesis

Drugs Affecting Neurotransmitter Synthesis

Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

Depressive Disorders: Etiology

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Summary

Postmortem brain tissue studies suggest a norepinephrine deficiency in depression and suicide. However, more rigorous research is needed to confirm noradrenergic neuropathology in psychiatric disorders.

Area of Science:

Neuroscience
Psychiatry
Neurobiology

Background:

The noradrenergic system plays a crucial role in mood regulation.
Alterations in this system are implicated in psychiatric disorders like depression and suicide.
Postmortem brain tissue analysis is a key method for investigating neuropathology.

Purpose of the Study:

To review existing research on the noradrenergic system's neuropathology in psychiatric disorders using postmortem brain tissue.
To evaluate the evidence for and limitations of postmortem studies in this field.

Main Methods:

Systematic review of studies employing postmortem brain tissue analysis.
Focus on research investigating the noradrenergic system, particularly in depression and suicide.
Analysis of findings related to norepinephrine levels and function.

Main Results:

Postmortem studies provide data consistent with a norepinephrine deficiency hypothesis in depression and suicide.
Current evidence from postmortem studies is not irrefutable regarding noradrenergic neuropathology.
Technical limitations and reproducibility issues affect the interpretation of findings.

Conclusions:

Postmortem research offers valuable insights but has inherent limitations.
Further rigorously conducted postmortem studies are essential.
Pinpointing specific noradrenergic neuropathologies in psychiatric diseases requires enhanced research methodologies.
