THE RETICULAR FORMATION AND ASCENDING RETICULAR SYSTEM: ANATOMICAL CONSIDERATIONS

The Ascending Reticular Activating System from Pontine Reticular Formation to the Thalamus in the Human Brain

INTRODUCTION Action of the ascending reticular activating system (ARAS) on the cerebral cortex is responsible for achievement of consciousness. In this study, we attempted to reconstruct the lower single component of the ARAS from the reticular formation (RF) to the thalamus in the normal human brain using diffusion tensor imaging (DTI). METHODS Twenty six normal healthy subjects were recruit...

A historical note on the ascending reticular formation of the brain-stem.

The concept of the ascending reticular formation has found an important place in psychological and psychiatric theory. Evidence is now convincing that it plays a vital part in the phenomena of consciousness, sleep, and alertness. Its role in the mechanism of conditioning and learning has been widely discussed. It may, therefore, be of interest to the psychiatric reader to be given, in the follo...

REVIEW Reticular formation and spinal cord injury

Study design: Compact literature review to provide basic knowledge of the reticular formation (RF) for clinicians. Setting: United Kingdom. Materials and methods: The anatomical findings were collected from very recently published and well-edited books on neuroscience instead of hundreds of articles that contain materials still requiring test of time and difficult for busy clinicians to digest....

Behavioral functions of the reticular formation.

Studies of the behavioral correlates of activity in reticular formation cells, usually performed in restrained animals, have found units whose discharge relates to sensory stimuli, pain and escape behavior, conditioning and habituation, arousal, complex motivational states, REM sleep, eye movements, respiration and locomotion. Units with these different behavioral correlates were found in the s...
