Motor Exam: Anatomy: Spinal Cord Lesions
Spinal cord lesions often give UMN signs below the level of the lesion (from effect on the corticospinal tract) and LMN signs at the level of the lesion (from effect on the ventral horn or ventral nerve root). LMN signs are good for locating the level of a spinal cord lesion. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examinatio

NeuroLogic Exam: Introduction: Somatosensory Tracts
Now let's add the 2 ascending sensory systems that give us important clinical information for localizing lesions in the neuroaxis. The first system is the spinothalamic tract (pain and temperature) diagramed in light blue and the second is the Dorsal Column- Medial Lemniscus system (discriminatory touch and position sense) outlined in dark blue. Two important anatomical (and hence clinical) points about these two systems: - The spinothalamic tracts cross almost immediately upon entering the cord

O Panama
'O Panama,' 1985, a video drama, was created by James Benning, based on a story by Burt Barr. A series of short images or vignettes, some of which are repeated, build to tell the story of a feverish man (Willem Dafoe) in a city apartment remembering time he spent in Panama, probably as a soldier. The suggestion is that as he endures the fever, he is visited by recollections, visualizations, and hallucinations of other places and events.

3.4 Biological approaches

Certain kinds of psychological disturbances may be seen as ‘malfunctions’ of the brain. If a psychological problem has an obvious biological explanation, then it may be possible to direct therapeutic approaches at this level. However, as we have seen, it is difficult to identify precise biological causes for complex psychological phenomena. Even if this were possible, it would not always be practicable to use treatments to change the underlying biological factors. Genetic ‘exp
