SummaryConsciousness, the awareness of self and environment, requires both arousal and mental content; the anatomic substrate includes both reticular activating system and cerebral cortex. Coma is a state of unconsciousness that differs from syncope in being sustained and from sleep in being less easily reversed. Cerebral oxygen uptake (cerebral metabolic rate of oxygen [CMRO2]) is normal in sleep or actually increases during the rapid eye movement stage, but CMRO2 is abnormally reduced in coma.
Table of Contents- Consciousness, the awareness of self and environment, requires both arousal and mental content; the anatomic substrate includes both reticular activating system and cerebral cortex
- Coma is clinically defined by the neurologic examination, especially responses to external stimuli
- Fever may imply infection or heat stroke; hypothermia may occur with cold exposure (especially in alcoholics),
- In their classic monograph, Plum and Posner (1980) divided the causes of coma into supra- and infratentorial structural lesions and diffuse or metabolic diseases
- Flexor postures generally imply a more rostral lesion and have a better prognosis than extensor posturing, but the pattern of response may vary with different stimuli, or there may be flexion of one arm and extension of the other
- Pupillary abnormalities in coma may reflect an imbalance between input from the parasympathetic and sympathetic nervous systems or lesions of both
- With few exceptions, metabolic disease does not cause unequal or unreactive pupils
- The EEG may also reveal asymmetries or evidence of clinically unsuspected seizure activity
- During the downward course of transtentorial herniation, there may be hemiparesis ipsilateral to the cerebral lesion, attributed to compression of the contralateral midbrain peduncle against the tentorial edge (Kernohan notch).
- The clinical picture of pontine hemorrhage (i.e., sudden coma, pinpoint but reactive pupils, and no eye movement) is characteristic, but if the sequence of signs in a comatose patient is unknown
- VEGETATIVE STATE
- BRAIN DEATH

Summary“For almost thirty years I repeatedly saw one and the same dream: I would arrive in Vienna at long last. I would feel really happy, for I was returning to the most serene time of my life.” In this quote, Alfred Schnittke, in the final years before his death, recaps his pleasant times in Vienna, Austria. Schnittke, however, was not born in Vienna, but in Engels, on the Volga River, in the Soviet Union, on November 24, 1934. Schnittke’s father was born in Frankfurt, Germany into a Jewish family of Russian descent, who later moved to Russia. His mother was a Volga-German, born in Russia. In 1946, Schnittke began his musical training in Vienna, before moving to Moscow, Russia in 1948. In Moscow, Schnittke was able to complete his music education at the Moscow Conservatory, where he also taught from 1962-1972. Following his teaching career, Schnittke began to compose film scores as a means for supporting himself. During this time, he studied with Evgeny Golubev, a Russian Soviet composer. Thereafter, he began composing music other than film scores, but became a target of Soviet bureaucracy. Later in his life, Schnittke suffered a series of strokes, and way actually pronounced dead on several occasions. After his stroke in 1985, Schnittke remained in a coma for quite some time, but partially recovered, and continued to compose music. A final stroke left him almost completely paralyzed, and he died shortly after that in 1998.
Table of Contents- 'For almost thirty years I repeatedly saw one and the same dream: I would arrive in Vienna at long last
- Schnittke's music was known for having an extreme Russian sound
- Prior to 1968, many of Schnittke's compositions contained elements of serialism (like that of Arnold Schoenberg)
- In one of Schnittke's compositions specifically, A La Albeniz, many of these musical characteristics are demonstrated
- A similar problem arises when discussing public reaction to Schnittke's music
- Schnittke's music is melodic and emotional, and not in the least bit grotesque

SummaryRife with evil, the town needed to be destroyed. Piety had built Phrygia, but gluttony, unfaithfulness, and greed had razed the now repugnant country. Disgusted by the drinking orgies, sexual perversions, and absence of worship, Jupiter and Mercury watched from the Heavens. Phrygia’s time had come. Jupiter set out to destroy the city and all its people immediately, but Mercury, his son, held him back.
Table of Contents- Shocked by his boy's sympathy, Jupiter paused for a moment and considered his son's advice.
- Jupiter prepared to turn the town to ashes.
- Baucis and Philemon caught a glimpse of Jupiter and Mercury climbing the hill.
- Baucis set the table hurriedly and placed some fruit and olives on the table to keep the guests occupied.
- Realizing not the exact identity but rather the importance of their guests, Baucis and Philemon spared nothing in their house.
