    Human sleep during chronic morphine intoxication (1975)

    Notes: Abstract The sleep of 6 opiate addicts was studied for 11 nights during 3 phases of a chronic morphine cycle. The control phase consisted of 5 consecutive nights before morphine administration. The induction phase consisted of 1 night at 21–36 days after the onset of morphine administration, when the daily dose was 140–220 mg. The stable dose phase consisted of 5 consecutive nights after the subjects had received 240 mg of morphine daily for 8–19 weeks. No sleep could be studied during the withdrawal phase. Sleep was continuously monitored with EEG, EMG and EOG. Chronic morphine produces signs of a small but persistent sleep disturbance: delta sleep (early night) becomes less stable and shifts toward later in the night, waking state increases during the middle of the night, REM sleep (especially its activated EEG without eye movements) decreases, the REMS cycle increases, and bursts of delta activity (with mean duration of 5–6 sec) increase. Although this disturbance persists throughout the night, it is much less than that seen after single doses of morphine in a previous study. With chronic morphine, therefore, partial tolerance develops to the sleep disturbance produced by morphine. The small but persistent nocturnal arousal during chronic morphine contrasts with the sedation seen during chronic methadone. Both opioids produce an increase in delta bursts during chronic administration, which might be an EEG phenomenon specific to chronic opioid intake.

    LSD and tryptamine effects on sleep/wakefulness and electrocorticogram patterns in intact cats (1978)
    Springer
    Psychopharmacology 58 (1978), S. 223-228

    Notes: Abstract Effects of intravenous infusions of LSD (3.75, 7.5, 15 μg/kg over 5 min; crossover N=4) and tryptamine (0.04, 0.08, 0.12 mg/kg/min for 150 min; cross-over N=6) were compared to saline in intact cats through observation of five sleep/waking patterns. Electrocorticogram (ECoG) was analyzed for frequency band indices and mean amplitude and frequency. LSD increases wakefulness and drowsiness and decreases spindle sleep and rapid eye movement (REM) sleep during the first 75 min (period 1). The increase in active wakefulness and decrease in REM sleep persist during period 2, with an increase in spindle sleep thereafter. LSD increases delta index and ECoG amplitude, with a decrease in ECoG frequency; these effects peaked in period 2. Tryptamine increases wakefulness and drowsiness during period 1, with decreases in spindle sleep and REM sleep. The increase in quiet wakefulness and decrease in REM sleep persist during period 2, but no significant tryptamine effect is seen in sleep/waking patterns after infusion ceases. ECoG frequency increases during tryptamine infusion (periods 1 and 2), while ECoG amplitude increases during periods 2 and 3. Thus LSD and tryptamine both increase wakefulness, decrease spindle sleep, and decrease REM sleep.

    Morphine effects on human REM state, waking state and NREM sleep (1969)

    Notes: Summary After 4 adaptation nights, IM doses of morphine sulfate (7.5, 15, 30 mg/70 kg) and placebo were studied in 8 male postaddicts, using a cross-over design with randomized block analysis to demonstrate significant drug effect. Morphine decreased the number and duration of REM periods, delayed the onset of the first REM period, and possibly increased the time between REM period onsets. Thus, morphine significantly decreased REM state (REMS), but did not alter the pattern of maximum REMS in late night. Morphine significantly increased waking state (WS) but did not alter the pattern of maximum WS in early night. Morphine significantly increased tension, and shifted maximum tension from early night to middle night. Morphine altered EEG sleep patterns; although NREM definitions were thus less certain, morphine appeared to increase NREM light sleep (stages 1 and 2) and decrease NREM deep sleep (stages 3 and 4). After an initial decrease in REMS by 30 mg/70 kg of morphine, an increase in REMS was noted in the third night of the 2 pilot study subjects. The arousal response to morphine seen in post-addicts needs further study in other populations and during the course of chronic morphine use.

    Arc curvature in metric spaces (1980)

    Notes: Abstract Concepts for curvature of arcs in metric geometry (specifically, Menger curvature κ M , Haantjes-Finsler curvature κ H , and transverse curvature κ T introduced earlier by the author) are compared with respect to existence and numerical values. If a metric space satisfies a certain metric inequality shared in particular by Riemannian spaces, then the pointwise existence of κ M on any arc implies that of κ T and the two are equal. In a Minkowskian plane X with strictly convex unit sphere whose boundary U has a C 2 polar representation ρ=ρ(θ), and with $$\bar \kappa _M$$ and $$\bar \kappa _M$$ the Menger and transverse curvatures relative to the underlying Euclidean metric, the following formulas are proved: At any point p on an arc at which $$\bar \kappa _M$$ and $$\bar \kappa _M$$ exist, $$\kappa _M = \bar \kappa _M \sqrt {\rho ^{2 + } 2\rho ^{'2 - } \rho \rho }$$ and $$\kappa _T = \bar \kappa _T \frac{{\sigma _1^{3/2} (T_p )}}{{\sigma _2 (T_p ,T_p^ \bot )}},$$ where T pis the tangent at p, T ⊥ pthat line to which T pis metrically perpendicular, and σ1 and σ2 are certain real-valued functions defined on lines of X. The result of this is that if κ* is the classical curvature of U p≡U+p at U p∩ T p, $$\frac{{\kappa _M^2 }}{{\kappa _T^2 }} = \frac{{\kappa ^ * \sigma _1^{3/2} (T_p^ \bot )}}{{\sigma _2 \left( {T_p ,T_p^ \bot } \right)}},$$ from which it follows that the values of κ M and κ T are not equal for metric spaces in general even when both exist.

    A nonalgebraic approach to the theory of linear topological spaces (1977)

    Notes: Abstract The basic theory developed in the setting of an algebraic system endowed with a topology which renders the operations continuous (e.g. a topological linear space) can be produced entirely by geometric (set-theoretic) notions without using algebra. This theory affords an interesting synthesis of classical results, and is more general. For example, our theory applies to a larger class of spaces than linear topological spaces, but is powerful enough to prove the appropriate formulation in this setting of the Krein-Milman theorem on extreme points. This theorem is the goal of this particular article, as an example of the direction which the theory can be made to take.
