Delayed responses to visual stimuli are performed by dogs with different delay maximums. In quiet, immobile dogs the maximum delay of alimentary response to a visual stimulus may be 10-15 min. In active, easily excited dogs the delay maximum does not exceed 3 min. The duration of delayed reaction greatly depends- on the repetition of the experiment, i.e. on training. Maximum delay is achieved by alternating short, delays with longer ones until the maximum is reached. The maximum delay is reached much faster and far nore successf~Alyin quiet, immobile dogs than in easily excited dogs. However, the Rbil- LSard 1/2 ~'7ACC NR AT ity of the animals to produce delayed responses does not exclusively depend on train-1 ing. Animals may produce delayed responses at the first trial, some minutes after they have seen the food or heard the signal. The delay of responses to conditioned stimuli (bell, tone) was somewhat shorter (8-12 min). The miximum delay of re- - sponses to conditioned natural signals (noise of food basin) was significantly shorter ~3-5 min). In experiments with visual stimuli and conditioned food signals, unusual stimulation during the delay period, even feeding or removal of the animal from.the -cage, did not disrupt the delayed response. Maximum delay of response to conditioned sound stimuli is somewhat more difficult to achieve than with visual stimuli. The animals were also able to produce delayed responses to vestibular stimulation. The maximum delay for these stimuli is 3-4 min. These findings are theoretically analyzed in the light of psycboneural regulation of the behaviour of higher ver- tebrates. It is concluded that delayed reactions are governed mainly by th6 laws of the psychoneural activity producing images of the external world, and not by the laws of conditioned activity.

Sovremennyye.problemy deyatel'nosti i stroyeniya tsentral'noy nervnoy sistemy (Present problems of the activity and structure of the central nervous system), 3-21 i TOPIC TAGS: central inhibition, nervous system inhibition, CNS, general inhibition, reflex inhibition ABSTRACT: Sechenov's concept of central inhibition is essential to the physiological analysis of psychic activity. Sechenov found that stimulation of the thalamus, mid- brain, and medulla oblongata in frogs depresses spinal cord reflex activity, affec ing both the entire skeletal musculature of the extremities and the automatic activity of the blood and lymphatic systems. He believed this general inhibit ton to, occur througit the- eytIAtation of- depressor neuroni, scattered through the midbrain and upper medulla oblongata, which affected the spinal cord in the same way that the varus nervd- affects the --- Initial re di is in- X movements after s mulation of the SellSOTY nerves of the extremities. Th hibition, like thAt following thalamus, midbrain, and medullary stimulation, i4 baged Card 1/3 FACC on decreased excitability of cutaneous muscular reflex centers along the whole spinal cord axis. Sechenov discovered that inhibition and excitation might occur simultane ously: soon after the cessation of inhibiting sensory nerve stimulation, the state of depression is most often briefly replaced by increased reflex apparatus excitation. Later studies by many scientists have shown that general inhibition is evoked not only, by direct stimulation of various parts of the brain, but also by adequate stimulationi of receptors, even with threshold stimuli which produce no external motor -General inhibition is-an- Integral part- of -nny Yeflex or-behavloral reasponse, and assures the ihtegrity.of the central nervous system.~ Any excitation of the definite nervous complexes which adapt the organism to change in the environvient is accorr panied by decreased excitability in the rest of the nervous system. Excitation pro- cesses are thus focusrd in c ertain -neuron-chains by bl ocking the -simultaneous- stimula tion of othei- chains- 6y.. different external stimuli. This general inhibition can in- volve excited neuron chains as well. If the inhibition is strong enough, it can de- press excited chains. In this case, excitation and inhibition occur antagonistically in the same elements. Their algebraic summation determines whether excitaltion or inhibition will prevail for that element as a whole.. Brain stem and spinal cord structures were found to participate in general inhibition in both intact and decere- brated animals. Certain parts of the reticular formation, when excited, have a de- pressant effect on both the brain-and the spinal cord. In the spinal cord it is the gelatinous substance which acts as the IrMbitory mechanism. Recent data indicate that inhibition by the gelatinoup,,.substance is based, on the aeneration- of slow poten- tials in the dendrites of gela~inqus neurons nndLproprial and p~ricorneal'intermediate Card 2/3 __66 ACC NR: AT5024224 neurons under the effect of collaterals of ascending and descending tracts. Currentsi corresponding to these potentials act anelectrotonically on axasomatic synapses to block incoming peripheral impulses, and the electrical field around activated den- drites anelectrotonically blocks nerve fibers passing through it. The increase in reflex excitability following inhibition after cessation of stimulation occurs in the same elements that were inhibited, as Sechenov suggested. This increase in total re- flex excitability seems to result from cessation of the anelectrotonic effect and to be analogous to nerve stem polarization near the anode after the polarizing current is switched off.

After 12 hours the precipitate is filtered off (paper-filter "Blue Band") and washed with 20 ml 2 N HC1.

Glycerine is oxidized in a medium of an eighty-percent acetic acid in the presence of potassium acetate by means of an excess of a voliLmetric solution of ead tetraacetate. -"he excess of the reats-ent is then determ=ed by a potentiometric titration with a volumet-ric solution of hydroquinone. nhe method is simple and yields more accurate results than the bichromate method.

Carbon dioxide and water are obtained from methyl, acetic acid from ethyl, prorionio acid from propyl and acetone from isopropyl alcohol. Oxidation of butyl and isobutyl alcohol produces many products and cannot be described by a simple equation. Conditions under which the oxidation can be used for analytical titration work are described. 5 Figures, 2 Tables,, 13 Western, 6 Czechs 2 Indian references.

Ing case by carbon monoxide during exca- poison vation of a well PRACOVNI LL'KARSTVf (Praha) 1954, 6/5 (301) A case is described of sudden death by carbon monoxide poisoning In the making of a well, where an unknown explosive was employed. A man went down 15 min. after the explosion without sufficient protection. Half an hour later he was pulled out dead. An analybis of the air made immediately showed that his death was caused by carbon monoxide, the concentration being 6.3 mg, per litre air. The blood of the dead man contained 50% CGHb.

B e r k a I Brno Czechoslovakia. ACTA MED. SCAND. 1957, 157/2 (fff-TRTTajcG 3 illue. 3 The method depends on the fact that metallic paliadium will separate from a solu- tion of its chloride at a rate and in an amount which is proportional to the concen- tration of CO present in a.sample of blood. The reaction is carried out in a micro- diffusion apparatus and the amount of Pd, released can be eFtimated by 3 different methods. With all 3 methods it is possible to estimate COHb in blood samples in the range from 5 to 40-50%. The most rapid (5 min.) and simplest method do- pends upon the colour change of an indicating gel containing Pd aWcomolybdate. Noggle - Gainesville. Fla. "ERKA, I.
