ジャーナル フリーThe cortical projections of the Saccule were lations on the Macula sacculi, and observation was eating linear acceleration.
All the experiments were performed on cats, and the cortical responses were induced by the methode of microelectrodes as the form of unitary spike discharge.
The results were as follows :
1) Responses to the mechanical stimulation on
the Macula sacculi.
Cortical evoked potentials were recorded from the anterior ectosylvian gyrus and the anterior descending limb of the suprasylvian gyrus of the contralateral side.
2) Responses to the electrical stimulation.
Cortical evoked potentials and unitary spike discharges were observed on bilateral sides o anterior ectosylvian gyrus and on the anterior cending limb of the suprasylvian gyrus.
The latency of the contralateral responses
3) Responses to the linear acceleration.
Due to the stimulation(the repeated li acceleration at the directions of the axis of occipital and of the frontal axis) the frequen the spike discharge of the cortex was remarl increased.
General conclusions drawn from these suggest the presence of the cortical projectic Saccule and that impulses from peripheral organs evoked by linear acceleration are prol transmitted to the cerebral cortex.抄録全体を表示PDF形式でダウンロード (2207K) -

ジャーナル フリーThe frequency analysis of the changes of EEG to the auditory stimulus was carried out, to study if the method can be applied clinically to the objective audiometory.In recording the changes in the instant value of EEG to the sound, a limit sound level to which the changes were recognized (threshold), and the relation to the background activity (especially the stages of natural sleep) were observed.
The bipolar electrode was implanted chronically in the Vertex of rabbits.The stimuli were the pure tones with the duration of 5 seconds and a minimum of 30 seconds was allowed to elapse between the stimuli.
The frequency range with some changes in the instant value to the tones at the lower intensity was mostly 9c/s, especially 7c/s less, and the percentage of the positive changes was as below, highest in the drowsy stage and lowest in the deep sleep.
But the considerable percentage of occurrence of the false-positives required the presentation of the number of same tone, making accuracy not posible.
The results lead the author to conclude that this method is not suitable for human objective audiometory.抄録全体を表示PDF形式でダウンロード (543K) -

ジャーナル フリーThe purpose of this experiment was to study the changes of the responsiveness of the respiration to the repetitive sound stimulation.
In rabbits, respiration was studied using the gum tubes full with the saturated solution of ZnSO4 and in the sounds, by the bell stimuli at 65.68 phon and 115., .118 phon with the duration of 5 seconds and the intervals of 10 seconds.
To the repetitive stimulation, the following results were obtained.
(1) Generally, the respirations increased and ned. caused the disappearance of the responsiveness of the respiration and which progress was wavelike and at first recognized in the quicker background respiration.
(3) At 115.118 phon, the habituation was not yet recognized with repetitive stimulation of a thousand and more than several hundreds.
(4) The habituation was recognized faster in the excitement by pricking the face regions with a needle.抄録全体を表示PDF形式でダウンロード (552K) -

ジャーナル フリーIn recent years, it has become apparent that the directional hearing capacity in binaural hearing correlates with the perceptive hearing disorders.
From such a medical significance, the experiment was carried out in order to research the possibility of clinical application of the differential diagnosis of hearing impairment causing central auditory pathway.
The experiment was performed with the use of the interaural time difference generator fitted with a sound generator, two movable microphones, two attenuators and earphones.
Normal hearing subjects, equipped with earphones, listened acoustic stimuli composing of variable interaural time and intensity differences and discriminate the difference of the position of the two sound impressions which exist in the listener's head or in its close proximity. The interaural time difference can be expressed in the distance between the two microphones in this apparatus.
The better discrimination orders of localization of a sound impression are noise, voice bubble and pure tone.
In view of the band noise, sound impression consisting 600_??_850cps can be localized most easily.
In respect of discrimination of angular localization for a pure tone, the interaural time difference is not so effective than for the other kinds of sound i.e. voice bubble and noise.
The function of the angular direction is the best at median plane.
The value of the discrimination of sound impressions is generally smaller in lateral side of median plane and it is difficult to discriminate two sound impressions deviated over the angle of 45_??_60°by intensity or time difference alone.
The difference of hearing loss between two ears to enable angular direction of two sound im.uression is annroximatply lass than 3dB.抄録全体を表示PDF形式でダウンロード (941K) -

ジャーナル フリーThe authors observed speech sound of the five ation and sound spectrograph of the consonants.
1) By hearing test, there are 5 cases who show over. ring among the deaf childrens and these childrens of hard of hearing can not get better percentage than 50% by lip reading alone. ciation show 73.7% at the highest, 18.0% at the lowest and 39.8% at the average.
There are only 3 cases who show the higher percentage than 50%.
It was revealed that the childrens of not great impairment of hearing can not pronounce correctly such sound as D, G, Z, KY, and moreover that the deaf childrens cannot pronounce such sound as K, processes of the little residual hearing and help the speech articulations.
4) By Sonagraph test, it was revealed that the disturbance of the consonant was caused by the disturbance of the consonant wave, uncertainly of ing vowel.
The disturbance of the following vowel was caused by the deficiency of dynamic self control activity of the hearing.抄録全体を表示PDF形式でダウンロード (1619K) -

ジャーナル フリーBrain hernia is an unusual complication of mastoid surgery.Few cases are reported, at least, in Japan.
The authors experienced a case of brain hernia, toid and lateral sinus. to the hospital, August 29, 1963, with a complaint of tumor at the retroauricular surgical scar on the left side.
Three years prior to the admission she had a mastoid surgery, because of the meningeal signs media.As the simple mastoidectomy was not enough to cease the symptoms, the second operation was performed three months later on the lateral sinus lesion, after which her disturbances diminis hed.
But a few months before the admission, patient happened to notice a soft, round tumor the old mastoid wound.
An exploratory puncture revealed a cerebr, nal fluid cyst, although she showed no other rophysical signs.
The tumor extirpation was carried out, histological examination confirmed a cerebellar rnia which escaped out beyond the dural de around the region of cisterna ambiens.
After the surgery no serious mental and p ical symptoms were observed except the leakag cerebrospinal fluid out of the wound, which treated successfully with the transplantation pedicle skin flap.
The patient made a satisfactory recovery, was discharged on November 11, 1963.抄録全体を表示PDF形式でダウンロード (2172K) -

ジャーナル フリーDie Verfasser haben schon ihre Erfahrungen veröffentlicht, daβ durch Verabreichung fettreicher Kost vor der Operation der Duktus bei der radikalen Neck-Dissektion auf der linken Seite deutlich wahrnehmbar werde and dadurch die Verletzung desselben vermieden werden könne.
Durch these Methode haben die Verfasser einen sehr interessanten Verlauf des Duktus im Operationsfeld bei 2 Patienten feststellen können.Beim ersten Fall(ein 62jähriger Beamter mit Kehlkopfkarzinom) war der Duktus in die V.jugularis externa eingemündet.Beim zweiten Fall(ein 56jahriger Beamter mit Kehlkopfkarzinom), haben di Verfasser einen deutlich verastelten mit Chylus gefüllten Gang in der rechten Supraklavikulargrub feststellen können.Später haben die Verfasser aucldas deutliche Vorhandensein des eigentlichen Duktus bei der linksseitigen radikalen Neck-Dissektioi wahrgenommen.Da die Verfasser den Duktus auder linken Halsseite vorher weder verletzt noel unterbunden haben, muβ dieser mit Chylus gefiillt Gang auf der rechten Halsseite eine Variation sein die dem I., IV.oder VII.Typus nach A d a c h entspricht.(Autoreferat)抄録全体を表示PDF形式でダウンロード (1509K) -

ジャーナル フリーThe problems of children with retarded speech have been noticed by many clinicians such as iatrists and psychologists. tions on 466 delayed language cases who visited the hearing and speech clinic for children in E.N.T. Department of Tokyo University Hospital since 1960 to 1962.
Subjects are classified into following groups nce) der 84 of IQ)
3) mutism due to hearing disturbance
deaf mutism(threshold is over 61 dB)
Investigations are made on method of diagnosis, evaluation of speech ability, etiology and treatment.
The informations obtained from parents are ation is necessary for correct evaluation of speech and hearing ability.
Sixty per cent of the cases are boys and fourty per cent are girls, and most of them(70 per cent) are under 4 years of age.
The further classification and investigation can be performed in accordance with correct evaluation of speech ability.
Poor nurseing environment and brain damages followed by abnormal progress of pregnancy and delivery, especially asphyxia, are considered to be significant as the causes of audimutitas.
On the mentally retarded cases, hereditary pre. dispositions such as mental retardation, neurosis and intermarriage are prominently noted.
Clinically, a group of slight deafness is not adequate because 8 per cent of them revealed profile of the audimutitas and another 26 per cent have mental deficiency.Causes of slight deafness is not clear.
Hereditary predispositions(impaired hearing, intermarriage and neurosis), disturbance of pregna ncy, abnormal delivery, childrens disease with higi fever are considerable factors as the cause of dea mutism and medium deafness. Patients were treated medically by γ-aminobu tilic acid and others, and given education by speed therapy.Group therapy for audimutitas childrei is markedly effective and attention to early con mencement of therapy should be paid.抄録全体を表示PDF形式でダウンロード (1758K)
