    Unitary responses to tone stimuli obtained from the medial geniculate body were investigated in cats and the following results were obtained.
    1)The unitsres ponding to tone stimuli were classified into 3 types.The first type showed a single spike or burst of spikes in response to the onset of tone stimulus.Thesecond type showed the response which consisted of asingle spike or a burst of spikes and a following silent period and then continuous firing.In the third type, theres- ponse was continuous firing with relatively long latency.The units of these types accounted for 86%, 6%and7%, respectively.
    2)Most units of the first type responded with a short latency of less than 20msec.In some of the rest, the latency of the response was more than 100msec.In the others, the latency was more than 100msec at high intensity, but less than 20msec at low infensity.
    3)In about 39% of the response areas obtained, eachshowed a single dip in its low intensity limit and in36%, two or more dips were observed.The remainder included many varieties.

    A blindfolded chicken is placed on a perch without any restriction and is see-sawed 200 times in 800 seconds daily for four weeks.At first the chicken is unable to adapt itself to this motion, i.e.the head, trunk, wings and tail move violently with each cycle of see-saw and finally it falls off the perch to the floor.However, with the daily repetition of this see-saw motion the chicken becomes capable of adapting itself smoothly to the unstable postures of the head, trunk, wings and tail are countermanded by new stable postures which are just the mirror image of the postures at the beginning.Fukuda et al could demonstrate that these new postures resulted from establishment of a labyrinthine reflex of a higher order, which enables the chicken to adapt to the dynamic motion, therefore Fukuda named this process"Training" and this result"Training effect
    In Fukuda's investigation, a blindfolded chicken was placed on a perch without restriction in any way.Therefore, not only the vestibular labyrinths but also the proprioceptive organs should have been stimulated by the see-saw motion.In order to know how the proprioceptive organs participate in the establishment of the training effect (a labyrinthine reflex of higher order), the head, neck, trunk, wings and tail were restrained separetly or combinedly in the following various ways and the chicken was see-sawed 200 times in 800 seconds daily for four weeks.The groups of chickens which were subjected to various types of restraint during the training are arranged below in the order of the facility with which the training was completed.
    1.Blindfolded chickens which were placed on a perch without restriction in any way.
    2.Blindfolded chickens of which the trunk and wings fixed with a plaster cast and which were placed on a perch made in a box.
    3.Blindfolded chickens of which the trunk and wings were fixed with a plaster cast and which were placed in a box without any perch.
    4.Blindfolded chickens of which the head, trunk and wings were fixed with a plaster cast and which were placed in a box without any perch.
    The results show that the training effect is gained by virtue of combined functioning of the vestibular labyrinths and the proprioceptive organs distributing in the whole body.Therefore the author believes that the training for the air and space flight should be performed in this way;i.e. not only the vestibular labyrinths but the proprioceptive organs of the whole body should be simultaneously trained.
    Even a trained chicken cannot maintain a good equilibrating posture during see-sawing and falls to the floor, after lapse of a month's untrained interval.However it soon recovers to its good equilibrating function through repetition of the see-saw motion for a few days.This result proves correctness of the proverb clearly and scientifically. "He harks back to his use"

    The present work was designed to study the influence of the stresses upon the inner ear.Guinea pigs were put in the state of stress by using electric stimulation(80V, 0.7sec., at 10sec.intervals) and light stimulation(electronic flash or electric bulb), and the influence of these stimulations upon the inner ear was observed.
    A) The susceptibility to acoustic trauma in animals was excited by electric or light stimulation:
    In the control animals, acoustic stimulation with 2000cps of 120phon for every one hour of ten successive days caused only slight degeneraation of the hair-cells, while in the animals excited with electric stimulation at the same time, the severe destruction of the structures of the organ of Corti was observed.
    Light stimulation did not change the susceptibility to acoustic trauma.
    B) In the animals excited with electric and light stimulation for 24hours, the result obtained as follows:
    No pathological change of the inner ear was observed.Preyer's reflex test showed an impairment, but C.M.potentials were mostly unchanged. Sodium decreased in perilymph and increased in endlymph.

    With regard to the estimates, for hearing threshold.variation of the threshold of the normal ear during long term, and the effect of training on threshold, automatic audiometry fixed in frequencies at 4000cps for 4 min., using continuous tone and interrupted tone(10 ips, partially 4 ips) was repeatedly performed 5 times in1or 2 weeks. The subjects employed consist of the following 2 groups;in the first group the subjects were well trained with this testing method, in another group the subjects had no its experience.
    The conclusions obtained from the present study are as follows:
    1.Hearing threshold
    1) The variations of threshold in all but 3 of the untrained subjects were essentially similiar to those in the trained subjects and distributed within ±5db, but at times they were above 10db.
    2) Three individuals of the untrained subjects indicated a marked threshold-rise or significant fluctuation in continuous tracings, particularly in the first and second test.It could be suggested that the irregularities of such results may be due to fluctuations in attention and changes in the subjects criteria of hearing or some mechanical factors.
    3) TTS for 4min in the trained subjects seemed to be a lower amount and smaller variation than that in the untrained subjects.While the values of TTS by continuous tracings were larger than those by interrupted tracinge in the untrained subjects in the trained subjects there are little difl erences between continuous and interrupted(10 ips) tone, and interrupted tracings(flips) indicated u lower value of TTS.
    2.Excursions of Bekesy tracings
    1) The mean magnitude of excursion amplitude of Bekesy tracings, by using continuous tone and interrupted tone, in the untrained subjects were found to be more reduced and smaller on than that in the trained subjects.
    2) The significantly reduced width in the process of the continuous tracings was shown in some of the trained subjects.

    The author presented the personal experiences with four cases of vestibulotomy in chronic otitis media and reviewed the cases appeared in the literature.
    It is the most important to protect the labyrinth against occ urrence of post-operative labyrinthitis after opening the oval window.Better results may be obtained both by immediate obliteration of the opened window and by massive use of antibiotic.In the cases of antibiotic sensitive infection, the function of the labyrinth was not impaired after vestibulotomy.They showed the marked improvement in hearing.
    On the other hand, the post-operative labyrin thitis occurred, resulting in deaf, in other two cases with antibiotic resistant infection.So the author is of opinion that an ear with antibiotic resistant infection is acontraindication for vestibulotomy.
    In all our cases, the stapes was removed accidentally, and the oval window was immediately obliterated with a connective tissue plug.After completing a radical operation, the plug was removed and the opened window was permanentally covered with a temporal fascia graft.The second operation was all carried out as type IV.Reviewing the literature, most authors, except for Weichselbaumer(1965), seem to perform an one-stage operation, in which a type lll was often obtained by creating a columella.The author discussed the value of such one-stage operation.

    Rhinophyma is not very common in Japan. Authors experienced .case of typical rhinophyma of 82 years old male and performed plastic operation by using free skin graft taken from his right thigh after external nasal growth was removed. Through our case and references, the below mentioned were emphasized;
    1) not to traumatize external nasal perichondrium or cartilage
    2) to oppress transplanted skin graft adequately in order to avoid exsudate-retention under transplanted skin graft
    3) to select the region where skin graft taken to satisfy the adjustment of color of postoperative external nose

    Thirteen cases of Nasopharyngeal malignant tumor, especially about their early diagnostics by the radiographical and neurological examinations are reported (Tab.1).These thirteen cases are nine in the male and four cases in the female.
    Aural troubles (deafness, tinnitus, sensations of fullness, autophony, etc.) are the initial symptoms in five cases, nasal troubles (nasal obstraction, epistaxis, etc.) four cases, cranial nerve involvements two cases, the lump of side neck and sore-throat one case (Fig.3).It took 7.8 months on average in our cases to make sure the primary lesions since some initial symptoms appeared.
    The cranial nerves are involvd in our eight cases, and those details are seven cases in V and VI (Fig.11), five cases in IX (Fig.12), four cases in (Fig.7.8.9.10) and XII (Fig.15), three cases in IV.VII(Fig.17.18) X.XI(Fig.13.14), two cases in II and one case in I and VIII cranial nerve.We observed only one case of Horner's syndrome(Fig.16).
    Through our experiences, the radiographical examinasions, neurological examinations and transpalatal biopsy are emphasized as the diagnostic aids for the intracranial spread of the submucous infiltrative type of nasopharyngeal tumor.The most valuable projection is the axial view by which not only bony erosions of the base of the skull but also the findings of choana are able to be estimated(Fig.21, 22, 23).The frontal and lateral view of the skull also presents soft tissue tumor in the posterior wall of the nasopharynx and bony erosions of atlas, axis and condylus occipitalis, etc(Fig.24, 25, 26).Laminagraphy (Fig.27, 28, 29, 30, 31), contrast nasopharyngography(Fig.32, 33) and cerebral angiography are also valuable in some cases(Fig.34).The modified occipito-mental view is the most fit for observing foramen rotundum and fissura orbitalis superior(Fig.35) and Rhese's projection for canalis opticus(Fig.36, 37).
    Although it is not so difficult to find out the proliferative-type tumor in the nasopharynx because of its nasal and aural troubles.But on the contrary in the submucous infiltrative-type nasopharyngeal tumor is very hard to be diagnosed before complicated with some cranial nerve le. sions, metastatic cervical lymphnodes, etc.
    As above mentioned, the diagnosis of the sub. mucous infiltrative-type of nasopharyngeal tumor is usually very difficult and besides its prognosis is very poor as compared with prolifelative type tumor, so we used to carry out transpalatal biopsy without any hesitations whenever such sub. mucous infiltrative-type of nasopharyngeal tumor is suspected

    The eye-speed during the quick phase of nystagmus appears to be of diagnostic importance for neurotological examination.
    The author measured the eye-speed of optokinetic and vestibular nystagmus as well as the eye-speed during voluntary saccadic eye movements.
    The experimental results obtained are as follows:
    1) The eye-speed during voluntary saccadic eye movements was faster when the excursion of the eyes was larger.The maximum of mean values of saccadic eye movements was as fast as 502°/sec with the standard deviation of 61°/sec.
    2) The slow phase eye-speed showed much smaller variation in either of optokinetic and vestibular nystagmus.
    The maximum slow phase eye-speed was around 100°/sec for post rotatory nystagmus when the stimulus was applied by suddenly stopping the rotatory chair at 180°/sec and was around 40°/sec for caloric nystagmus when the stimulus was applied with 20cc of ice water irrigated for 10sec.
    3) The quick phase eye-speed of optokinetic'nystagmus induced by optokinetic stimulus of 58, 4°/ sec was 321°/sec with the standard deviation of 61°/sec.
    The quick phase eye-speed of vestibular nystagmus induced by rotatory and caloric stimulation was 152°/sec with the standard deviation of 290°/ sec.The quick phase eye-speed remained constant, though with a considerable variation, that was different from the slow phase eye-speed which changes in the course of stimulation.The quick phase eye-speed, however, appeared to have some dependence on the magnitude of eye excursion during the quick phase of nystagmus.
