    The change in response properties of the cortical cells caused by delivering continuous tone in addition to the tone burst was studied. The effect was more conspicuous in facilitation rather than inhibition, and observed mainly in the neurons of the narrow response area.
    Facilitation occurred even when the two stimulating sounds did not gave a beat, and the effective frequency range of the continuous tone of some neurons showed three frequency bands far apart from their characteristic frequencies. The effects also depended on the intensity relation of the two tones. In some cortical cells, on response underwent different changes from that of the off response. The threshold values were lowered especially at the high threshold frequency range of response area, and a new peak appeared in the response area.
    These facilitatory effect caused by the two-tone stimulation suggests that the cortical cells were sensitive to the change in frequency and intensity of the tonal stimuli, which seemed to be related to the discrimination of the complex sound.

    Unitary responses to tone stimuli obtained from the cerebellar cortex were investigated in cat. Inhibition or phenomena similar to inhibitions among the responses were discussed as followed:
    1) Eighty-two out of 160 units showed some reactions to tone stimuli. While in 7 out of 160 units activities were suppressed by tone.
    2) In 4 out of the 7 units suppression occurred with a latency of 10 to 15 msec and lasted during the tone burst. One of the 4 units showed an “on-response” to a tone burst of high intensity before the activity was suppressed. With low intensity tone the activity of unit was suppressed without excitation.
    3) In the other 3 out of the 7 units suppression occurred with a latency of several msec and terminated with a duration of 10 to 20msec and was followed by an indistinct response of continuous type.
    4) In a unit which showed an“on-response”a short silent period followed the response at all but two frequencies tested. At those two exceptional frequencies this silent period was not seen.

    In 1945 Cogan reported a syndrome consisting of nonsyphilitic keratitis with vestibulo-auditory dysfunction. Since Cogan's original papers were published, more than thirty additional cases have been reported. In Japan, however, no case has yet been reported.
    We report in this paper a case of a 62-year-old house wife with left interstitial nonsyphilitic keratitis and vestibulo-auditory symptoms.
    Patient had had recurrent keratitis of left eye for eighteen years and began to have frequent attacks of rotatory vertigo, tinnitus, nausea and headache for the past four years. Hearing loss was also noticed. On September 1963, she had blurred vision and was diagnosed as left interstitial keratitis.
    At the same time she had frequent episodes of vertigo with nausea, headache, tinnitus and hearing loss.
    Laboratory tests including hematology, blood chemistry and urinalysis were all normal. Blood serology was negative. ECG indicated left ventricular hypertrophy. She was treated with steroid-antibiotic eye solution and was placed on oral steroid drug. Audiometry showed bilateral sensorineural hearing loss. (Fig. 1) Tracings by Békésy-type audiometer suggested cochlear lesion. (Fig. 2) TTS was negative. Caloric tests revealed directional preponderance to the right. There was a nystagmus by positsonal change. (Fig. 3 and 4) As ophthalmic findings have gradually shown the herpetic lesions, ophthalmic solution (I.D. U.-5-Iodo-2-deoxyuridine and Chloromycetine has been used with some benefit.
    This case of Cogan's syndrome is unusual in the following points; 1) The rather long interval between the onset of eye and vestibuloauditory symptoms, 2) old age, 3) caloric test which showed directional preponderance to the right and 4) unilateral keratitis.
    This case has showed no signs and symptoms of systemic disease such as periarteritis nodosa, though she had hypertension and kidney disease in the past. With the increase of the cases, some variations in the signs and symptoms of this syndrome have been appearing. These may be also called as Cogan's syndrome or atypical Cogan's syndrome for the time being, since the etiologic factors not yet been discovered. But in the future we should analyse and classify the case from the etiological point of view.

    Three cases of otogenous lateral sinus thrombosis were recored at the Oto-laryngological Department of Okayame University Medical School, during 1962.
    Although the introduction of sulfonamide or antibiotics has made remarkable reduction in the emergence of thrombosis or other otogenous intracranial complications, it seems that recently those complications are again becoming common.
    The latest characteristic trends of these cases as follows: 1) In the majority of the cases, these complications were derived from the chronic stage of middle ear infection. 2) Misuse of the chemotherapy masks the early signs and there is difficulty of the diagnosis at the first stage of otogenous thrombosis or others. 3) Formerly, the causative germ was hemolytic staphylococcus, but recently, staphylococcus aureus and pyocyaneus have been found prevalent.
    When the patient is suspected of having an intracranial affection, surgery and following suitable chemotherapy is the accepted method of treatment.

    Roentgenograms of 30 cases of the operated maxillary cancer are compared with the histological findings in the large section preparates. Results as follows:
    1) The maxillary sinus. The dense shadows with the bright portions and discontinuous contours of the sinus walls are the pathogmotical findings. The destruction of the posterior wall and the pterygoid process are visualized by means of the axial views, Rhese's technic and horizontal or sagittal tomography.
    2) The almost similar findings are found in the ethmoid portion.
    3) The sphenoidal sinus has to be examined by means of the axial views and the frontal tomography.
    4) The dense shadows sometimes were found in the frontal sinus, but no invasion of the cancer in this series.
    5) The nasolacrimal duct was visualized through the injection of 40% moljodol (0.3cc). Its abnormality revealed the invasion of the cancer in the anterior superior portion of the nasal cavity.
    6) The arteriography of the external carotid reveals the destruction of the bony walls according to the dislocation of the stem and its branches.
    The existence of the cancer in the maxillary sinus today is easily diagnosed, but the destruction of the bony wall and its grade may be only demonstrated through the adequate technic according to each wall of the sinus, so that the necessary and complete diagnosis will be only successful by means of some films, taken by adequate technics to the cases.

    Studies on the effect of oxygen consumption on the cochlea of guinea pigs exposed to powerful stimnlatins of 500cps and 1000cps pure tone (100db, 10-180 minutes.) were performed.
    Oxygen consumption of the cochlea of guinea pigs was measured by means of Warburg manometer, immediately after the cochlea was taken out.
    The results were as follows:
    1) Oxygen consumption of the cochlea increased in the cases exposed to stimmulation for 10-90 minutes, but decreased in those exposed to stimmulation for 90-180 minutes.
    2) There is no significant difference of oxygen consumption of the cochlea between the cases used of succinate as substrate and those of glucose.
    3) Following to the exposure to 500cps stimmulation (at 100db, for 30-60 minutes), oxygen consumption of the cochlea increased for three days, then decreased for 4-12 days after the stimulation. It recovered after two weeks.

    Histoanato amical structure of the vocal muscles of human adults was investigated and the sensory nerve endings in the vocal muscle were demonstrated by using various staining techniques.
    According to Goerttler (1950), medial part of the vocal cord consists of two parts, namely, pars thyreovocalis and pars aryvocalis. However, we could not find the muscle fibres which ran from the thyroid cartilage to the vocal ligament. Pars aryvocalis could be divided into the anterior and the posterior parts. The former beginning from the Proc. vocalis of the arytenoid cartilage attached to anterior half of the vocal ligament. The latter ran between middle part of the arytenoid cartilage, and posterior half of the vocal ligament. These two parts crossed each other like a network.
    Three types of the centripetal nerve endings in the vocal muscle were identified with the modified Bielschowsky's silber impregnation.
    The nerve belonging to the first type ended in a simple small knob. The nerve of the second type had spiral structure which wound about the muscle fibre like a tendril, and it seemed to be resembled to a muscle spindle, but it was not a muscle spindle. It was not enclosed with a capsule and did not contain intrafusal muscle fibres. The typical muscle spindles were not found in the human vocal muscle. The nerve belonging to the third type consisted of several nerve fibres which ran pararell each other like an ivy.
    The great majority of these endings were distributed in the middle one-third of the vocal cords. No communicative fibres between these endings and the endformation of the autonomic nervous system were recognized. The nature and significance of these stuctures were discussed.
