NEURAL PLASTICITY 2015

Language：English Publisher：HINDAWI PUBLISHING CORPORATION

Early loss of one sensory system can cause improved function of other sensory systems. However, both the time course and neuronal mechanism of cross-modal plasticity remain elusive. Recent study using functional MRI in humans suggests a role of the prefrontal cortex (PFC) in cross-modal plasticity. Since this phenomenon is assumed to be associated with altered GABAergic inhibition in the PFC, we have tested the hypothesis that early postnatal sensory deprivation causes the changes of inhibitory neuronal circuit in different regions of the PFC of the mice. We determined the effects of sensory deprivation from birth to postnatal day 28 (P28) or P58 on the density of parvalbumin (PV), calbindin (CB), and calretinin (CR) neurons in the prelimbic, infralimbic, and dorsal anterior cingulate cortices. The density of PV and CB neurons was significantly increased in layer 5/6 (L5/6). Moreover, the density of CR neurons was higher in L2/3 in sensory deprived mice compared to intact mice. These changes were more prominent at P56 than at P28. These results suggest that long-term sensory deprivation causes the changes of intracortical inhibitory networks in the PFC and the changes of inhibitory networks in the PFC may contribute to cross-modal plasticity.

Factors predicting psychiatric co-morbidity in gender-dysphoric adults

PSYCHIATRY RESEARCH 200 ( 2-3 ) 469 - 474 2012.12

Language：English Publisher：ELSEVIER IRELAND LTD

Persons with gender identity disorder (GID) often suffer from psychiatric co-morbidity, and it is an important prognostic factor for long-term psychosocial adjustment in GID. However, previous research has not addressed the risk factors of psychiatric co-morbidity. In this study, we tried to clarify the risk factors among individuals with GID in Japan. A total of 326 consecutive GID persons were evaluated independently by two senior psychiatrists at the GID clinic using personal clinical interviews and results of examinations. The prevalence of current psychiatric co-morbidity was 17.8% of the total sample. School refusal was significantly associated with psychiatric co-morbidity. Sexual attraction to neither males nor females among GID persons and sexual attraction to females among male-to-female (MtF) GID persons were also significantly related to psychiatric co-morbidity. This is the first report to demonstrate a close relationship between patterns of sexual orientation and psychiatric co-morbidity among GID persons. We should pay more attention to psychiatric co-morbidity, especially among GID persons with non-homosexual sexual orientations. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

School refusal by patients with gender identity disorder

Seishi Terada, Yosuke Matsumoto, Toshiki Sato, Nobuyuki Okabe, Yuki Kishimoto, Yosuke Uchitomi

GENERAL HOSPITAL PSYCHIATRY 34 ( 3 ) 299 - 303 2012.5

Language：English Publisher：ELSEVIER SCIENCE INC

Objective: The accumulating evidence suggests that school refusal behavior is associated with severe negative outcomes. However, previous research has not addressed school refusal by patients with gender identity disorder (GID). In this study, we tried to clarify the prevalence of school refusal among GID patients and the relationship of school refusal to demographic characteristics.
Methods: A total of 579 consecutive Japanese GID patients at the outpatient GID Clinic of Okayama University Hospital between April 1997 and October 2005 were evaluated.
Results: The prevalence of school refusal was 29.2% of the total sample. School refusal was more frequent among GID patients with divorced parents than those with intact families. Multiple logistic regression analysis showed that younger age at consultation and divorce of parents were significantly associated with school refusal among the male-to-female GID patients.
Conclusion: The rate of school refusal among GID patients is high, and school refusal is closely related with a low level of education and current unemployment. We should pay more attention to GID patients of school age to prevent their school refusal, which results in low educational achievement. (C) 2012 Elsevier Inc. All rights reserved.

Attenuated Sensory Deprivation-induced Changes of Parvalbumin Neuron Density in the Barrel Cortex of Fc gamma RIIB-deficient Mice

ACTA MEDICA OKAYAMA 66 ( 2 ) 143 - 154 2012.4

Language：English Publisher：OKAYAMA UNIV MED SCHOOL

Recent studies have demonstrated the important role of immune molecules in the development of neuronal circuitry and synaptic plasticity. We have detected the presence of Fc gamma RIIB protein in parvalbumin-containing inhibitory interneurons (PV neurons). In the present study, we examined the appearance of PV neurons in the barrel cortex and the effect of sensory deprivation in Fc gamma RIIB-deficient mice (Fc gamma RIIB-/-) and wild-type mice. There was no substantial difference in the appearance of PV neurons in the developing barrel cortex between Fc gamma RIIB-/- and wild-type mice. Sensory deprivation from immediately after birth (PO) or P7 to P12-P14 induced an increase in PV neurons. In contrast, sensory deprivation from P7 or P14 to P28, but not from P21 to P28, decreased PV neurons in wild-type mice. However, sensory deprivation from PO or P7 to P12-P14 did not increase PV neurons and sensory deprivation from P7 or P14 to P28 did not decrease or only modestly decreased PV neurons in Fc gamma RIIB-/- mice. The results indicate that expression of PV is regulated by sensory experience and the second and third postnatal weeks are a sensitive period for sensory deprivation, and suggest that Fc gamma RIIB contributes to sensory experience-regulated expression of PV.
