Sasabayashi D, Tsugawa S, Nakajima S, Takahashi T, Takayanagi Y, Koike S, et al.
Prog Neuropsychopharmacol Biol Psychiatry . 2024 Nov; 136():111197. PMID: 39579961
An anomalous pattern of structural covariance has been reported in schizophrenia, which has been suggested to represent connectome changes during brain maturation and neuroprogressive processes. It remains unclear whether similar...

Torigoe M, Takahashi T, Takayanagi Y, Sasabayahi D, Kobayashi H, Sakamoto K, et al.
Front Psychiatry . 2024 May; 15:1368681. PMID: 38721613
Introduction: The findings of epidemiological studies suggest that a relationship exists between the risk of schizophrenia and winter births in the Northern Hemisphere, which may affect the process of fetal...

Kobayashi H, Sasabayashi D, Takahashi T, Furuichi A, Kido M, Takayanagi Y, et al.
Cereb Cortex . 2024 Jan; 34(2). PMID: 38265871
Previous postmortem brain studies have revealed disturbed myelination in the intracortical regions in patients with schizophrenia, possibly reflecting anomalous brain maturational processes. However, it currently remains unclear whether this anomalous...

Takahashi T, Sasabayashi D, Takayanagi Y, Kobayashi H, Torigoe M, Sakamoto K, et al.
Psychiatry Res Neuroimaging . 2023 Sep; 335:111714. PMID: 37690160
This MRI study examined the effects of birth seasons on gross brain characteristics, such as the prevalence/size of midline brain structures (cavum septi pellucidi and adhesio interthalamica), orbitofrontal surface morphology,...

Takahashi T, Sasabayashi D, Takayanagi Y, Furuichi A, Kobayashi H, Yuasa Y, et al.
Schizophr Res . 2023 Aug; 260:23-29. PMID: 37549494
Background: Magnetic resonance imaging (MRI) studies have revealed gray matter reductions in the insular cortex of schizophrenia patients. Despite large inter-individual anatomical variations in the insular gyri of human brains,...

Takahashi T, Sasabayashi D, Takayanagi Y, Higuchi Y, Mizukami Y, Akasaki Y, et al.
Front Psychiatry . 2023 Jul; 14:1192854. PMID: 37476540
Introduction: Since the number of insular gyri is higher in schizophrenia patients, it has potential as a marker of early neurodevelopmental deviations. However, it currently remains unknown whether the features...

Sasabayashi D, Takahashi T, Takayanagi Y, Nemoto K, Ueno M, Furuichi A, et al.
Cereb Cortex . 2023 Apr; 33(13):8456-8464. PMID: 37099431
Disrupted functional connectivity (FC) of the default mode network (DMN) may have a pathophysiological role in schizophrenia. However, functional magnetic resonance imaging (fMRI) of the DMN in schizophrenia patients has...

Takahashi T, Sasabayashi D, Takayanagi Y, Furuichi A, Kobayashi H, Yuasa Y, et al.
Front Psychiatry . 2022 Dec; 13:1050712. PMID: 36465304
Introduction: Patients with schizophrenia have a higher number of insular gyri; however, it currently remains unclear whether the brain characteristics of patients with schizotypal personality disorder (SPD), a mild form...

Sasabayashi D, Takayanagi Y, Takahashi T, Furuichi A, Kobayashi H, Noguchi K, et al.
Front Psychiatry . 2022 Aug; 13:937605. PMID: 36032231
Most schizophrenia patients experience psychotic relapses, which may compromise long-term outcome. However, it is difficult to objectively assess the actual risk of relapse for each patient as the biological changes...

Front Psychiatry . 2022 Jul; 13:867461. PMID: 35782454
Deficit syndrome schizophrenia is a characteristic subtype defined by persistent negative symptoms and poor functional outcomes; however, the biological mechanisms underlying this specific subtype have not yet been elucidated in...
