  • Low blood concentration of alcohol enhances activity related to stopping failure in the right inferior frontal cortex.

    Jun Shinozaki, Hiroshi Matsumoto, Hidekazu Saito, Takashi Murahara, Hiroshi Nagahama, Yuuki Sakurai, Takashi Nagamine

    Cerebral cortex (New York, N.Y. : 1991) ( Oxford University Press )  34 ( 3 )  2024.03  [Refereed]  [International journal]

    　View Summary

    ABSTRACT This study investigated the effects of low doses of alcohol, which are acceptable for driving a car, on inhibitory control and neural processing using the stop-signal task (SST) in 17 healthy right-handed social drinkers. The study employed simultaneous functional magnetic resonance imaging and electromyography (EMG) recordings to assess behavioural and neural responses under conditions of low-dose alcohol (breath-alcohol concentration of 0.15 mg/L) and placebo. The results demonstrated that even a small amount of alcohol consumption prolonged Go reaction times in the SST and modified stopping behaviour, as evidenced by a decrease in the frequency and magnitude of partial response EMG that did not result in button pressing during successful inhibitory control. Furthermore, alcohol intake enhanced neural activity during failed inhibitory responses in the right inferior frontal cortex, suggesting its potential role in behavioural adaptation following stop-signal failure. These findings suggest that even low levels of alcohol consumption within legal driving limits can greatly impact both the cognitive performance and brain activity involved in inhibiting responses. This research provides important evidence on the neurobehavioural effects of low-dose alcohol consumption, with implications for understanding the biological basis of impaired motor control and decision-making and potentially informing legal guidelines on alcohol consumption.

  • Appraisal of definition of baseline length for somatosensory evoked magnetic fields.

    Hidekazu Saito, Shogo Yazawa, Jun Shinozaki, Takashi Murahara, Hideaki Shiraishi, Masao Matsuhashi, Takashi Nagamine

    Journal of neuroscience methods ( ELSEVIER )  359   109213 - 109213  2021.05  [Refereed]  [International journal]

    　View Summary

    BACKGROUND: The baseline (BL) segment in the prestimulus period is generally assigned as a reference of evoked activities. However, an experimenter empirically defines its length in each condition. So far, the criterion for the length of a BL segment has not been established. NEW METHOD: We evaluated the effect of the length of the BL segment by recording somatosensory evoked magnetic fields (SEFs) under fixed stimulus onset asynchrony (SOA). For the evaluation of the length of the BL segment in the prestimulus period, five proportions in relation to SOA were used as the BL segment. In addition, we adopted other two types of BL segment which were the single data point measured from the value of stimulus onset (BL0) and the mean value of the whole raw data throughout the recording (DC mean). We investigated the influence of the BL segments on SEFs by utilizing two indicators: normalized N20 m amplitudes and estimated locations of corresponding equivalent current dipoles (ECDs). RESULTS: Both indicators did not show any significant differences, based on the factor of BL segments, in any SOA conditions. COMPARISON WITH EXISTING METHOD: The BL0 had by far the largest variation in the ECD locations.Therefore, utilizing stimulus onset as the BL segment should be avoided. In addition, considering that other BL segments provided comparable values by the two indicators, the DC mean can reasonably be adopted. CONCLUSIONS: We suggest that utilizing the DC mean could be employed as the BL segment.

  • Retained absolute pitch after selective amygdalohippocampectomy.

    Epilepsy & behavior reports ( ELSEVIER SCIENCE INC )  14   100378 - 100378  2020  [Refereed]  [International journal]

    　View Summary

    This study assessed the pre-operative chronic condition and effect of epilepsy surgery in a 21-year-old Japanese woman with drug-resistant right temporal lobe epilepsy (TLE). For this patient, it was crucially important to preserve language and her music capabilities, including absolute pitch (AP), which is found in the general population at less than 0.1%. The patient became seizure free, and her AP capability was preserved after selective amygdalohippocampectomy in the non-dominant right hemisphere. Most of the neuropsychological test (WAIS-III and WMS-R) scores remained in the normal range, except for low scores in verbal memory and markedly improved attention/concentration index. The patient's pre- and postoperative brain function related to language and music capabilities were investigated using functional magnetic resonance imaging (fMRI) based on two language tasks and a music task (listening to melodies). While task performance was similar in pre- and postoperative examinations, her brain activation patterns markedly differed. The most striking difference was during the music task: areas with significant activation existed in the bilateral frontal and temporal lobes before surgery, whereas postoperative activation was confined to a very limited region in the left angular gyrus. The authors speculate that the surgery triggered some change in functional organization in the brain, which contributed to preserving her capabilities.

    　View Summary

    We have previously shown that the brain functions during recognition of familiar faces (known faces) and that specific neural circuits are involved in the recognition of known faces, which are different from those of unknown faces. However, the changes in brain function during the transition from an unknown face to a known face after repeated viewing were unknown. In the present study, we conducted behavioral and MRI experiments to investigate the change from unknown faces to known faces. The results of the behavioral experiments showed that the percentage of correct responses increased and the accuracy of recall increased as the face became known. However, the MRI experiment failed to detect any change in brain function. Therefore, we suggest that the change from unknown to known faces caused a change in brain function that appeared in behavior but was not detectable by MRI.

    　View Summary

    The previous studies have shown that the 2 neural routes are important for facial recognition of strangers; the fusiform gyrus for person identity and the amygdala for facial expression. These studies have examined the face recognition of strangers, but it was unknown whether the close relatives' face was processed by the two same routes. Using functional magnetic resonance imaging (fMRI) with multi-voxel pattern analysis (MVPA), we clarified that the left fusiform gyrus is involved in both person identification and recognition of facial expressions of close relatives. Therefore, in facial recognition of close relatives, the conventional face cognitive model do not apply. We propose a new model for recognition of close relatives' face; an one route model.
