This paper reviews the structural specificities and functional roles in Brodmann areas 10 and 38. A number of studies have focused on both areas through various approaches including neuropsychology, neuroimaging, psychiatry, neurology, and neurosurgery. Both areas 10 and 38 may have a substantially very complex higher-order cognitive functions, which are quite hard to disentangle. Here, I picked up some fundamental perspectives for reviewing previous studies, to provide efficient research orientations for the elucidation of functions in both areas.

Although a number of studies have investigated the incongruity-detection and resolution process in humor comprehension, it is difficult to functionally and anatomically dissociate these processes. We used event-related potentials (ERP) and standardized low resolution brain electromagnetic tomography analysis (sLORETA) to examine the time course and localization of brain activity during incongruity detection and resolution. We used the same materials as in our previous fMRI study. Eighteen participants read funny and unfunny scenarios and judged whether the target sentence was funny or not. Results indicated that ERPs elicited by a funny punch line showed a P2 component followed by a P600 component over the centro-parietal electrode sites. Our sLORETA analysis of the P2 ERPs revealed a stronger activation for the funny vs. unfunny condition in the superior frontal gyrus (SFG) and medial prefrontal cortex (mPFC). For the P600 ERPs, the funny punch line elicited greater activation in the temporal-parietal regions. These results indicate that incongruity-detection processes activate the SFG and mPFC in the P2 time window, while incongruity-resolution processes generate activation at the temporal-parietal regions in the P600 time window. These results provide the evidence that verbal humor comprehension is processed in steps which start with the incongruity detection in the early P2 time window and followed by a P600 component reflecting incongruity resolution.

Explicit interoceptive awareness in emotional situation

Tanaka Yuto, Ito Yuichi, Shibata Midori, Terasawa Yuri, Umeda Satoshi

Proceedings of the Japanese Society for Cognitive Psychology (The Japanese Society for Cognitive Psychology) 2017 111 - 111 2017

嫌悪，恐怖，喜びといった情動の生起には，自律神経反応が伴っている。情動によって生じる自律神経反応は意識的に感じられることがあり，自律神経反応を含めた身体内部の状態の知覚は内受容感覚と呼ばれている。本研究では，内受容感覚の意識的な感じやすさが，情動の種類あるいは性格傾向の違いによって異なるのかを検討した。参加者は嫌悪，恐怖，喜びを喚起させる画像を見たときに，自身の身体に変化が生じたかを答えた。内受容感覚を知覚できた刺激の数は嫌悪の情動が最も多く，次いで恐怖，喜びの順番であった。また，アレキシサイミア傾向が高い人は，恐怖の情動に対して身体の変化を感じにくく，状態不安の高い人は，喜びの情動に対し，身体の変化を意識的に知覚しやすかった。これらの結果は，意識的な内受容感覚は情動の種類によって感じやすさが異なっていること，それは性格傾向の影響も受けていることを示唆している。

Interactions of anxiety, gaze direction, and emotional expressions in the gaze-cueing paradigm

視線を手がかりとしたPosner課題を視線手がかり課題と呼び，一般に手がかり刺激の恐怖表情や観察者の高不安傾向で手がかり効果が増大するとされるが，背景には視線と表情が持つ社会的シグナルの働きがあると考えられる。本研究では接近―逃避の対照的なシグナルを持つ怒りと恐怖の表情で視線手がかり課題を行い，状態不安得点で参加者を群分けして課題成績を分析した。その結果，視線と標的の一致性，表情，不安傾向の三要因間で二次の交互作用を得た。下位検定では，一致条件による注意促進が高不安の恐怖表情で高まるが低不安では逆に怒りで高く，低不安・恐怖では促進よりも不一致での抑制効果の方が大きい等の結果を得た。本研究の結果は，恐怖表情や高不安が手がかり効果を単純に促進するのではなく，視線と表情の組合せで異なる社会的シグナル機能が観察者の性格傾向との関係で異なる影響を受け，注意誘導効果の増減となって表れることを示唆する。

Temporal Concepts in Social Anxiety and Depression Tendency:

Ito Yuichi, Terasawa Yuri, Umeda Satoshi

Proceedings of the Japanese Society for Cognitive Psychology (The Japanese Society for Cognitive Psychology) 2017 89 - 89 2017

うつ病には過去のネガティブな記憶を反芻し，不安障害 (特に社会不安) には未来の事象についてネガティブな予期をするという特徴が見られる。このことから，抑うつ傾向の高い個人は過去に，社会不安傾向の高い個人は未来に対して，相対的にネガティブな概念が形成されている可能性が考えられる。本研究では，健常者を対象に潜在連合テスト (IAT) を用いて時間概念 (過去・未来) と感情価 (ネガティブ・ポジティブ) の連合を測定し，個人差 (社会不安傾向・抑うつ傾向) との関係を検討した。その結果，基本的に未来はポジティブ，過去はネガティブという時間概念と感情価の連合が存在しており，社会不安と抑うつ傾向の高低がその連合の強さに対して交互作用的に影響することが示された。これは，うつや社会不安に特徴的な認知の歪みが，時間概念と感情価の連合関係から捉えられる可能性を示唆している。

Confidence Rating on Perception and Memory：

自身の能力についての知識であるメタ認知に関する研究において、確信度の正確性の観点からType2信号検出理論が近年注目されている。本研究では脳波を用い、知覚・記憶の二課題に対しType2信号検出理論を用いた検討を行った。実験では、知覚課題については、2つの刺激のうちより明るく見える方の位置を同定する課題を行い、記憶課題については、50単語をリストで一挙に提示したのち、再認を行った。それぞれ刺激提示時の事象関連電位とその刺激に対する確信度の関連性について検討した。結果、両課題で確信度が高いほど400ms以降特徴的な脳波成分が見られた。また記憶課題において、確信度が正確な人ほど400ms前後に特徴的な陰性成分が見られた。従って、刺激提示の段階において知覚判断に対しても記憶判断と同様の時間帯に確信度に関する処理が行なわれていること、その時間帯の処理の深さが正確性に影響していることが示唆された。

We have studied various kinds of rehabilitation method in a real life space with partner robots for higher brain dysfunction patients. This paper proposes a rehabilitation system configuration method which digitizes a real life space, reconstruct an extended augmented real space. The proposed method can construct step by step their rehabilitation according a real life human situation by coordinating a partner robot for cognitive and physical disabled patients. We focus on activities of daily life (ADL) such as clean-up task and cooking.

Prospective memory mediated by interoceptive accuracy

Umeda Satoshi, Tochizawa Saiko, Shibata Midori, Terasawa Yuri

Philosophical Transactions of the Royal Society B: Biological Sciences 371 ( 1708 ) 2016.11

ISSN 0962-8436

Previous studies on prospective memory (PM), defined as memory for future intentions, suggest that psychological stress enhances successful PM retrieval. However, the mechanisms underlying this notion remain poorly understood. We hypothesized that PM retrieval is achieved through interaction with autonomic nervous activity, which is mediated by the individual accuracy of interoceptive awareness, as measured by the heartbeat detection task. In this study, the relationship between cardiac reactivity and retrieval of delayed intentions was evaluated using the event-based PM task. Participants were required to detect PM target letters while engaged in an ongoing 2-back working memory task. The results demonstrated that individuals with higher PM task performance had a greater increase in heart rate on PM target presentation. Also, higher interoceptive perceivers showed better PM task performance. This pattern was not observed for working memory task performance. These findings suggest that cardiac afferent signals enhance PM retrieval, which is mediated by individual levels of interoceptive accuracy. This article is part of the themed issue ‘Interoception beyond homeostasis: affect, cognition and mental health’.

Emotion disorders and abnormal perspiration

Umeda Satoshi

Brain and Nerve (Igaku-Shoin Ltd) 68 ( 8 ) 893 - 901 2016.08

ISSN 1881-6096

This article reviewed the relationship between emotional disorders and abnormal perspiration. First, I focused on local brain areas related to emotional processing, and summarized the functions of the emotional network involving those local areas. Functional disorders followed by the damage in the amygdala, orbitofrontal cortex, and insular cortex were reviewed, including related abnormal perspiration. I then addressed the mechanisms of how autonomic disorders influence emotional processing. Finally, possible future directions for integrated understanding of the connection between neural activities and bodily reactions were discussed.
