Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Intrinsically Disordered Proteins

19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Animal Mitochondrial Genetics

9.3K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Energy to Drive Translocation01:37

Energy to Drive Translocation

2.9K
Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.
Generally, polypeptides are unfolded by two distinct...

Association Areas of the Cortex01:21

Association Areas of the Cortex

9.4K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

精神病理の遺伝的リスクは、共有された横断的要因ではなく、障害特異的な経路を通じて認知と関連している。これらの独自の遺伝的影響を理解することが、精神的健康と認知機能の間の複雑な関係を解明する鍵となる。

科学分野:

  • 精神医学
  • 遺伝学
  • 認知神経科学

背景:

  • 認知機能は精神病理において重要であるが、過小評価されている。
  • 認知機能障害はしばしば診断境界を越え、障害特異的な関連を複雑にする。
  • 遺伝学的研究は、共有された（横断的な）遺伝的影響と独自の遺伝的影響を区別することができる。

研究 の 目的:

  • 精神病理の横断的および障害特異的な遺伝的リスク因子を特定すること。
  • 精神病理の遺伝的リスクが発達段階全体にわたる認知機能にどのように関連するかを調べること。

主な方法:

  • ゲノム構造方程式モデリングを使用した。
  • 多因子スコアは、縦断的な双子サンプル（N=7764）から導出された。
  • 遺伝的リスクと認知領域との関連を分析した。

主要な成果:

  • 精神病理と認知の関係は、主に障害特異的な遺伝的リスクによって駆動される。
  • 関連は、異なる障害や認知領域にわたって変動した。
  • 家族内分析により、環境要因に対して頑健なものを含む、これらの関連の異なる経路が明らかになった。

結論:

  • 障害特異的な遺伝的影響は、精神病理と認知の関連を理解するために重要である。
  • 横断的な遺伝的リスクは、認知機能よりも精神症状により関連がある。
  • 横断的なリスクのみに焦点を当てることは、精神病理における認知プロファイルの複雑さを見落としている。
