第22回 人間系コロキアム(1/22/2016)のご案内

筑波大学人間系研究戦略委員会では、活動の一環として平成24年度より「人間系コロキアム」を開催しています。国内・外からの招聘講師による講演に加えて、人間系所属教員による講演を企画し、人間系所属教員を中核とした領域横断的研究の更なる推進を目指しております。   27年度第7回目の開催となる本コロキアムでは、人間系心理学域教員のパブリデス・コンスタンチン先生による講演会を予定しています。教員、大学院・学類学生の他、広く多くの方々のご参加をお待ちしております。

日  時:  2016年1月22日(金)16:00~     

場  所:  筑波大学  人間系学系棟B532

タイトル:「To Slumber, Perchance to Remember」
                
講演内容:
We spend a third of our lives sleeping. What are possible reasons for this? Although sleep may serve many physiological functions (e.g., homeostasis - energy conservation, restoration, regeneration), it has also been hypothesized to play a crucial role in memory consolidation.  Much of the evidence for this, however, has been ‘soft’ or correlational: dreaming; sleep deprivation induced memory deficits;  etc.  Recently, more concrete evidence in support of memory consolidation in sleep has been obtained.  This includes electrophysiological (both field potential and single unit recordings), brain imaging as well as molecular studies. 

It has been known for a long time that the brain is not at rest in sleep. This is true not only for brain nuclei involved in sleep itself but other regions as well, including hippocampus and neocortex.  Possible functions for the enhanced neuronal activity, however, are not clear.  Perhaps the first ‘hard’ evidence for memory consolidation in sleep was the discovery of ‘neuronal re-activation’ (Pavlides and Winson, J Neurosci 9: 2907–2918, 1989).  That is, neuronal populations active in learning during the awake state become re-activated again in sleep.  This points to a memory consolidation role for sleep.  Further evidence includes molecular studies showing that various genes become activated in sleep following awake learning (Ribeiro, S., et al. Learn Mem 6: 500–508, 1999). The lecture will go over some of this evidence and ongoing research projects in the lab.
