花椒刺激你的「觸覺」!?

將文章推到Google Buzz
說到美食,總強調「色」、「香」、「味」俱全,然而除了視覺、嗅覺、味覺,「觸覺」也是重要的環節。台灣人鍾愛的QQ口感是一個例子,但你知道花椒的「麻」,也是透過刺激觸覺而來?



最新的神經科學研究發現,「麻」的感覺和觸覺由類似的機制產生。花椒以等同於50赫茲的震動,刺激舌頭和嘴唇上的RA1神經。這類神經特別針對輕微的觸碰和震動進行反應,例如,它能夠幫助你分辨觸摸的材質是絲質還是丹寧布。透過此研究,科學家也發現這一類神經不僅對物理刺激反應,也接受化學刺激。 花椒的「麻」就是其成分「hydroxyl-α-sanshool」,以化學的方式刺激RA1神經而來。此研究不只能幫助我們了解觸覺,也提供一個新的方向了解慢性疼痛病患長期經歷的刺麻感。

Strangers In A Strange Land

將文章推到Google Buzz
by Alva Noë

“No man is an island, complete unto itself.”
Remarkably, that is exactly what most contemporary cognitive scientists — students of consciousness and cognition, whether in neuroscience, psychology, artificial intelligence, or philosophy — are now inclined to assume.

[TSC] Brain, Mind and Reality - May 2-8, 2011 - Stockholm University - Sweden

將文章推到Google Buzz


Toward a Science of Consciousness is an interdisciplinary conference emphasizing broad and rigorous approaches to the study of conscious awareness. Topical areas include neuroscience, philosophy, psychology, biology, quantum physics, meditation and altered states, machine consciousness, culture and experiential phenomenology. Held annually since 1994, the conference is organized by the Center for Consciousness Studies at the University of Arizona, and alternates yearly between Tucson, Arizona and various locations around the world. Toward a Science of Consciousness 2011 will be held at Stockholm University, Aula Magna Hall, Stockholm, Sweden, May 2-8, 2011.

Sessions, Themes and Speakers
Dates and Times TBA
1. Brain fields and consciousness: Evidence suggests brain-generated electromagnetic fields provide feedback on brain neuronal activities, bolstering long-standing electromagnetic field theories of consciousness.

David McCormick, Yale, Brain electric field feedback
Johnjoe McFadden, Surrey, Electromagnetic field theory of consciousness
Sue Pockett, Auckland, E-M field theory of consciousness
TBA
2. Consciousness in the universe: Is consciousness an epiphenomenal happenstance of this one particular universe among multitudes, as proposed in M-theory by Hawking and Mlodinow? Or are consciousness and intelligence intrinsic to the fabric of reality?
Deepak Chopra, Chopra Foundation, Vedic approaches to consciousness and reality
Leonard Mlodinow, CalTech, Grand Design (with Stephen Hawking)
Paola Zizzi, Padua, Consciousness in the early universe.
TBA

3. Transcranial therapy of mental states:
New therapeutic modalities based on brain stimulation aimed at conscious mental disorders include transcranial electric and magnetic fields and ultrasound vibrations. Mechanisms and utility in relation to consciousness and memory will be discussed.

Allan Snyder, Sydney, Transcranial electric fields for memory enhancement
W. Jamie Tyler, Arizona State, Transcranial ultrasound for mental disorders
Eric Wassermann, NIH, Transcranial magnetic stimulation for depression
TBA
4. Time, precognition and consciousness: The famous Libet experiments and parapsychology have long suggested backward time referral of subjective conscious experience of hundreds of milliseconds in the brain. Now such effects are unexpectedly seen in mainstream neuroscience. Can they be explained through quantum physics?

Dick Bierman, Amsterdam, Pre-sentiment
Moran Cerf, NYU/UCLA, Pre-cognition in human brain neurons?
Sara Gonzalez Andino, Geneva, Backward time referral in monkey amygdala
TBA

5. Anesthesia and consciousness: Anesthetic gases selectively erase consciousness and block high frequency gamma synchrony EEG while sparing non-conscious brain functions, acting by weak quantum forces in a distributed array of post-synaptic proteins

Nicholas Franks, Imperial College London, Anesthetic sites of action
Stuart Hameroff, Arizona, Hydrophobic quantum pockets in dendritic proteins
Anthony Hudetz, MC Wisconsin, Anesthetics and gamma synchrony
TBA

6. Quantum biology: The role of quantum physics in consciousness has been discounted by the assumption that the biological brain is too warm and wet. But quantum coherence, entanglement and ballistic conductance have now been recognized in warm photosynthesis, DNA and microtubules.

Anirban Bandyopadhyay, Tsukuba, Ballistic conductance and quantum bits in microtubules
Jack Tuszynski, Alberta, Microtubule information processing capabilities
TBA

7. Neuronal activities and consciousness: Large scale coherence potentials, neuronal ignitions and avalanches correlate with consciousness. How is coherence mediated? What roles do dendritic synchrony, axonal firings, macroscopic fields, complexity and intraneuronal processes play in consciousness? Will mapping brain connections help explain consciousness?

Germund Hesslow, Lund, Complex spike timing
Rafi Malach, Weizmann Institute, Neuronal ignitions
Dietmar Plenz, NIH, Neuronal avalanches, coherence and criticality
TBA

8. Consciousness, reality and the universe: Does the conscious observer collapse the wave function? Is consciousness an emergent property of complex computation, or irreducible and intrinsically related to spacetime geometry? How did the universe arise from nothingness? What is entanglement?

Menas Kafatos, Chapman University, The holographic universe
Tarja Kallio-Tamminen, Helsinki, Quantum physics and Eastern philosophy
Paavo Pylkkanen, Helsinki, Bohm and the quantum universe
TBA

9. End-of-life brain activity: Recent clinical studies report a surge of coherent, high frequency EEG at the time of human death, when neuronal metabolic supplies are depleted. Historically, nearly all civilizations have reported so-called near death experiences with remarkably consistent phenomenology. Have brain monitors captured the correlate of near death experiences?

Lakhmir Chawla, George Washington, End-of-life brain activity
Peter Fenwick, London, End-of-life conscious experience
Pim von Lommel, Arnhem, Near death experiences
TBA
10. The varieties of religious experience: Since William James, meaning, values, intentionality, feelings and imagery related to religious experience have been part of consciousness studies. Modern imaging reveals brain regions active during religious experience, and sacramental plants are used to promote spiritual states 
Mario Beauregard, Montreal, Neuroscience of transcendent experience
Padrinho Paulo Roberto, Rio de Janeiro, Sacramental plants of Amazonia and religious experience
TBA

In addition to Keynote and Plenary talks, the conference will feature Pre-Conference Workshops, Concurrent Talks, Poster Sessions, Art/Tech Demos, Social Events and Side Trips in the Stockholm tradition.

Special Pre-Conference Workshop  -   full day 
Monday May 2, 2011 - registration - TBA

2010知覺與自我意識跨領域研討會

將文章推到Google Buzz
議程:www.ee.ntu.edu.tw/eeoffice/download/News/101018142402.pdf

http://www.philo.ntu.edu.tw/ann/view.php?ID=753

時間:2010年10月25日至26日

地點:臺灣大學生命科學館三樓演講廳

主辦單位:台灣大學哲學系
政治大學心腦與學習研究中心
陽明大學心智哲學研究所



近年來心智哲學的一個重要主題是關於知覺意識與自我意識之間的關係。包括:(1)知覺意識(perceptual consciousness)與自我意識(self-consciousness)的關係是什麼?知覺意識提供了對於外在世界之感覺性的(sensory)且立即的識察(awareness),自我意識則使得認知者以某種方式意識到自己。這兩種意識是否根本上是彼此獨立的,還是說兩者在本質上有密切關聯?更具體而言,如果要對知覺經驗的特性有完整的說明,是否必須訴諸於某種特定的自我意識才行?(2)根據Shoemaker所提出的第一人稱「識別錯誤之免疫性」(“the immunity to error through misidentification”),關於經驗的內容(content),我們可能會弄錯(如:眼前鏡子裏的那個人是不是我?我現在到底是覺得痛,還是覺得癢?) 但是對於辨識自己是否為該經驗的當事者(subject),我們絕不會弄錯。這種immunity是不是自我意識的根本性質之一?(3)要擁有自我意識是否需要具備複雜的概念能力?對於知覺的現象特性(phenomenal character)的經歷能否完全不涉及任何自我意識?(4)假設知覺與自我意識有本質上的關聯,那麼這兩者究竟是以什麼方式關聯在一起?那一個理論能對此提供最好的解釋?

有鑑於此,台灣大學哲學系、政治大學心腦與學習研究中心與陽明大學心智哲學研究所於2010年10月25、26日舉辦「知覺與自我意識跨領域研討會」。此次研討會目的在探討知覺意識(perceptual consciousness)與自我意識(self-consciousness)的關係。台灣大學哲學系邏輯心靈與方法論研究團隊成員目前的研究認為,對腦傷病人的各種現象(phenomenology)和腦部神經活動進行第一手的研究,以及藉由實驗操控視覺與身體感覺之間的關係,會幫助本研究小組在關於知覺與自我意識的哲學議題上有所突破。此次研討會主要是以邀請國外學者,為目前最為先進的哲學發展,就有關知覺與自我意識中最先進的研究與實驗,提出一具體而且明確的討論說明。召開本研討會的策略,在於集結世界各地針對知覺與自我意識的研究人才,透過本研究小組成員之邀請,專程來台參與討論。

本研討會以兩天舉行,共計七場討論。廣邀國內外學有專精的學者發表最新論文(國內3篇,國外4篇),批判對話討論。除了能夠提昇國內相關領域的研究發展之外,也將是一次與校內其他研究領域(例如心理系、醫學系、神經醫學研究)重要的科際整合。

New York Times: Sizing Up Consciousness by Its Bits

將文章推到Google Buzz

SCIENCE   | September 21, 2010
By CARL ZIMMER Researchers want to build a meter that can measure consciousness as easily as body temperature.
The anesthesiologist was preparing to give Dr. Tononi one drug to render him unconscious, and another one to block muscle movements. Dr. Tononi suggested the anesthesiologist first tie a band around his arm to keep out the muscle-blocking drug. The anesthesiologist could then ask Dr. Tononi to lift his finger from time to time, so they could mark the moment he lost awareness...

* 04 May 2010 by David Wolman

MICHELLE Dawson can't handle crowded bus journeys, and she struggles to order a cup of coffee in a restaurant because contact with strangers makes her feel panicky. Yet over the past few years, Dawson has been making a name for herself as a researcher at the Rivière-des-Prairies hospital, part of the University of Montreal in Canada.

[新聞]瀕死經驗是腦子最後一次放電

美國一個醫生說,瀕死經驗實際上是腦子在死前最後一次放電。
    
美國喬治華盛頓大學附屬醫院加護病房醫生朝拉說,為了知道開給病人的止痛藥是不是管用,他監測了七名病重病人的腦波。他說,病人撒手人寰以前一個小時,原本微弱的腦波會有一段時間特別活躍。時間長短不一,最短的有三十秒,最長的有三分鐘。
