Patricia Churchland and Neuroscience

Posted by

At peace with my brain  Patricia Churchland interviewed by Graham Lawton  ::  New Scientist, 30 November 2013  ::  www.newscientist.com Summary and review of the above interview In this interview, it is apparent that the philosopher, Patricia Churchland, has moved on to occupy the neuroscience territory. As part of the group of 1990s thinkers that directed consciousness towards what some might argue to be its present cul-de-sac, in which sensible people are inhibited about discussing any Read more […]

Halothane binding proteome in human brain cortex  ::  Roderic Eckenhoff, Maryellen Eckenhoff et al, University of Pennsylvania  ::  Journal of Proteome Research, 2007, 6, pp. 582-592  ::  http://pubs.acs.org/doi/pdf/10.1021/pr060311u Summary and review of the above paper This later study demonstrated that anaesthetics could interact with many human brain proteins; previous studies has been confined to rodent brains. Recent research has expanded rather than contracted the potential targets Read more […]

Inhalational anaesthetic-binding proteins in neuronal membrane Jin Xi, Maryellen Eckenhoff, Roderic Eckenhoff et al, University of Pennsylvania & Amersham Biosciences  ::  The Journal of Biological Chemistry, Vol. 279, No. 19, May 7 2004, pp. 19628-19633  :: http://www.jbc.org/content/279/19/19628.full.pdf+html Summary and review of the above paper In this study 34 binding sites were identified for the anaesthetic halothane. Within this group, mitochondrial proteins especially those Read more […]

Anaesthetics act in quantum channels in brain microtubules to prevent consciousness Travis Craddock, Stuart Hammerof, Jack Tuszynski et al, Nova Southeastern University, University of Alberta  ::  www.benthamscience.com/journal/ Summary and review of the above paper INTRODUCTION:  Recent research into the binding of anaesthetic molecules looks to revive the idea of hydrophobic pockets in the microtubules of neurons as the most suitable binding site for anaesthetic molecules. This could Read more […]

Quantum criticality at the origin of life  ::  Gabor Vattay, Stuart Kaufmann et al, Eotvos University, University of Calgary and University of Toronto  ::  arXiv:1502.06880v2 [cond-mat.dis-nn] 3 Mar 2015 Summary and review of the above paper Most biomolecules are suggested to be neither conductors nor insulators, but to be at the critical transition point between these states. In this respect, they are seen as being a special type of quantum-critical material. Molecules involved in biochemical Read more […]

Towards a sublime state of consciousness  ::  Raymond McBride  ::  Journal of Consciousness Studies, No. 11-12, 2014, pp. 19-40  ::  www.imprint.co.uk/jcs.html Summary and review of the above paper Focused attention and mental absorption, to the exclusion of other sensory inputs, are seen as catalysing altered states of consciousness. The author discusses meditation; some research on meditation suggests that blood flow to brain regions involved in directing attention decreases during Read more […]

Free choice

Decoding intention at sensorimotor timescales Matthew Salvaris & Patrick Haggard  ::  PLOS one, February 11 2014, DOI: 10.137/journal.pone.0085100  ::  http://www.plosone.org/ Summary and review of the above paper This paper examines the difference between the neural processing of small motor actions such as pressing a button, when the action follows on an external instruction, and alternatively when it is seen as the free choice of the subject. This follows the Libet tradition of Read more […]
