Coherent energy transfer

Posted by

The feasibility of coherent energy transfer in microtubules Travis Craddock et al, Nova Southeastern University http://arxiv.org/abs/1405.3170 Summary and review of the above paper INTRODUCTION:  Craddock’s paper emphasises the strong similarities between tryptophan complexes in microtubules and quantum coherent energy transfer in photosynthesis, a connection which is dumbed out in most discussions of quantum biology. The microtubules are themselves closely connected to mitochondria; Read more […]

Hierarchical competitions subserving multi-attribute choice Lawrence Hunt, Raymond Dolan, Timothy Behrens, University College London, University of Oxford Nature Neuroscience, Vol. 17, No. 11, November 2014 www.nature.com/neuro Summary and review of the above paper In decision neuroscience, the different attributes of competing possible options are assumed to be assimilated into unitary values. This system has the advantage of allowing comparison of incommensurable items. The authors argue Read more […]

Conscious alteration of emotional processing

Posted by

Orthodox theories are not successful in explaining the causal interaction between mental experiences and events in the brain. Since the year 2000, neuroimaging studies have shown that the activity of brain regions involved in emotional processing can be consciously and volitionally altered. This paper seeks to demonstrate the causal influence of such phenomena as thoughts, on the brain, and on subsequent behaviour. Thus beliefs, goals and expectations are seen as being related to behaviour.

Anterior insula and epilepsy

Posted by

Summarises an article by Anil Ananthaswamy, New Scientist, 25 January 2014 This article looks at the effect of a particular type of epileptic seizure on the anterior insula region of the brain. There are two main types of epileptic seizure; general seizures effect the whole of the cortex; this article refers to the other main type of seizure, focal or partial seizures concentrated in small regions of the brain, which is rarer than general seizure. There is also a suggestion that the stranger effects Read more […]

By Harlan M. Fichtenholtz & Kevin S. Labar, YaleUniversity and DukeUniversity. Published In:-  The Neuroscience of Attention Ed. George R. Mangun, Oxford University Press (2012) Summary and review of the above chapter INTRODUCTION:-  Attention and emotion are argued to be parallel processes interacting at many stages in the brain. Some brain regions are more involved with emotional response and others more with attentional control. Limbic regions act so as to bias sensory processing, Read more […]

Taming the quanta

Posted by

Taming the Quanta Martin Plenio, Imperial College London Lecture to the Royal Society, 14 October 2008 Martin Plenio’s lecture of October 14 2008 has provided an interesting footnote to the Engel paper reviewed immediately above. In photosynthesis, the chlorophyll molecule is 98% efficient in transporting energy. Energy is absorbed in the form of light. The molecule supports excitation and oscillation of electrons, and allows the exploration of pathways in the molecule. A classical system Read more […]
