Grey matters
It is partly by research on the sensory capabilities of other organisms that we realise just how visual humans are. We have abandoned many of the senses other species possess. We can't smell our way up a pheromone-laden path, detect magnetic fields or electrical potentials, our brains contain no compasses by which we can navigate vast distances. The masses of nerve cells required for these skil...
متن کاملGrey Matters: From Biochemical Synapse to Bioethical Syntax
The synapse is a specialized junction through which neurons ? the brain?s fundamental cellular units ? signal other cells. An examination of patterns of neural transmission at the synapse provides an interesting small-scale paradigm for considering principles of effective and ineffective communication among and within human communities. Following a general description of the synapse, this essay...
متن کاملMorphological Differences in the Grey Matters of Mathematicians: A Voxel-Based Morphometry Study
INTRODUCTION: Use-dependent cortical plasticity has been the subject of some previous studies [1], [2]. However, there is not any study on the structural changes due to the academic occupation of mathematicians. Voxel Based Morphometry (VBM) permits us to make a voxel-based comparison of the local concentration of grey matter between two groups. In this study, we present a preliminary result of...

متن کاملGREY MATTERS Ethical considerations in functional magnetic resonance imaging research in acutely comatose patients
Estimating the likelihood of recovery of cognitive function in the acutely comatose patient is one of the most difficult challenges facing neurologists and critical care physicians. Coma, defined as a state of unarousable unconsciousness, is most commonly caused by traumatic brain injury and anoxia following cardiopulmonary arrest. Patient outcome after severe brain injury is highly variable (Y...
