By then traces of brain material would have contaminated the butchers' knives, hands, clothes, the wiping cloths, the cutting block and other parts of the carcass.
But in recent months at a clinic in Liège, Belgium, the patient, now 29, showed traces of brain activity in response to commands from doctors.
Manual tracing of brain volumes of interest was carried out in the software package MRIcron (C. Rorden, http://www.mccauslandcenter.sc.edu/mricro/mricron/), with reference to the contralesional hemisphere.
In addition, it has to be kept in mind that the quality of manual tracing of brain structures is always restricted by the actual resolution of the MRI images in our case the images were acquired in a 1.5-T Scanner and that very high inter- and intra-rater reliabilities do not indicate anatomical accuracy, but only stability of segmentation.
And the finding is particularly pertinent because existing dietary advice to pregnant women, at least in America, is that they should limit their consumption of seafood in order to avoid exposing their fetuses to trace amounts of brain-damaging methyl mercury.
In morphometric research, the traditional approach has been to trace a set of brain structures on MRI scans either manually or automatically and compute their volumes.
PKMζ, the long-term memory trace in a variety of brain regions [ 1, 61], is also found in the cerebellar cortex [ 61], suggesting its potential involvement in cerebellar LTD [ 13, 18, 62].
Because of their vigor, the spirits are likely to overflow to nearby, related traces of objects (association is here understood in terms of the proximity of brain traces), which then come along for the recollective ride.
This labelling method can be used to target small nuclei in neuronal tissue and is generally applicable to the study of functional synaptic connectivity, or live axonal tracing in a variety of brain areas.
In the case of brain traces, second-order structural resemblances hold when some physical relations among certain brain states (such as distance relations in the activation space of a neural network) preserve some system of relations among represented objects (O'Brien and Opie 2004, pp. 8 14).
