Reflections on the Pathology of the Brain

Philosophical reflections on therapeutic brain stimulation

Neurostimulation techniques have contributed to neural models of motor, cognitive, affective and volitional functions by elucidating their biophysical underpinning. Deep brain stimulation (DBS) is particularly significant in this regard because it can both probe and modulate activity in dysfunctional neural circuits in patients with neurological and psychiatric disorders (Lozano and Lipsman, 20...

Brain reflections of words and their meaning.

The neurobiological organization of meaningful language units, morphemes and words, has been illuminated by recent metabolic and neurophysiological imaging studies. When humans process words from different categories, sets of cortical areas become active differentially. The meaning of a word, more precisely aspects of its reference, may be crucial for determining which set of cortical areas is ...

Reflections on the interaction of the mind and brain.

Problems associated with the topic of the mind-brain interaction are reviewed and analyzed. If there is an interaction, then the "mind" and "brain" are independent variables; the mind represents subjective experience and is therefore a non-physical phenomenon. This fact led to the need for a field theory, termed here the "cerebral mental field" (CMF). By definition, the CMF is a system property...

Interpreting brain images – reflections on an adolescent field

Functional brain imaging is maturing, but still adolescent. It has developed a rich toolbox of experimental and data analytical techniques and is addressing an ever expanding range of questions about brain and mind – at various levels of methodological rigor. Some of these questions (e.g. romantic love) are difficult to pin down with science. Occasionally results are naively overinterpreted in ...
