We hypothesized that MT-training leads to changes in brain structure and MT-irrelevant brain functions that involve DLPFC, which plays an important role in MT. Using morphological analyses, we could determine whether and to which locations the effects of MT-training extend beyond task-specific functional activation.
In the present experiments where agent was delivered intracerebrally, the lymphatic channels are probably irrelevant because the brain does not have significant lymphatic drainage.
One aspect relates to the modulation of the SNR in task relevant networks, another to the blocking of information processing in competing and task irrelevant networks or brain regions.
On this approach, S's knowing that P is compatible with there being "radical" (hence irrelevant) situations for example, brain-in-a-vat situations in which P would be false although S has the same experience and belief.
As far as Pat was concerned, though, to imagine that the stuff of the brain was irrelevant to the study of the mind was no more than a new, more sophisticated form of dualism.
In an article in 2005, "The Case for Mindless Economics", they argued that neuroscience could not transform economics because what goes on inside the brain is irrelevant to the discipline.
Once the attractor (or its vicinity) is reached, the "dynamical" nature of the brain becomes irrelevant; therefore, when attractors mark the terminal states of mental process, this behavior could be formulated equally effectively by an algebraic cause-response mapping.
Some authors also consider neural efficiency to reflect nonuse of brain regions irrelevant for good task performance and more focused use of specific task-relevant areas (Jausovec and Jausovec 2004b) or entirely different neural circuits (involving less prefrontal regions) in more intelligent individuals (Haier et al. 2003).
The research was published last week in Current Biology.The work adds weight to the notion that people with schizophrenia cannot filter out irrelevant information and their brains are thus being overwhelmed.
Even though feedback was not provided during these perceptual tests, it is possible that the task provides meaning/purpose to the otherwise irrelevant sound stimuli and activates brain processes that are later manifested in enhanced P2 amplitudes.
