Parkinson's Disease, as you note, is believed to occur due to damage or degeneration to the basal ganglia, especially the substantia nigra. Cells in the basal ganglia and substantia nigra produce dopamine, and in fact, the majority of the brain's dopaminergic cells have their bodies here, but that isn't the whole story. From Kandel's Principles of Neural ...

I don't give a. Essentially thats what your brain is saying after response suppression has taken hold. In general there is a registration of the stimulus during habitation but the consequence of the stimulus has been recorded as low priority through sensory integration. You can live in some terrible climates we acclimate to physical and psychological ...

The two concepts are analogous and mutually illustrative, but empirically refer to different levels of analysis: behavioral and neural. Habituation Habituation is a form of non-associative learning, specifically, learning that a stimulus is behaviorally unimportant. If I loudly and repeatedly bang on a metal pot immediately behind your head, you will ...

I look through 1) broad review journals, 2) broad empirical journals and 3) more specific empirical journals. In general, I find that popular media outlets do a poor job of reporting on research in psychology/neuroscience (but hopefully someone ...

From this perspective, the differences that you describe (left vs. right more complicated than up vs down) stem from the properties of how we perceive the world in our bodies: ...

This may be a similar thing in that people tend to think about mortality as they get older. Also, trying to tie down a whole host of beliefs like ...

I wouldn't say that it is around 30 but rather around 40 that people (especially women) become more spiritual. These are the reasons that I can discern: When parents are 40 or older, the children finally grow up and leave their home. Parents have to reorientate themselves and redefine their family, relationships, and goals. Some become grandparents. Women ...

Short answer Yes, there is a difference between hearing and understanding sound. Background Acoustic information is processed in different neural centers along the auditory pathway. The auditory system runs from the peripheral end organ in the inner ear (the cochlea) to the cortex. Along the way various processing steps are carried out. For ...
