It is typically assumed that the conscious experience of wanting to move is not the driving force for motor planning, but the secondary consequence of the unconscious neural processes preparing the movement. A recent study by Schneider et al. [Schneider, L., Houdayer, E., Bai, O., & Hallett, M. What we think before a voluntary movement. Journal of Cognitive Neuroscience, 25, 822–829, 2013] seems consistent with this dominant view by showing that the brain can be preparing to make voluntary movements not only “prior to the conscious appreciation that this is happening” but also “while subjects are thinking about something else.” However, an alternative hypothesis exists. It is supported by several lines of evidence and suggests that the early neural signals recorded by Schneider et al. (and others) do not reflect movement preparation per se, but rather a buildup in neural activity that ultimately leads to the emergence of a conscious intention to move. According to this view, the conscious experience of wanting to move is not the consequence but the cause of movement initiation.

A central aim in cognitive neuroscience is to explain how neural activity gives rise to perception and behavior; the causal link of paramount interest is thus from brain to behavior. Functional neuroimaging studies, however, tend to provide information in the opposite direction by informing us how manipulation of behavior may affect neural activity. Although this may provide valuable insights into neuronal properties, one cannot use such evidence to make inferences about the behavioral significance of the observed activations; if A causes B, it does not necessarily follow that B causes A. In contrast, brain stimulation techniques enable us to directly modulate brain activity as the source of behavior and thus establish causal links.

Neuroimaging results have raised interest in characterizing hemispheric asymmetries in prefrontal activity during different types of memory retrieval tasks. In this issue, Dobbins et al. and Mitchell et al. report results suggesting that the two hemispheres of the prefrontal cortex may indeed make different contributions to memory retrieval. Here, I discuss these findings within the context of studies characterizing more general processing differences between the cerebral hemispheres and studies characterizing prefrontal organization along the dorsal– ventral and anterior–posterior dimensions.
