Abstract:
Many everyday actions require inhibitory control. The success of these actions depends on the availability of prior information regarding stopping demands. Using transcranial magnetic stimulation (TMS), Cirillo and colleagues (Cirillo J, Cowie MJ, MacDonald HJ, Byblow WD. J Neurophysiol 119: 877-886, 2018) provide novel neurophysiological evidence for distinct roles of intracortical inhibitory mechanisms underlying inhibitory control. Other, nonexclusive mechanisms such as disfacilitation of excitatory pathways and interhemispheric inhibition may also contribute to inhibitory control. Accordingly, diverse TMS protocols are a valuable assessment tool to investigate these mechanisms.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
