Motor neurons generate pose-targeted movements via proprioceptive sculpting
Single motor neurons in Drosophila are stimulated to show that they direct head movements towards specific postures rather than generating fixed movement vectors, suggesting that the brain controls movements through a continuing proprioceptive–motor loop.

Synaptic wiring motifs in posterior parietal cortex support decision-making
Excitatory pyramidal neurons preferentially target inhibitory interneurons with the same selectivity and, in turn, inhibitory interneurons preferentially target pyramidal neurons with opposite selectivity, forming an opponent inhibition motif that supports decision-making.
