Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.
Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.
In contrast to current models, inputs from midbrain limbic structures, but not from the hippocampus, are necessary for mammillary body contributions to memory.
Detailed analysis of fMRI data shows that sequences of movements are associated with individual patterns of neural activity that become more distinct with training.
Retrograde tracing of the neural circuits that control movement of the jaw and tongue reveals how shared premotor neurons help to ensure coordinated muscle activity.
Three-dimensional mapping of the neural circuitry that controls movement of a marine worm in response to light provides insights into the evolution of complex visual systems.
Midbrain dopaminergic neurons and a cortex-like structure called the arcopallium form part of a circuit that enables young songbirds to compare their own song with a template stored in memory, and use any discrepancies to improve their performance.
Neuroimaging provides novel insights into how the motor system represents sequences of actions by automatically separating their spatial and temporal features for flexible skill production.
