Neural activation down to the spinal cord during action language? A transcranial magnetic stimulation and peripheral nerve stimulation study.

This study investigates whether action language modulates spinal motor pathways, finding no effect on high-threshold motoneurons during action reading, unlike motor imagery.

Exploring dynamic brain oscillations in motor imagery and low-frequency sound

This study examines brain activity during motor imagery and low-frequency sound listening, finding variability in alpha and beta power responses but no additional modulation from combining the two tasks.

Explicit and implicit motor simulations are impaired in individuals with aphantasia

The paper investigates motor simulation deficits in aphantasia by comparing MEP responses during motor imagery and action observation between phantasics and aphantasics.

Mental simulations and action language are impaired in individuals with aphantasia

The paper investigates motor simulation during action reading in individuals with and without aphantasia, finding reduced corticospinal excitability and comprehension in aphantasics.

Imagining and reading actions: towards similar motor representations

The paper investigates whether action language and motor imagery share motor representations through behavioral and neurophysiological experiments.

Does the motor cortex want the full story? The influence of sentence context on corticospinal excitability in action language processing

The paper investigates how sentence context affects corticospinal excitability during action verb processing, finding that rich context sharpens motor representations.

Reading negative action verbs: one or two-step processing within the primary motor cortex?

The paper investigates motor cortex activation during reading of affirmative and negative action sentences, finding similar corticospinal excitability for both but increased inhibition at later latencies, supporting a two-step model of negation.

Mental practice modulates functional connectivity between the cerebellum and the primary motor cortex.

This study shows that mental practice improves motor skill accuracy and speed and alters functional connectivity between the cerebellum and primary motor cortex.
