L-DOPA Rescues Reach Height but Not Trajectory Area in a Bimanual String-Pulling Behavior in Parkinsonian Rats

This study shows that L-DOPA improves certain motor features but not others in a bimanual string-pulling task in Parkinsonian rats.

Hippocampus-evoked polysynaptic responses in the medial prefrontal cortex are attenuated in aged rats.

This study shows that aging in rats reduces polysynaptic responses in the medial prefrontal cortex but preserves direct synaptic transmission from the hippocampus.

Modeling the journey as well as the destination: a control theory account of rotational navigation

This paper develops a closed-loop model of rotational navigation that explains how heading estimates are transformed into motor commands, showing that prediction errors drive corrective movements.

Illusory path configurations reveal age-related differences in egocentric pointing variability

This study finds that older adults show different egocentric pointing variability in virtual reality tasks involving illusory path configurations compared to young adults.

Opposing responses of hippocampal theta oscillations to running and a forelimb-dominated sensorimotor behavior

This paper investigates how hippocampal theta oscillations respond to different motor behaviors, finding distinct relationships between theta frequency, movement speed, and paw actions during string pulling versus running.
