This study uses TMS to show that superior occipital TMS impairs both egocentric and allocentric reaches, while inferior occipital TMS only affects allocentric performance, supporting a dorsal-ventral stream dissociation in memory-guided reaching.

The paper investigates how explicit instructions to use allocentric landmarks improve reach accuracy, precision, and reaction time compared to ignoring landmarks in a reach task.

The paper investigates how gaze, vision, and memory affect hand placement and orientation during a task involving 2D visual templates, showing feedback-dependent effects on location and orientation errors.

The paper compares single-unit and multi-unit activity in the frontal eye fields during a delayed saccade task, finding that multi-unit activity better captures visuomotor transformations while losing some cognitive signals.

This study shows that gaze-related activity in primate frontal cortex predicts and reduces spatial uncertainty during a cue-conflict task.

The paper investigates how landmark-centered and eye-centered visual signals are integrated in the supplementary eye fields (SEF) during saccadic eye movements in macaques.

The paper shows that prefrontal visual responses in macaques are influenced by external landmarks, with coding shifting toward landmark-centered when considering specific target-landmark configurations.

This study shows that frontal eye field neurons integrate eye-centered and landmark-centered visual codes during saccade tasks, with a transient shift toward allocentric coordinates before motor execution.

The paper shows that the superior colliculus rapidly transforms target to gaze coding during reactive saccades, with timing determining spatial coding across cell types.
