Control of eye-head coordination during orienting gaze shifts

Article Abstract:

The combined action of oculomotor, vestibular and neck motor systems is involved in gaze control. Several experiments have shown that the superior colliculus contains a species-specific motor map which determines eye and head movements according to oculomotor range. The large oculomotor range in monkeys elicit eye movements, eye-head movements for small oculomotor range in cats and head movements for absence of ocular motility in owls. Humans use saccadic movements to displace gaze shifts.

Semantic interference during blocked-cyclic naming: Evidence from aphasia

Article Abstract:

Semantic blocking effect is replicated in older controls and it is shown that in aphasia, the effect is manifested in increased error rates when naming semantically homogeneous, compared to mixed blocks. It is demonstrated that semantic blocking affects Broca's aphasics more than a matched group of NonBrocas, and that the effect increases with repetition of the blocked sets.
