ARTICLE XXI. WHAT CONSTITUTES INSUFFICIENCY of the INTERNAL RECTI MUSCLES?

Coordination of the extraocular recti muscles in the cat.

With the use of multiple implanted electrodes in chronic preparations, the electromyograph of the spontaneous activity of the extraocular muscles has been studied in the unanesthetized and unrestrained cat. Simultaneous strain gauge records were also made for monitoring eye movement in acute, restrained preparations with the use of local anesthesia only. It was found that there was a constant o...

What Constitutes a Contract?

Sideways displacement and curved path of recti eye muscles.

We investigated the sideways displacement of recti muscles with the eye in various gaze-positions by making computed tomographic (CT) scans in a plane perpendicular to the muscle cone, posterior to the globe. We found no consistent sideways displacement of the horizontal recti in the up or down gaze or the vertical recti in the left or right gaze. We found a substantial displacement, however, o...

What Constitutes an Effective Representation?

This paper presents a taxonomy of 19 cognitive criteria for judging what constitutes effective representational systems, particularly for knowledge rich topics. Two classes of cognitive criteria are discussed. The first concerns access to concepts by reading and making inferences from external representations. The second class addresses the generation and manipulation of external representation...
