Tuning dissimilarity explains short distance decline of spontaneous spike correlation in macaque V1.

Fast spike correlation is a signature of neural ensemble activity thought to underlie perception, cognition, and action. To relate spike correlation to tuning and other factors, we focused on spontaneous activity because it is the common 'baseline' across studies that test different stimuli, and because variations in correlation strength are much larger across cell pairs than across stimuli. Is the probability of spike correlation between two neurons a graded function of lateral cortical separation, independent of functional tuning (e.

Half-stained thread in shoulder arthroscopy: an improved method of suture management.

Shoulder arthroscopy is used widely to treat a variety of shoulder pathologies. These include various diagnostic and stabilization procedures such as Bankart repair, treating SLAP lesions, capsular plication, and rotator cuff repair. Sutures are commonly used, particularly in stabilization procedures, with or without the use of suture anchors.

Peroneal padding: an alternative to a peroneal post in hip arthroscopy.

Hip arthroscopy is commonly used both to diagnose and treat different underlying hip conditions. It may be performed either by a supine or lateral approach. A peroneal post is commonly used with a fracture table in both the supine and lateral positions to provide lateralization and traction of the femur.
