Experiments using two different methods and three types of stimuli tested whether stimuli at nonadjacent locations could be selected simultaneously. In one set of experiments, subjects attended to red digits presented in multiple frames with green digits. Accuracy was no better when red digits appeared successively than when pairs of red digits occurred simultaneously, implying allocation of at...

OBJECTIVES This study aims to retrospectively evaluate results of arthroscopic dorsal ligamento capsulodesis in Geissler grade 2 and 3 scapholunate ligament injuries. PATIENTS AND METHODS Thirty-two patients (20 males, 12 females; mean age 30.1 years; range 21 to 42 years) who were performed arthroscopic dorsal ligamento capsulodesis due to Geissler grade 2 and 3 scapholunate ligament injurie...

The recognition of handwritten digits is an application which has been used as a benchmark for comparing shape recognition methods. We train COSFIRE filters to be selective for different parts of handwritten digits. In analogy with the neurophysiological concept of population coding we use the responses of multiple COSFIRE filters as a shape descriptor of a handwritten digit. We demonstrate the...

In this study, we focused on how subjects with Parkinson's disease (PD) grasp and lift with five-digits of the hand. This task provided the opportunity to simultaneously examine (a) the coordination of multiple segments (i.e., digits), (b) the sequencing of multiple tasks (i.e., force development, object lift, and hold), and (c) the control of force output. We found that PD patients coordinated...

The detailed structure of multidigit receptive fields (RFs) in somatosensory cortical areas such as the SII region has not been investigated previously using systematically controlled stimuli. Recently (Fitzgerald et al., 2004), we showed that the SII region comprises three adjoining fields: posterior, central, and anterior. Here we characterize the RF structures of the 928 neurons that were re...

The current study investigated inter-digit co-ordination and object-digit interaction during sustained object holding tasks by using five, six-component force/torque sensors. The sum of the individual finger normal forces and the thumb normal force showed a parallel variation with a mean median correlation coefficient of 0.941. The normal force traces demonstrated the lowest coefficient of vari...

In the present paper we provide a formula that allows to compute number of stable digits any integer tetration base \in {\mathbb N}_0. The digits, at given height power tower, indicates how many last (generic) are frozen. Our is exact for every which not coprime 10, although maximum gap equal V(a)+1 (where V(a) denotes constant congruence speed a) can occur, in worst-case scenario, between uppe...
