General-purpose filter design for neural prosthetic devices

Brain-driven interfaces depend on estimation procedures to convert neural signals to inputs for prosthetic devices that can assist individuals with severe handicap scooters deficits. Previous estimation procedures were developed on an application-specific basis. Here we report a coherent estimation framework that unifies these procedures and motivates new applications of prosthetic devices driven by action potentials, local field potentials (LFPs), electrocorticography (ECoG), electroencephalography (EEG), electromyography (EMG), or optical methods. The brain-driven interface is described as a probabilistic relationship between neural activity and components of a prosthetic device that may take on discrete or continuous values. A new estimation procedure is developed for action potentials, and a corresponding procedure is described for field potentials and optical measurements. We test our framework against dominant approaches in an arm reaching task using simulated traces of ensemble spiking activity from primary motor cortex (MI) and a power wheelchairs navigation task using simulated traces of EEG-band power. Adaptive filtering is incorporated to demonstrate performance under neuron death and discovery. Finally, we characterize performance under model misspecification using physiologically realistic history dependence in MI spiking. These simulated results predict that the unified framework outperforms previous approaches under various conditions, in the control of position and velocity, based on trajectory and endpoint mean squared errors.

The effect of providing power mobility on body weight change

OBJECTIVE: To investigate whether the provision of power mobility would have an effect on body weight in adults who were first-time qualifiers for power mobility. DESIGN: This was a retrospective observational study of consecutive subjects, who served as their own controls. The medical scooters, www.easymedonline.com records of 468 subjects who were approved for power mobility during a 17-mo period were reviewed. Three weight groups (12 mos before, at, and 12 mos after the power mobility evaluation) were evaluated with repeated-measures analysis of variance (ANOVA). The weight changes on subjects in different age groups (45-54, 55-64, 65-74, and >74), in geriatric vs. nongeriatric groups, and in different body mass index (BMI) groups were analyzed. RESULTS: Eighty-nine subjects met the inclusion criteria. They were obese (49.4%), and most of them were geriatric (64%). Congestive heart failure (30.34%) and chronic obstructive pulmonary disease (22.47%) were the two main presenting diagnoses. The repeated-measures ANOVA showed no significant weight change in the three studied weight groups. Similar results were seen in the age and BMI subgroups. CONCLUSIONS: There was no statistically significant weight change in adults who were first-time qualifiers and who used power mobility for 1 yr.

Cichlid with the best characters

cichlid is one of the many tropical fish. There lots of species in cichlid tropical fish such as oscar cichlids, Red devils or midas cichlid and many more. I have somewhere around 100 types of fishes and the best cichlid tropical fish I’ve ever had in my opinion is midas cichlid. It is very intelligent which is very fascinating. Other than that I think Oscar cichlid is great too. I’ve heard that there are people who successfully teach their oscar cichlid to do some cool trick.
