Neural populations from various sensory regions demonstrate dynamic range adaptation in response to changes in the statistical distribution of their input stimuli. These adaptations help optimize the transmission of information about sensory inputs. Here, we show a similar effect in the firing rates of primary motor cortical cells. We trained monkeys to(More)
While much of diagnostic radiology is practiced in a private setting, many of the papers and presentations describing picture archiving and communications systems (PACS) implementation to date have been sponsored by university and government health facilities. We will present a 4-year retrospective review of a private practice PACS project. The challenges,(More)
In brain-machine interface (BMI) prosthetic systems, recordings of brain activity are used to control external devices such as computers or robots. BMI systems that have shown the highest fidelity of control use neural signals recorded directly from microelectrodes in the brain to control upper-limb prostheses. These have progressed from allowing control of(More)
Neurons from various sensory regions have been shown to demonstrate gain control or dynamic range adaptation in response to changes in the statistical distribution of their input stimuli. Although a similar phenomenon has been observed in single neurons in primary motor cortex (M1) during an isometric force task (Hepp-Raymond, et. al. Exp Brain Res 1999(More)
