Active music therapy in the rehabilitation of severe brain injured patients during coma recovery.

Active improvised music therapy may offer an adjuvant from of treatment in the early rehabilitation of severe brain-injured patients. Active music therapy consists of musical improvisation between patient and therapist by singing or by playing different musical instruments, according to the vital functions, the neurological conditions and the motor abilities of the patients. We studied 34 severe brain-injured patients with a mean coma duration of 52 days +/- 37.

Algorithmic aspects of a neuron for coherent wave synapse realizations.

We study a neuron functional form (which we call the absolute value neuron) that arises naturally in analog devices in which the neuron synapses are realized using coherent oscillatory wave signals. We discuss algorithmic aspects of this neuron at both the single neuron and network level, including computational capabilities, generalization, and training. A numerical study of absolute value neural networks on two data sets is presented, which demonstrates performance competitive with standard neural networks.
