|Abstract: ||Neurofeedback (NF) is an electroencephalographic (EEG) biofeedback technique for
training individuals to alter their brain activity via operant conditioning. Research has
shown that NF helps reduce symptoms of several neurological and psychiatric disorders,
with ongoing research currently investigating applications to other disorders and to the
enhancement of non-disordered cognition. The present article briefly reviews the fundamentals
and current status of NF therapy and research and illustrates the basic approach with
an interim report on a pilot study aimed at developing a new NF protocol for improving cognitive
function in the elderly. EEG peak alpha frequency (PAF) has been shown to correlate
positively with cognitive performance and to correlate negatively with age after childhood.
The present pilot study used a double-blind controlled design to investigate whether training
older individuals to increase PAF would result in improved cognitive performance. The
results suggested that PAF NF improved cognitive processing speed and executive function,
but that it had no clear effect on memory. In sum, the results suggest that the PAF NF
protocol is a promising technique for improving selected cognitive functions.|
