Improving Visual Perception through Neurofeedback

Improving visual perception through neurofeedback.

Perception depends on the interplay of ongoing spontaneous activity and stimulus-evoked activity in sensory cortices. This raises the possibility that training ongoing spontaneous activity alone might be sufficient for enhancing perceptual sensitivity. To test this, we trained human participants to control ongoing spontaneous activity in circumscribed regions of retinotopic visual cortex using ...

Visual perception: Learning to see through noise

New studies show that perceptual learning does not reduce the noise inherent to the neuronal mechanisms of perception. Rather, learning boosts the brain's capability to extract and make use of the relevant outside signal - but where and how the neuronal changes occur is still unknown.

Visual rhythm perception improves through auditory but not visual training

Figure 1. Experimental procedures and results of visual rhythm discrimination training. (A) Schematic of a visual trial from the rhythm discrimination task. In this example, the patterns of the rhythm sequences are different. (B) Depiction of the experimental design. Sessions were completed 24 to 48 hours apart. For all groups, the preand post-test trials contained visual stimuli only. (C) Mean...

Learning on the Job: Improving Robot Perception Through Experience

This paper is about robots that autonomously learn how to interpret their environment through use. Specifically, robot perception is improved with every outing through effortless human assistance. This is made possible by the fact that robots operate repeatedly in specific application domains. Our approach, which we call Experience-Based Classification (EBC), is similar in spirit to the concept...
