The study shows that the human brain uses the experience to different discriminate forms including auditory, visual and somatosensory. Neurons that respond to reward-driven stimulus are seen to be much stronger compared to those associated with omission of rewards. This means that there is enhanced response on neurons that carry reward relevant information. The process of perceptual learning has based the charges incurred on the sensory cortex as it is seen to have the signals used to make decisions (Spingath, Kang, and Plummer 1). This paper was based on the hypothesis that ‘neurons that prefer task targets will strengthen on detection learning, and will continue to strengthen on discrimination learning.’
Material and Methods
The model used for this research is trained Rhesus monkeys. It was aimed at identifying the effect of target stimuli that is followed by a reward and distracters stimuli that are supported by the omission of reward. These monkeys had custom cortical microarray impacted into them to allow the researchers to measure daily the learning process of the monkeys. The results collected from this experiment would be an essential contributor to the topic of reward association plasticity. It included the implantation of 64 electrodes in the somatosensory cortex of these monkeys. The responses were stabilized for six weeks before they were read. The reactions were read from the same skin surface throughout the expe…
