Visual feature selectivity in frontal eye fields induced by experience in mature macaques
Article Abstract:
Neurons in the frontal eye fields (FEF) of the cortex exhibit stimulus selectivity in macaques trained to respond to stimuli of a certain color. The selective behavior is seen rapidly on stimulus presentation and is unaffected by the position of the target in the visual field. This indicates that the FEF neurons are capable of an experience-dependent plasticity that regulates the learning of arbitrary stimulus-response relations. The initial visual response of the trained monkeys to the target is greater than that to distracters. The FEF neurons in untrained monkeys show no selectivity.

Race to explain procrastination
Article Abstract:
A mathematical model in which the random variation of saccade latencies is generated by random distribution of probabilities of the rate of growth of the accumulator signal is used for explaining the mechanisms of human behavioral patterns. Results obtained by the model show consistency with the experimental results. Importance of likelihood ratio in determining neuronal activity is discussed.

Performance monitoring by the supplementary eye field
Article Abstract:
Neurons in the supplementary eye field (SEF) of macaque monkeys were studied to assess the theory that SEF register the consequence of actions based on self-control.
