I’m currently interested in brain recognition (BR) strategies that maximize information processing utility, i.e., maximize recognition speed and accuracy while minimizing processing cost.  The brain minimizes perceptual computational load by continuously anticipating its future environment - freeing its resources for other jobs. Using a repetition priming procedure we have demonstrated how recognition is facilitated when it reoccurs in a recent context.  We simulate these processes with leabra neural network models. We have just begun a behavioral study to distinguish 2 BR components: 1. Time-decay in synaptic threshold modifications in the perceptual pathway, 2.  Context-based cortical-hippocampal top-down bias to that pathway. We are also modeling a BR trade-off: when to recognize a contextual cue that further degrades an already degraded target stimulus.
