Novelty (Kaliukhovich & Vogels 2011, Li et al. 1993, Meyer & Rust 2018, Xiang & Brown 1998) | Predictive persistence | Retina and cortex | Evolution and/or development | Adaptation | Feedforward |
Reversal response (Chen et al. 2014, Schwartz et al. 2007) | Predictive change | Retina | Evolution and/or development | Adaptation | Feedforward |
Tethered Brownian motion (Palmer et al. 2015, Salisbury & Palmer 2016) | Predictive change | Retina | Evolution and/or development | Adaptation | Feedforward |
Flash lag effect (Anstis 2007, Eagleman & Sejnowski 2000, Hazelhoff & Wiersma 1924, Khoei et al. 2017, Lopez-Moliner & Linares 2006, Nieman et al. 2006, Nijhawan 2002, Patel et al. 2000, Sheth et al. 2000, Shioiri et al. 2010, Subramaniyan et al. 2018, Trenholm et al. 2013) | Predictive change | Retina and V1 | Evolution and/or development | Adaptation, gap-junction coupling | Feedforward |
Examples that are thought to involve feedback processing and more sophisticated forms of memory | |||||
Novelty with expectation (Grotheer & Kovacs 2014, Kovacs et al. 2013, Summerfield et al. 2008) | Predictive persistence | Human visual cortex | Learning in adulthood | Unknown | Feedback |
Configured image sequences (Hindy et al. 2016, Meyer & Olson 2011, Meyer et al. 2014, Schwiedrzik & Freiwald 2017) | Predictive change | High-level visual cortex (e.g., IT) | Learning in adulthood | Hippocampal pattern completion | Feedback |
The two classes of examples in this table cannot be parsed by the type of prediction or brain area, but they do align with the distinction between the times when the input correlations are learned (during evolution and development versus in adulthood, respectively). Abbreviation: IT, inferotemporal.
