• Re-evaluating circuit mechanisms underlying pattern separation (2019, positive): “The evolutionarily conserved, highly regular structure of the cerebellar cortex has encouraged much speculation as to how the computations required for these functions are achieved (Figure 2A; Braitenberg, 1961; Eccles et al., 1967; Marr, 1969; Albus, 1971; Fujita, 1982; Pellionisz and Llinas, 1982;”
• Shunting inhibition modulates neuronal gain during synaptic excitation. (2003, unknown): “separation in the cerebellar cortex (Marr, 1969; Tyrrell and Willshaw, 1992).”
• Properties of Somatosensory Synaptic Integration in Cerebellar Granule Cells In Vivo (2006, background): “…sparse coding in granule cells have heavily influenced current models about the function of the cerebellar granule layer (Marr, 1969; Albus, 1971; Tyrrell and Willshaw, 1992; Houk et al., 1996; Schweighofer et al., 1998, 2001; Wolpert et al., 1998; Chadderton et al., 2004; Semyanov et al., 2004).”
• Tonically active GABA A receptors: modulating gain and maintaining the tone. (2004, background): “Because sparse coding is thought to be important in pattern separation [ 53 ,54], tonic inhibition-mediated reductions in granule cell gain are likely to enhance the number of motor control programs that could be stored in the cerebellar cortex.”
• Purkinje cells directly inhibit granule cells in specialized regions of the cerebellar cortex (2016, unknown): “Classical Marr-Albus theories and computational models of the cerebellum indicate that sparse coding in the input layer expands the number of patterns that can be stored at the output layer (Albus, 1971; Marr, 1969; Tyrrell and Willshaw, 1992).”
• Optimal degrees of synaptic connectivity (2017, unknown): “…granule cells presynaptic to a single Purkinje cell in the rat are estimated to be N = 7,000 and M = 209,000 (Marr, 1969; Harvey and Napper, 1991; Tyrrell and Willshaw, 1992; see STAR Methods), meaning the expansion ratio in this case is 30 if the mossy fibers are assumed to be independent…”
• Network Structure within the Cerebellar Input Layer Enables Lossless Sparse Encoding (2014, background): “…enabling downstream cerebellar circuits to perform more effective associative learning (Albus, 1971; D’Angelo and De Zeeuw, 2009; Marr, 1969; Medina and Mauk, 2000; Schweighofer et al., 2001; Tyrrell and Willshaw, 1992), adaptive filtering (Fujita, 1982), and binary addressing (Kanerva, 1988).”
