Timing in the absence of clocks: encoding time in neural network states. (2007, background): “Indeed, much has been discovered about the mechanisms underlying the emergence of orientation-selective cells and their role in perception (e.g., Miller et al., 1989; Ferster and Miller, 2000; Gilbert et al., 2000; Schoups et al., 2001; Yang and Maunsell, 2004).”
Eligibility Traces and Plasticity on Behavioral Time Scales: Experimental Support of NeoHebbian Three-Factor Learning Rules (2018, background): “The authors hypothesized that these three-factor rules were related to rewardbased learning in cortex such as perceptual learning in monkeys (Schoups et al., 2001) or mice (Poort et al., 2015) or reward prediction (Shuler and Bear, 2006).”
Perceptual learning with spatial uncertainties. (2006, neutral): “ski, Schluppeck, & Engel, 2004; Ghose, Yang, & Maunsell, 2002; Schoups, Vogels, Qian, & Orban, 2001; Schwartz,”
Plasticity in the adult human auditory brainstem following short-term linguistic training (2008, result): “It is unlikely that passive exposure to the sounds would result in the same effect we observed ( Schoups, Vogels, Qian, & Orban, 2001 ), especially given that only the least familiar pitch contour showed pitch-tracking improvements.”
Deep Hierarchies in the Primate Visual Cortex: What Can We Learn for Computer Vision? (2013, background): “However, the measurable changes at the single-cell level induced by learning appear to be much smaller at earlier levels in the visual hierarchy such as V1 [154] compared to later stages such as V4 [139] or IT [104].”
In vivo two-photon imaging reveals a role of arc in enhancing orientation specificity in visual cortex. (2006, methodology): “In adults, daily practice of orientation identification tasks can further improve orientation selectivity (Schoups et al., 2001).”
Cortical layer–specific critical dynamics triggering perception (2019, result): “Consistent with an increase in size, tuning sharpness and/or reliability of the population representation (33, 34), this identical procedure resulted in slightly more neurons in each ensemble compared with the untrained cohort [39.”
Activation of Specific Interneurons Improves V1 Feature Selectivity and Visual Perception (2012, background): “Changes in V1 orientation tuningcan, in principle, affect perceptual discrimination 18,19 .”
If deep learning is the answer, what is the question? (2020, background): “…image is clockwise with respect to the reference. b | Tuning curve slope changes due to learning measured in primate primary visual cortex (V1) 150 . c | Tuning curve slope changes due to gradient descent learning in the model illustrated in part a 74 . d | Timing of peak synaptic changes in…”
Neural plasticity after peripheral nerve injury and regeneration. (2007, background): “, 1993), visual (Schoups et al., 2001; Schwartz et al., 2002) or involving skilled motor tasks (Nudo et al.”
