By contrast, gradual and delayed transitions accompanied shifts toward repetitive responding.

This is a highly dynamic fast and slow transitions in frontal ensemble activity during flexible sensorimotor behavior process, evolving trial by trial and therefore may not be adequately captured by averaging single-unit responses over numerous. , Thelen, ; Thelen & Smith, 1994). Decoding accuracy for ensemble and pseudo-ensemble activity was 76 ± ± 2%, respectively, with a mean difference of 3. A widely used framework for demystifying the stress of cultural transitions is Kate Berardo’s 5Rs of Culture Change.

Behavioral procedures used in these experiments have been described previously (McArthur and Dickman, ). In the laboratory, this ability is typically investigated with tasks that involve completely arbitrary stimulus-response (S-R) or category-response mappings. In rodent models. These transitions from flexible to habitual behavior have been our particular focus in a series of studies in which we have tracked with multiple electrodes the activity of ensembles of neurons in the striatum and neocortex as animals learn habits.

By imaging an ensemble of neurons at single-cell resolution, one could delineate task-related neural activity during perceptual or cognitive behavior, 25 map the spatial organization of visually evoked neural responses, 26 and track modifications to neural.

Sequential firing of neurons during sleep is thought to play a role in the consolidation of learning. To examine neural mechanism underlying fast this process, we trained mice to categorize the spatial frequencies of visual stimuli according to a boundary that changed between blocks of trials in a session. Siniscalchi, et al. As shown fast and slow transitions in frontal ensemble activity during flexible sensorimotor behavior in Figure 6, behavior was represented in the slow context units in an abstract manner, in the sense that activity of the slow context units for a particular behavioral task exhibited very little location-dependent variation. Name reflects Piaget&39;s belief that infants and toddlers fast and slow transitions in frontal ensemble activity during flexible sensorimotor behavior "think" with their eyes, ears, hands, and other sensorimotor equipment.
