WebbThe life of cell consists of stages that make up the cell cycle. After a cell is born, it passes through an interphase before it is ready to replicate itself and produce daughter cells. This interphase includes two gap phases (G 1 and G 2 ), as well as an S phase, during which its DNA is replicated in preparation for cell division. Webb21 okt. 2011 · The concept of cell assembly was coined by the Canadian neuropsychologist D. O. Hebb (Hebb 1949) to describe a network of neurons that is being activated repeatedly during a certain mental process and in this way the excitatory synaptic connections among its members are being strengthened. In Hebb’s thinking the synaptic …

These cells were discovered by Torsten Wiesel and David Hubel in the late 1950s. Such cells are tuned to different frequencies and orientations, even with different phase relationships, possibly for extracting disparity (depth) informati…
