Synapses psychology definition
WebApr 12, 2024 · Synaptogenesis is the process by which synapses are created , that is, connections between one neuron and another cell of the nervous system, or between two neurons. Although synaptogenesis is especially intense during early development, environmental influences influence the consolidation and disappearance of synapses … WebTopic: Memory. Learning occurs when stimuli in the environment produce changes in the nervous system. Three ways in which this occurs include long-term potentiation, habituation, and sensitization. One way that the nervous system changes is through potentiation, or the strengthening of the nerve synapses (the gaps between neurons).
