[ 1 ] In neuroscience , long-term potentiation ( LTP ) is a persistent strengthening of synapses based on recent patterns of activity.
In neurophysiology, long-term depression (LTD) is an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer following a long patterned stimulus. LTD occurs in many areas of the CNS with varying mechanisms depending upon brain region and developmental progress.
In these cases of planned obsolescence, there is an information asymmetry between the producer, who knows how long the product was designed to last, and the customer, who does not. When a market becomes more competitive, product lifespans tend to increase.
