Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
Declarative memory has also been shown to benefit from sleep, but not in the same way as procedural memory. Declarative memories benefit from the slow-waves nREM sleep. [ 7 ] A study [ 12 ] was conducted where the subjects learned word pairs, and the results showed that sleep not only prevents the decay of memory, but also actively fixates ...
If PKA or protein synthesis inhibition occurs at certain moments during sleep, memory consolidation can be disrupted [citation needed]. In addition, mice with genetic inhibition of PKA have been shown to have long-term memory deficits. [48] Thus, sleep deprivation may act through the inhibition of these protein synthesis pathways.
Children become able to replicate more complex events with greater detail, from memory. [9] Jean Piaget, a child development psychologist, conducted a study testing the cognitive and memory abilities of children around 2 years of age. These tests were conducted using objects presented to the child followed by their removal from sight.
Based on targeted memory reactivation (TMR) experiments that use associated memory cues to triggering memory traces during sleep, several studies have been reassuring the importance of nocturnal reactivations for the formation of persistent memories in neocortical networks, as well as highlighting the possibility of increasing people's memory ...
The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is ...
You may have heard of white noise used to mask background sounds. The science is new with only a few small studies behind it, but that hasn’t stopped thousands of people from listening to hours ...
Procedural memory is a type of implicit memory (unconscious, long-term memory) which aids the performance of particular types of tasks without conscious awareness of these previous experiences. Procedural memory guides the processes we perform, and most frequently resides below the level of conscious awareness.
