Memory consolidation in Hermissenda crassicornis
The Biological Bulletin, 2000Experiments with shell-less molluscs (Aplysia and Hermissenda) have revealed a number of processes that underlie learning by these organisms and also by some vertebrates. Hermissenda, for example, shows significant Pavlovian conditioning capabilities (1).

Memory Transformation and Systems Consolidation
Journal of the International Neuropsychological Society, 2011Abstract With time and experience, memories undergo a process of reorganization that involves different neuronal networks, known as systems consolidation. The traditional view, as articulated in standard consolidation theory (SCT), is that (episodic and semantic) memories initially depend on the hippocampus, but eventually become consolidated in ...

Histamine regulates memory consolidation
Neurobiology of Learning and Memory, 2017Recent findings have reasserted the role of histamine in the regulation of memory consolidation first proposed in 1986 in an inhibitory avoidance task in rats. They indicate that histamine is indeed a major regulator of memory consolidation in various tasks, through H2 receptors in the dorsal hippocampus and through H3 receptors in the basolateral ...

The Effects of Smoking on Memory Consolidation
The Journal of Psychology, 1983The effects of smoking deprivation and of smoking a single .8 mg, 1.3 mg or 2 mg nicotine yield cigarette, immediately post acquisition on a paired-associate learning task, were studied in 54 male smokers and 15 male nonsmokers. Subjects were retested for retention of the memorized material at intervals of one-half hour, one day, one week, and one ...

Systems consolidation and the content of memory
Neurobiology of Learning and Memory, 2013Systems consolidation is the process by which memories become independent of the hippocampus and stored in regions of the neocortex. This process is commonly studied in rodents using context fear conditioning. It is becoming increasingly clear, however, that context memories do not always undergo systems consolidation. To explain this fact, the current

Memory formation, consolidation and transformation
Neuroscience & Biobehavioral Reviews, 2012Memory formation is a highly dynamic process. In this review we discuss traditional views of memory and offer some ideas about the nature of memory formation and transformation. We argue that memory traces are transformed over time in a number of ways, but that understanding these transformations requires careful analysis of the various representations

Reconsolidation and the fate of consolidated memories
Neurotoxicity Research, 2008The predominant view about memory formation states that a consolidation process stabilizes newly acquired traces until they are safely stored in the brain. However, during the last ten years evidence has accumulated to indicate that, upon retrieval, consolidated memories are rendered again vulnerable to the action of metabolic blockers, notably protein

Neurobiology of systems memory consolidation
European Journal of Neuroscience, 2020Abstract Psychological theories posit that the hippocampus rapidly forms associations among ongoing events as they unfold. During a subsequent maturation process, so‐called systems memory consolidation, these associations are gradually stabilized within distributed neocortical circuits through close interactions between the ...

Hippocampal ripples and memory consolidation
Current Opinion in Neurobiology, 2011During slow wave sleep and quiet wakefulness, the hippocampus generates high frequency field oscillations (ripples) during which pyramidal neurons replay previous waking activity in a temporally compressed manner. As a result, reactivated firing patterns occur within shorter time windows propitious for synaptic plasticity within the hippocampal network

Memory consolidation in sleep disorders
Sleep Medicine Reviews, 2017In recent years sleep-related memory consolidation has become a central topic in the sleep research field. Several studies have shown that in healthy individuals sleep promotes memory consolidation. Notwithstanding this, the consequences of sleep disorders on offline memory consolidation remain poorly investigated.
