The ability of patients with Alzheimer's disease (AD) or global amnesia (AMN) to acquire skill for tracing a pattern seen in mirror-reversed view and to retain that skill over 24-h intervals was examined. Both patient groups had poor recall and recognition of their mirror-tracing experience, but they acquired and retained mirror-tracing skill as well as normal control subjects. One AMN patient (H.M.) retained the skill over a year-long interval. Furthermore, the patients transferred their skill…

Learning, Retention and Generalization of a Mirror Tracing Skill in Alzheimer's Disease

TLDR
The results indicate that acquisition and retention of a complex visuomotor skill can proceed normally in the early stages of AD in those individuals who can initially perform the basic task, and that inability to perform thebasic task may be related to the frontal lobe dysfunction that is often prominent in the disorder.

Intact mirror-tracing and impaired rotary-pursuit skill learning in patients with Huntington's disease: evidence for dissociable memory systems in skill learning.

TLDR
Results suggest that different forms of perceptual-motor skill learning are mediated by separable neural circuits, and that a striatal memory system may be essential for sequence or open-loop skill learning but not for skills that involve the closed-loop learning of novel visual-response mappings.

Sensorimotor skill learning in amnesia: additional evidence for the neural basis of nondeclarative memory.

TLDR
It is demonstrated unequivocally that sensorimotor skill learning does not require structures in mesial and lateral temporal regions nor in basal forebrain, and offers additional evidence that mesial temporal lobe damage spares skill learning.

Intact implicit memory for novel patterns in Alzheimer's disease.

TLDR
The finding of intact pattern priming in AD provides, for the first time, evidence that patternPriming depends on the peristriate cortex.

Procedural learning and retention relative to explicit learning and retention in mild cognitive impairment and Alzheimer's disease using a modification of the trail making test.

TLDR
Overall, this study confirms the dissociation between explicit relative to procedural learning and retention in aMCI and AD dementia and supports differing anatomical substrates.

Intact implicit habit learning in Alzheimer's disease.

TLDR
The authors tested patients with AD and controls on a probabilistic classification task in which participants implicitly acquire cue-outcome associations, and both groups showed evidence of learning across 50 trials, and performance did not differ significantly between the groups.

TLDR
Evidence is reviewed about which brain regions mediate specific kinds of procedural memory, including sensorimotor, perceptual, and cognitive skill learning; perceptual and conceptual repetition priming; and several forms of conditioning.

TLDR
The results support the existence of two, relatively independent, learning systems related to “declarative” and “procedural” knowledge and offer additional cognitive correlates for the selective damage to neural systems recently identified in AD.

Dissociations between skill learning and verbal recognition in amnesia and dementia.

TLDR
The results suggest that the memory disorder of patients with HD may appear much more severe when recall rather than recognition test paradigms are employed, due to an inability to generate strategies necessary to search their short- and long-term memories.

Normal McCollough effect in Alzheimer’s disease and global amnesia

TLDR
A dissociation between learning mechanisms that mediate recall and recognition versus mechanisms thatMediate the McCollough effect is demonstrated, consistent with other sources of evidence implicating early visual areas, especially V1, as a critical locus of the ME.

Impaired learning of a motor skill in patients with Huntington's disease.

TLDR
Results provide further evidence that the basal ganglia are critically involved in the acquisition of motor skills in patients with Huntington's disease, dementia, and amnesic patients.

Procedural memory in Parkinson's disease: impaired motor but not visuoperceptual learning.

TLDR
The results showed that PD patients were not impaired on mirror reading or paired associate learning, and the underlying processes/procedures for procedural learning are specific to the task, and are supported by different neuroanatomical systems.

Procedural learning and neostriatal dysfunction in man.

TLDR
Patients with early stage Parkinson's disease are shown to be selectively impaired in a cognitive task of procedural learning while remaining intact in recall and recognition tests of declarative memory, thus demonstrating a double dissociation.

The primate hippocampal formation: evidence for a time-limited role in memory storage.

TLDR
Results show that the hippocampal formation is required for memory storage for only a limited period of time after learning, and as time passes, its role in memory diminishes, and a more permanent memory gradually develops independently of the hippocampus.

ACQUISITION OF MOTOR SKILL AFTER BILATERAL MEDIAL TEMPORAL-LOBE EXCISION

The Neuropsychology of Memory

TLDR
This paper presents a summary of presently available information about the neuropsychology of human memory, emphasizing three ideas: a) the neural substrate of memory continues to change for a long time after initial learning, which is distinct from the changes underlying forgetting and involves the medial temporal region of the brain.
