Structural correlates of prospective memory.
Prospective memory (PM) includes the encoding and maintenance of an intention, and the retrieval and execution of this intention at the proper moment in the future. The present study expands upon previous behavioral, electrophysiological, and functional work by examining the association between grey matter volume and PM. Estimates of grey matter volume in theoretically relevant regions of inter...
متن کاملNeural correlates of prospective and retrospective memory.
This study examines the event-related brain potential (ERP) correlates of retrieval processes in prospective and retrospective memory (i.e., recognition and cued-recall). In contrast to previous research that has compared performance on tasks measuring prospective and retrospective memory, the stimulus materials and encoding and response demands of the prospective and retrospective components o...
متن کاملFunctional correlates of prospective memory in stroke.
INTRODUCTION Prospective memory is the ability to remember actions to be performed later in time or when a certain event occurs. Multiple cognitive processes are involved in prospective memory, and the degree to which automatic or effortful processes are involved may differ for different types of prospective memory tasks. This study aimed to investigate prospective memory (dys)functioning in st...
متن کاملStructural Synaptic Correlates of Learning and Memory
The majority of excitatory synapses in the brain are found on small dendritic protrusions called spines. Although the primary postsynaptic component of a synapse, the postsynaptic density (PSD), can only be resolved at the electron microscopic level, recent studies at the light microscopic level have shown that dendritic spines are extremely dynamic, capable of changing their shape and disappea...
متن کاملNeural correlates of prospective memory impairments in schizophrenia.
OBJECTIVE Prospective memory (PM) refers to the ability to remember to carry out intended actions after a delay. PM impairments are common in schizophrenia patients and are thought to be related to their prefrontal cortex dysfunction; however, this has not yet been examined directly in the research literature. The current study aimed to examine abnormalities in brain activation during PM task p...
