The Neurobiology of Memory and Aging

Neurobiology of memory and aging "I also lost my key again." I shouted when my mother was eating a few days ago. "I am really old." Many elderly people are associated with amnesia and other neurobiological functions. Aging seems to occur simultaneously with losing and forgetting things. Is there a neurobiological explanation for this phenomenon? Neurobiologists are well aware that aging results in a reduction in brain size and a decrease in brain function.

Our understanding of neurobiological mechanisms of memory formation, integration, and retrieval can explain at least to some extent that certain memory distortions occur and why "imperfect" memory is normal . At the cellular and molecular level, these mechanisms are thought to be involved in processes associated with long-term potentiation (LTP) and long-term depression (LTD). Hebb 44 proposes a conceptual framework that combines the formation of associative memory with changes dependent on the activity of connection strength in the network, but Bliss and Lømo provide the first direct evidence for this connection ing. They found that entorhinal cortical neurons increase the ease of stimulating dentate gyrus neurons by strongly stimulating the perforation pathway from the entorhinal cortex to the dentate gyrus. The enhancement of this connection remains fairly stable and is known as LTP. LTP is activity-dependent and requires simultaneous stimulation of neuron pairs

Attention, learning, and memory (1728) includes studies of neurobiological and psychological processes, and mechanisms that affect attention, learning, and memory. Research processes through content areas include familiarization, sensitization, associative learning, manipulating learning, observational learning, and other processes that organisms participate to learn about the environment. The content area includes research on various types of short-term / work and long-term memory (eg declarative, procedural, autobiographical, spatial). In addition to basic research on learning and memory development processes, this content area also includes attention, learning and memory disorders, especially Alzheimer's disease and related dementia, and interventions (eg recognition) to address these cognitive disorders Yes.
