Cardiac memory and cortical memory.
To the Editor: Dr Rosen and colleagues1 elegantly reviewed similarities between cortical and cardiac memory and presented new perspectives on the evolution of cardiac arrhythmias. We propose that, in addition to ion channels and gap junctions, myocyte size can also change in response to altered activation sequence and behaves like a “memory element.” In developing cortical memory, neurons form ...
متن کاملCortical dynamics of memory.
Memory networks are formed in the cerebral cortex by associative processes, following Hebbian principles of synaptic modulation. Sensory and motor memory networks are made of elementary representations in cell assemblies of primary sensory and motor cortex (phyletic memory). Higher-order individual memories, e.g. episodic, semantic, conceptual - are represented in hierarchically organized neuro...
متن کاملContrasting cortical activity associated with category memory and recognition memory.
We collected functional neuroimaging data while volunteers performed similar categorization and recognition memory tasks. In the categorization task, volunteers first studied a series of 40 dot patterns that were distortions of a nonstudied prototype dot pattern. After a delay, while fMRI data were collected, they categorized 72 novel dot patterns according to whether or not they belonged to th...
متن کامل[Hippocampal-prefrontal cortical circuit and working memory].
The study on learning and memory is one of the striking subjects in neuroscience today. In the cerebral cortex, it is has been proved that, the hippocampus, the prefrontal cortex and the hippocampal-prefrontal cortical circuit are important to working memory. In this paper, we review findings of the anatomical and electrophysiological characteristics of the hippocampal-prefrontal cortical circu...
متن کاملAmygdala Strengthening of Cortical Memory Representations
Emotionally arousing experiences generally create strong, long-lasting memories [3]. Findings of many experiments using rats, as well as human subjects, indicate that arousalinduced release of adrenal hormones epinephrine and cortisol (corticosterone in rats) plays a critical role in modulating the consolidation of memories [4-6]. Systemic administration of epinephrine or corticosterone to rats...
