Proteolytic activity, synapse elimination, and the Hebb synapse
Journal of Neurobiology, 1994AbstractThe Hebb synapse has been postulated to serve as a mechanism subserving both regulation of synaptic strength in the adult nervous system (long‐term potentiation and depression) and developmental activity‐dependent plasticity. According to this model, pre‐ and postsynaptic temporal concordance of activity results in strengthening of connections,

Thalamocortical synapses inform the cerebral neocortex about the external and internal worlds. The thalamus produces myriad thalamocortical pathways that vary in morphological, physiological, pharmacological and functional properties. All these features are of great importance for understanding how information is acquired, integrated, processed, stored

MicroRNAs (miRNAs) are emerging as key modulators of post-transcriptional gene regulation in a plethora of tissues, including the nervous system. Recent evidence points to a widespread role for neural miRNAs at various stages of synaptic development, including dendritogenesis, synapse formation and synapse maturation.

It has long been held that the rise of neurons as a specialized cell type also marked the onset of the grand evolutionary journey for chemical synapses. Research over recent decades has shown, however, that the most dynamic chapters of synaptic history have been 'written' out of the context of neurobiology and neuronal evolution, dating back to the ...

Synapse selection based on differences in synapse turnover
International Journal of Developmental Neuroscience, 1983AbstractRat retinal neurons formed transient synapses with rat muscle cells in culture only during a discrete period in development, from the 20th day of embryonic development to the 7th neonatal day. In contrast, chick embryo spinal cord neurons formed synapses at all developmental stages tested, from the 2nd to the 18th day of embryonic development ...

Synapse elimination, the size principle, and Hebbian synapses
Journal of Neurobiology, 1995AbstractSynapse elimination at the vertebrate neuromuscular junction reduces a polyinnervated population of muscle fibers to a monoinnervated state. The function of this developmental phenomenon (if any) is unproven. A theoretical analysis of Hebbian (correlation) rules connecting presynaptic and postsynaptic activity and synaptic strength at the ...
