Naturally occurring fluctuation in dendriticspine density on adult hippocampal pyramidal neurons. Dendriticspine changes associated with hippocampal long-term synaptic plasticity. In addition to a reduction in neuropil volume, there is evidence for reduced dendriticspine density in some cortical regions. Note the transient interaction between an astrocytic process (arrowhead) and a retracting dendriticspine (asterix). Each dendriticspine also received an alpha synapse on its end. Broadly speaking, two measures of prefrontal synaptic connectivity, neuropil volume and dendriticspine density, are reduced. Reduced dendriticspine density on cerebral cortical pyramidal neurons in schizophrenia. Glia are even more structurally dynamic, but the physiological implications have received far less attention than dendriticspine length changes, for example. Dendrites disintegrate and reassemble rapidly during ischemiaas with stroke, survivors showed an increase in dendriticspine turnover.

It also stimulates dendrite and dendriticspine development and regulates the continuing migration of neuroblasts generated in adult neurogenesis sites like subventricular and subgranular zones.

Dendrites are beaded and bear a few dendritic spines, as well as a small number of complex dendritic appendages. Dendritic spines: role of active membrane in modulating synaptic efficacy. The ganglion cell's dendrites densely branch over the region of arborization, and many dendritic spines are present. In these same time periods catecholamines induce dynamic changes in the shape and branching patterns of dendrites and the growth of dendritic spines. Dendritic spines constitute the post-synaptic compartment of most excitatory synapses in mammalian brain. It appears to occur primarily in the pool of synapses that are located on dendritic spines. These results demonstrate that astrocytes can rapidly remodel in the neuropil, presumably concurrent with dynamic changes in dendritic spines. This included the frequency of branching, whether the daughter branches were mainly symmetrical 0asymmetrical, and the presence 0 absence of dendritic spines. Furthermore, synaptic hyperpolarization and depolarization remains somewhat isolated due to the resistance from the narrow dendriticspine stalk, allowing a polarization to spread without much interruption to the other spines.
