웹In contrast to the primary dendrite, mitral/tufted cell secondary (or basal) dendrites radiate up to 1000 μm horizontally, spanning almost the entire olfactory bulb.In the EPL, mitral/tufted cell dendrites interact with the dendrites of granule cells and both contain synaptic vesicles (Figure 1.4; Price and Powell, 1970).As granule cells are the largest group of bulbar interneurons … • Pyramidal neuron visualized by green fluorescent protein (gfp) • A hippocampal pyramidal cell One of the main structural features of the pyramidal neuron is the conic shaped soma, or cell body, after which the neuron is named. Other key structural features of the pyramidal cell are a single axon, a large apical dendrite, multiple basal dendrites, and the presence of dendritic spines.

웹2014년 9월 4일 · Thome et al. find that axons of hippocampal pyramidal cells frequently derive from a basal dendrite rather than from the soma. These dendrites constitute a privileged channel for excitatory synaptic input, generating a major functional asymmetry in a subset of cortical neurons. A basal dendrite is a dendrite that emerges from the base of a pyramidal cell that receives information from nearby neurons and passes it to the soma, or cell body. Due to their direct attachment to the cell body itself, basal dendrites are able to deliver strong depolarizing currents and therefore have a strong … 더 보기 Basal dendrites are part of sampling dendritic arbors. These arbors are classified as sampling because they are not completely space filling, but make more than one specific, or selective connection.
