Dendritic spines are small, protruding structures located on the dendrites of neurons that serve as the primary sites for synaptic connections and communication with other neurons. These spines play a crucial role in the formation and modulation of synapses, significantly influencing synaptic transmission and the overall processing of information within neural circuits. By increasing the surface area available for synaptic input, dendritic spines enhance the ability of neurons to integrate signals from multiple sources, impacting learning and memory processes.
congrats on reading the definition of Dendritic Spines. now let's actually learn it.
