PSY397H5 Lecture Notes - Lecture 6: Long-Term Potentiation, Cerebrospinal Fluid, Dendritic Spine
Document Summary
Long term potentiation alters the connectivity between neurons. Depending on the synapse the connection may or may not pass the action potential to the next neuron. Pyramidal cells can tie connections between pyramidal cells and cortical neurons. The pyramidal cell is not just tied to visual cues, it is also tied to olfactory and other cues. They can send action potentials to numerous neurons in the presence of a stimulus. The connectivity between the pyramidal cells and the cortex allows ltp to occur. Ltp is the strengthening of neuronal connections and ltd is the weakening on neuronal cells shows the process of sending signals from the pyramidal cell to the cortex) The cellular and molecular basis of cognition. Memories are stored as alterations in the strength of synaptic connections between neurons in the cns. Co-activity of neurons will lead to connectivity of those neurons.
