Rall's Cable Model
This lecture covers Rall's cable model, focusing on the spread of synaptic potentials in dendrites. It explains the 1-D passive cable equation and its solutions for branched structures, emphasizing steep voltage attenuation. The lecture also discusses compartmental modeling and numerical simulations of Rall's cable equation, highlighting the local effect of excitatory synapses and the large attenuation to soma/axon region. It concludes by detailing the modeling of synaptic potentials, including the steep attenuation and shape changes as they propagate in dendrites, affecting spike initiation in the axon.
