Dendritic Impedance in Neocortical L5 PT neurons (Kelley et al. 2021)
|
|
|
We simulated chirp current stimulation in the apical dendrites of 5 biophysically-detailed multi-compartment models of neocortical pyramidal tract neurons and found that a combination of HCN channels and TASK-like channels produced the best fit to experimental measurements of dendritic impedance. We then explored how HCN and TASK-like channels can shape the dendritic impedance as well as the voltage response to synaptic currents. |

Spreading Depolarization in Brain Slices (Kelley et al. 2022)
|
|
|
A tissue-scale model of spreading depolarization (SD) in brain slices.
We used the NEURON simulator's reaction-diffusion framework to implement embed thousands of neurons
(based on the the model from Wei et al. 2014)
in the extracellular space of a brain slice, which is itself embedded in an bath solution.
We initiate SD in the slice by elevating extracellular K+ in a spherical region at the center of the slice.
Effects of hypoxia and propionate on the slice were modeled by appropriate changes to the volume fraction
and tortuosity of the extracellular space and oxygen/chloride concentrations. |
