Multiscale computer model of the spinal dorsal horn reveals changes in network processing associated with chronic pain

L Medlock, K Sekiguchi, S Hong… - Journal of …, 2022 - Soc Neuroscience
Pain-related sensory input is processed in the spinal dorsal horn (SDH) before being
relayed to the brain. That processing profoundly influences whether stimuli are correctly or …

Pareto optimality, economy–effectiveness trade-offs and ion channel degeneracy: improving population modelling for single neurons

P Jedlicka, AD Bird, H Cuntz - Open biology, 2022 - royalsocietypublishing.org
Neurons encounter unavoidable evolutionary trade-offs between multiple tasks. They must
