WebApr 13, 2024 · Our model predicts that the refractory period of neurons, which has often been neglected, is essential for these behaviors. 1 Introduction A major interest in neuroscience is understanding how macroscopic brain functions, such as cognition and memory, are encoded at the microscale of neurons and their topological connectivities. WebApr 11, 2024 · Models of the human auditory nerve suggest that both anodic and cathodic electrical pulses can stimulate peripheral processes of healthy auditory neurons at relatively low levels, whereas anodic pulses more effectively stimulate the central axon, particularly at high levels or when peripheral processes are degenerated (Rattay, 1999; Rattay et …
