Neurons differ in their impact on collective cortical activity, with sensitive neurons forming a stable topological core, implicated in cortical-state transitions, while peripheral insensitive neurons are more responsive to stimuli.
Model-based analyses of human behaviour and neural activity show that representations of concurrent task-sets emerge by merging together representations of individual stimulus-response associations that occur in temporal proximity.
Distortion and elimination of limb visual feedback affects low-level stretch reflex control, indicating the involvement of a high-level and multimodal representation of the limb state in orchestrating hierarchical sensorimotor control.
Transcription factor Sox9 has an important role in neocortex expansion, where its expression in basal progenitors increases proliferation, induces premature gliogenesis and promotes the expression of extracellular matrix components.
The axonal cytoskeletal contains an actomyosin-II network that controls circumferential axonal contraction and expansion with the potential of regulating fluctuations in diameter during action potential firing, trafficking, and degeneration.
