Corticospinal vs Rubrospinal Revisited: An Evolutionary Perspective for Sensorimotor Integration.
Rafael Olivares-Moreno,Paola Rodriguez-Moreno,Veronica Lopez-Virgen,Martín Macías,Moisés Altamira-Camacho,Gerardo Rojas-Piloni +5 more
TL;DR: In this article, anatomical, neurophysiological, and behavioral evidence suggest that both systems modulate complex segmental neuronal networks in a parallel way, which is important for sensorimotor integration at spinal cord level.
Corticospinal neurons from motor and somatosensory cortices exhibit different temporal activity dynamics during motor learning
TL;DR: In this paper , the authors examined the functional roles of CSp neurons in both areas and found that S1 and M1 CSP neurons display a different temporal dynamic during movements that occurred when animals learned the task, reinforcing the idea of the diversity of the CSp system.
1 MOTOR CORTEX PROJECTIONS TO RED NUCLEUS AND PONS HAVE DISTINCT 1 FUNCTIONAL ROLES IN THE MOUSE 2 Abbreviated title : Corticopontine vs corticorubral projections 3
Veronica Lopez-Virgen,Martín Macías,Paola Rodriguez-Moreno,Rafael Olivares-Moreno,Victor de Lafuente,Luis Concha,Gerardo Rojas-Piloni +6 more
TL;DR: Corticopontine neurons projecting to the red and pontine nuclei constitute distinct functional and anatomical pathways and they contribute differently to sensorimotor integration, suggesting that layer 5 output neurons are functionally compartmentalized generating, in parallel, different downstream coding.
Motor cortex projections to red and pontine nuclei have distinct roles during movement in the mouse
Veronica Lopez-Virgen,Martín Macías,Paola Rodriguez-Moreno,Rafael Olivares-Moreno,Victor de Lafuente,Gerardo Rojas-Piloni +5 more
TL;DR: In this paper , the authors analyzed mouse motor cortex L5 pyramidal neurons projecting to the red and pontine nuclei during movement preparation and execution and revealed that both types of neurons activate with different temporal dynamics.
Phosphorylation of Tau protein correlates with changes in hippocampal theta oscillations and reduces hippocampal excitability in Alzheimer's model.

TL;DR: Mechanistically, it is shown that pyramidal neurons and some parvalbumin-positive interneurons in 1-month-old triple-transgenic AD mice accumulate hyperphosphorylated Tau protein and that this accumulation correlates with changes in theta oscillations in hippocampal neurons, suggesting neuronal responses that compensate for brain circuit overexcitation.
