Loss of Motor Cortical Inputs to the Red Nucleus after CNS Disorders in Nonhuman Primates

Simon Borgognon

The premotor (PM) and primary motor (M1) cortical areas broadcast voluntary motor commands through multiple neuronal pathways, including the corticorubral projection that reaches the red nucleus (RN). However, the respective contribution of M1 and PM to co ...

Tau seeds from patients induce progressive supranuclear palsy pathology and symptoms in primates

Tomislav Milekovic, Grégoire Courtine, Flavio Raschella

Progressive supranuclear palsy is a primary tauopathy affecting both neurons and glia and is responsible for both motor and cognitive symptoms. Recently, it has been suggested that progressive supranuclear palsy tauopathy may spread in the brain from cell ...

Wide-field imaging of cortical neuronal activity with red-shifted functional indicators during motor task execution

Silvestro Micera, Francesco Saverio Pavone, Maria Pasquini

Genetically encoded calcium indicators (GECIs) can be used to monitor the intracellular concentration of free calcium in populations of neurons. GECIs with long emission wavelengths are particularly attractive for deep tissue microscopy in vivo, and have t ...

EEG topographies provide subject-specific correlates of motor control

José del Rocio Millán Ruiz, Dimitri Nestor Alice Van De Ville, Elvira Pirondini, Silvestro Micera, Martina Coscia, Jesús Minguillón Campos

Electroencephalography (EEG) of brain activity can be represented in terms of dynamically changing topographies (microstates). Notably, spontaneous brain activity recorded at rest can be characterized by four distinctive topographies. Despite their well-es ...
