Via directa proceso:

A

Directa: info cortical al putamen con aferencias +, inhiben a las inhibidoras y termina en globo palido interno y activan inhibidoras que van al talamo y se hacen +

Q

Via indirecta proceso:

A

Info cortical llega al putamen con aferencias positivas e activa a las inhibidoras en globo palido externo y las que van al nucleo subtalamico y al talamo= activan inhihibidoras

16
Q

Que hace el nucleo subtalamico?

A

manda aferencias _+ al globo palido interno, activando inhibidoras
-Controla via directa
