The parallel CBGTC loops have been segregated according to the functions of associated cortical regions. One scheme involves the division into limbic and motor loops, with the motor loops containing indirect and direct pathways, which are in turn interconnected with the limbic loop that projects into the ventral striatum.

The indirect pathway, sometimes known as the indirect pathway of movement, is a neuronal circuit through the basal ganglia and several associated nuclei within the central nervous system (CNS) which helps to prevent unwanted muscle contractions from competing with voluntary movements. [1] It operates in conjunction with the direct pathway.
The direct pathway, sometimes known as the direct pathway of movement, is a neural pathway within the central nervous system (CNS) through the basal ganglia which facilitates the initiation and execution of voluntary movement. [1] It works in conjunction with the indirect pathway.
The indirect pathway is responsible for the termination of movement. The indirect pathway inhibits unwanted movements by simultaneous increase in excitatory input to other GPi and SNr neurons. [4] Similar to the direct pathway, the indirect pathway is regulated by striatal dopamine. D 2 dopamine receptors inhibit transmission via the indirect ...
The balance of direct/indirect activity in movement is supported by evidence from neurodegenerative disorders, including Parkinson's disease (PD), which is characterized by loss of dopamine neurons projecting to the striatum, hypoactivity in direct pathway and hyperactivity in indirect pathway neurons, along with motor dysfunction.

In his first sit-down broadcast interview since the Nov. 5 election, President-elect Donald Trump said he would begin pardoning rioters who participated in the Jan. 6 attack on the U.S. Capitol on ...
The substantia nigra is located in the ventral midbrain of each hemisphere. It has two distinct parts, the pars compacta (SNc) and the pars reticulata (SNr). The pars compacta contains dopaminergic neurons from the A9 cell group that forms the nigrostriatal pathway that, by supplying dopamine to the striatum, relays information to the basal ganglia.
