The basal ganglia are a subcortical collection of interacting clusters of cell bodies, and are involved in reward, emotional, and motor circuits. Within all the brain processing necessary to carry out …

Positioned at the base of the forebrain and the top of the midbrain, they have strong connections with the cerebral cortex, thalamus, brainstem and other brain areas.

One way to think of the basal ganglia is like a circuit board found in an electronic device. The ganglia form connections and circuits with different parts of your brain, allowing them to send signals back …

Oct 30, 2023 · Three major pathways emerge from the basal ganglia, which project onto various structures of the brain, communicating with them. They are called the direct (excitatory), indirect …

The basal ganglia are now appreciated as components of parallel, reentrant cortico-subcortical circuits, which originate from individual cortical areas, traverse the basal ganglia and thalamus, and terminate …

Nov 6, 2025 · The arterial supply to the basal ganglia comes mainly from the middle cerebral artery, a continuation of the internal carotid artery. The main artery is named lenticulostriate artery and, as the …

Aug 8, 2025 · Neuroscientists describe the basal ganglia’s main circuitry as a set of parallel loops. Each loop starts and ends in the cortex but takes a detour through the basal ganglia and the thalamus.
