Striatum - Wikipedia
The striatum is the largest structure of the basal ganglia. The striatum is divided into two subdivisions, a ventral striatum and a dorsal striatum, based upon function and connections.

2023年10月30日 · The striatum is the main input unit of the basal ganglia. It receives excitatory glutamatergic inputs from the cerebral cortex, whose synapsing pattern reflects the topography of the cortex.
Basal ganglia - Wikipedia
The main functional components of the basal ganglia include the striatum, consisting of both the dorsal striatum (caudate nucleus and putamen) and the ventral striatum (nucleus accumbens and olfactory tubercle), the globus pallidus, the ventral pallidum, the substantia nigra, and the subthalamic nucleus.

Basal ganglia for beginners: the basic concepts you need to know …
The striatum is the main region for inputs to the basal ganglia, receiving several projections from the cortex, thalamus, and brainstem. The cortico-striatal projections exert the greatest influence on the striatum through glutamatergic synapses, they are mostly excitatory.
Basal Ganglia – Foundations of Neuroscience - Michigan State …
The majority of information processed by the basal ganglia enters through the striatum. The principal source of input to the basal ganglia is from the cerebral cortex.

2023年7月24日 · The largest component of the basal ganglia is the corpus striatum which contains the caudate and lenticular nuclei (the putamen, globus pallidus externus, and internus), the subthalamic nucleus (STN), and the substantia nigra (SN).
The Basal Ganglia: More than just a switching device - PubMed …
The striatum, a major basal ganglia component, is particularly useful for cognitive planning of purposive motor acts owing to its structural features and the neuronal circuitry established with the cerebral cortex. Recent data indicate emergent functions played by the striatum.
Basal Ganglia (Section 3, Chapter 4 ... - Texas Medical Center
The basal ganglia comprise a distributed set of brain structures in the telencephalon, diencephalon, and mesencephalon (Figure 4.1 and Table 1). The forebrain structures include the caudate nucleus, the putamen, the nucleus accumbens (or …
Biochemical Anatomy of the Basal Ganglia and Associated Neural …
The direct path is composed of GABAergic inhibitory fibers from the striatum to the internal or medial globus pallidus (GPm) and to the substantia nigra pars reticulata (SNr), the main efferent nuclei of the basal ganglia.
Projections to the Basal Ganglia - National Center for …
The basal ganglia are divided into several functionally distinct groups of nuclei (Figure 18.1). The first and larger of these groups is called the corpus striatum, which includes the caudate and putamen.
