12. Basal Ganglia & Cerebellum - Orman

Explanation
4) Subthalamus (diencephalon'da) 5) Substantia nigra (Midbrain'de)

Explanation
The cerebellum is responsible for coordinating voluntary movements and maintaining balance. It sends excitatory signals to the motor cortex, enhancing the activity of the muscles involved in movement. On the other hand, the basal ganglia play a role in regulating movement by inhibiting certain motor pathways. Therefore, the statement that the output of the cerebellum is excitatory, while the basal ganglia are inhibitory is true.

Explanation
The statement is true because the lentiform nucleus, also known as the lenticular nucleus, is composed of two structures: the putamen and the globus pallidus (GP). These structures are located deep within the brain and play important roles in motor control and movement. The putamen is involved in motor planning and execution, while the globus pallidus helps regulate movement by inhibiting certain motor pathways. Therefore, it is correct to say that the lentiform nucleus is made up of the putamen and globus pallidus.

Explanation
The statement is true because the neostriatum, also known as the striatum, is indeed composed of two structures: the caudate nucleus and the putamen. These two structures are interconnected and together form the major input region of the basal ganglia.

Explanation
The given answer is true because it directly corresponds to the question. The question asks whether the statement provided is true or false, and the answer states that it is true.

Explanation
Tegmentum öndeki midbrain kismi. Tectum cerebral aqueduct arkasında sup. ve inf. collicus'larin meydana getirdigi kisim. Tegmentum-thalamus arasinda thalamus altindadir subthalamus.

Explanation
Basal ganglia'ya bilgi geliyorsa bu ikisine gelir. Giren bilgi anlaminda-input nuclei'dir. Output bilginin ciktigi cekirdekler.

Explanation
The flocculonodular lobe is considered the oldest (evolutionarily) lobe of the three cerebellar lobes. It is also known as the archicerebellum. This lobe is responsible for maintaining balance and coordinating eye movements. Its evolutionary significance lies in its role in basic motor functions, which are believed to have developed early in the evolution of vertebrates. Therefore, the statement "Flocculonodular lobe is the oldest (evolutionarily) lobe of the three cerebellar lobes" is true.
