Is the rostro caudal axis of the frontal lobe hierarchical?
Is the rostro caudal axis of the frontal lobe hierarchical?
Data from effective connectivity analysis of functional MRI data in humans suggests a rostral-to-caudal flow of influence, which is indirectly consistent with a rostro-caudal hierarchy of processing. Non-adjacent regions follow an asymmetry principle from rostral to caudal within the frontal cortex.
What is the Rostrocaudal axis?
Similarly, the term “caudal” is used more in embryology and only occasionally used in human anatomy. This is because the brain is situated at the superior part of the head whereas the nose is situated in the anterior part. Thus, the “rostrocaudal axis” refers to a C shape (see image).
Which area is the apex of the frontal control hierarchy?
anterior mid-DLPFC
We propose that anterior mid-DLPFC, rather than RLPFC, is the apex of the frontal control hierarchy (Fig. 4). RLPFC is best characterized as a domain specific frontal region, with a role analogous to caudal domain-specific frontal regions.
What does the frontal lobe coordinate?
The frontal lobe is involved in reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production.
Where is the lateral frontal cortex?
A Lateral. The lateral prefrontal cortex is the prefrontal cortex of the lateral convexity of the frontal lobe (Figure 5.7). It comprises part or the entirety of areas 8, 9, 10, and 46.
Which structure is located in the frontal lobe?
The frontal lobe is covered by the frontal cortex. The frontal cortex includes the premotor cortex, and the primary motor cortex – parts of the motor cortex. The front part of the frontal cortex is covered by the prefrontal cortex.
Which of the following areas is located in the frontal lobe of the brain?
The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe is involved in reasoning, motor control, emotion, and language.
Are anterior and posterior the same as dorsal and ventral?
Anterior (or ventral) Describes the front or direction toward the front of the body. Posterior (or dorsal) Describes the back or direction toward the back of the body. The popliteus is posterior to the patella.
What are the difference between anterior and posterior?
The difference between anterior and posterior is simple: anterior means near or towards the front of something and posterior means near or towards the back. When taking a posterior approach, the surgeon will usually make a midline incision or off to the side, approaching the spine from more the back of the neck.
