BA10 was originally defined broadly in terms of its cytoarchitectonic traits as they were observed in the brains of cadavers, but because modern functional imaging cannot precisely identify these boundaries, the terms anterior prefrontal cortex, rostral prefrontal cortex and frontopolar prefrontal cortex are used to refer to the area in the ...
In the human brain, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24 , 32 , and 33 .
Cortex Primary visual cortex (V1) V2; V3; V4; Gyri. Lateral occipital gyrus; Other Cuneus; Brodmann areas 17 (V1, primary visual cortex); 18, 19; Temporal lobe. Cortex Primary auditory cortex (A1) Secondary auditory cortex (A2) Inferior temporal cortex; V5/MT; Posterior inferior temporal cortex; Gyri. Superior temporal gyrus; Middle temporal ...
The rostral spinocerebellar tract is a tract which transmits information from the golgi tendon organs of the cranial half of the body to the cerebellum. [8] It terminates bilaterally in the anterior lobe of the cerebellum (lower cerebellar peduncle) after travelling ipsilaterally from its origin in the cervical portion of the spinal cord.
The function of the cerebellar cortex is essentially to modulate information flowing through the deep nuclei. The microcircuitry of the cerebellum is schematized in Figure 5. Mossy and climbing fibers carry sensorimotor information into the deep nuclei, which in turn pass it on to various premotor areas, thus regulating the gain and timing of ...
The modulatory functions are primarily found in the rostral sector of the reticular formation and the premotor functions are localized in the neurons in more caudal regions. The reticular formation is divided into three columns: raphe nuclei (median), gigantocellular reticular nuclei (medial zone), and parvocellular reticular nuclei (lateral zone).
The cerebellum develops in a rostro-caudal manner, with rostral regions in the midline giving rise to the vermis, and caudal regions developing into the cerebellar hemispheres. [2] By 4 months of prenatal development, the vermis becomes fully foliated, while development of the hemispheres lags by 30–60 days. [3]
The basal ganglia are located bilaterally, and have rostral and caudal divisions. The putamen is located in the rostral division as part of the striatum. The basal ganglia receive input from the cerebral cortex, via the striatum. This is a transverse section of the striatum from a structural MR image.
