Study Notes
Anatomy and Functional Localization in the Brain
- Cerebrospinal fluid (CSF) circulation involves the choroid plexus, arachnoid granulations, dural venous sinuses, and lymphatics.
- MRI can be used to visualize normal ventricles and those affected by hydrocephalus.
- The cerebral cortex receives sensory input and produces motor output, with dedicated areas for different sensory modalities and interpretation.
- The major sulci and gyri of the cerebral hemispheres can be identified in lateral and superior views.
- The lobes of the cerebral hemisphere are the frontal, parietal, temporal, and occipital lobes.
- Functional localization in the cerebral cortex involves the primary motor cortex, premotor cortex, primary somatosensory cortex, and somatosensory association cortex.
- The primary visual cortex, visual association cortex, primary auditory cortex, and auditory association cortex are involved in visual and auditory perception.
- The motor speech area (Broca's area), primary gustatory cortex, and primary olfactory cortex are responsible for speech, taste, and smell perception.
- Multimodal association cortices, such as the prefrontal cortex and inferior parietal lobe, integrate information from various association cortices.
- The basal nuclei, including the caudate, putamen, globus pallidus, and substantia nigra, refine normal voluntary movement and are associated with diseases like Parkinsonism.
- The diencephalon, consisting of the thalamus, hypothalamus, and epithalamus, has functional organization of nuclei for sensory, motor, and limbic functions.
- The thalamus has sensory, motor, and limbic nuclei, while the hypothalamus regulates emotions, mood, and other autonomic functions.
