Study Notes
Functional Neuroanatomy
- Brodmann's Areas consist of 47 distinct cytoarchitectonic regions that categorize brain functions.
- Hemispheric lateralization shows the division of labor between the left and right hemispheres affecting cognitive and emotional processing.
Language Localization and Processing
- Language predominantly resides in the left hemisphere, which is crucial for core language functions.
- Attention is managed by the right frontal lobe, with ADHD associated with reduced metabolism in frontal lobes.
- The left hemisphere handles analytical tasks with a limited emotional response, while the right hemisphere excels in affect and socialization.
Neural Pathways and Sensory Processing
- Neural impulses generated in the brain travel along axons of sensory nerves to various brain regions.
- Olfactory signals are processed through the cribriform plate, connecting the olfactory system to the nucleus solitarius.
- Odorants dissolve in nasal mucus and bind to specific receptors on sensory neurons located in the olfactory epithelium.
Autonomic Nervous System Functions
- The sympathetic system triggers the "fight or flight" response, enhancing alertness and preparedness for action.
- The parasympathetic system counteracts stress by reducing heart rate and initiating calm behaviors.
- Soluble chemical cues are vital for olfactory sensation, influencing behavior and physiological responses.
