| A. 4. Primary motor cortex sends writing motor plans to the dominant hand. B. 2. Broca’s area projects to the supplementary motor area (SMA; top of area 6), which activates speech plans. C. 3. The thalamus relays the information to the primary auditory cortex (PAC) for signal processing. D. 1. Visual information is projected to the thalamus’s lateral geniculate nucleus (LGN) via the optic tracts. E. 4. The PAC routes to Wernicke’s area for meaning attachment. F. 5. The left superior parietal lobe coordinates the visuouspatial elements of writing. (There are visuouspatial elements to writing – you can’t write it all in one space.)G. 2. Language-encoded thoughts sent to premotor cortex (BA 6; Exner’s area) for handwriting motor planning. H. 1. The ear converts acoustic energy into electrochemical energy and transmits it to the brainstem’s cochlear nuclear complex (CNC) via cranial nerve VIII. I. 3. Motor plans sent to the primary motor cortex. J. 5. Wernicke’s area projects to Broca’s area for higher-level syntactical processing.
(Even silent reading reading activates auditory cortex.)
K. 2. The thalamus projects back to the occipital lobe’s visual areas (BA 17–19) for visual processing via the geniculocalcarine tract. L. Aud. Comp (corresponds with reading) - Verbal production (corresponds with writing) - Repetition - Naming (word finding/retrieval is poor for all types)
M. 3. The visual areas project a dorsal stream of vision (i.e., the “where”) and a ventral stream of vision (i.e., the “what”). When reading, the anterior, parietotemporal, and occipitotemporal reading systems activate. N. 1. Desire and thoughts originate in the prefrontal cortex, which is sent to Broca’s area for language encoding. O. 3. SMA relays now active plans to the primary motor cortex.P. 2. The CNC sends this information to the thalamus. Q. 4. Primary motor cortex sends plans to the speech muscles for execution.R. 1. Desire and thoughts to communicate originate in the prefrontal cortex and are sent to Broca’s area for language encoding and speech planning. |
