This summary is for the first written exam of the medical minor Translational Neuroscience (Med-Min16). The lectures are summarized that are needed for the first exam. Included are pictures to help with grasp everything.
, Rhombencephalon → fourth ventricle (between metencephalon & myelencephalon)
Metencephalon → cerebellum (compare info from SPC and how it’s planned, can
correct) & pons (bridge cerebellum & cortex, nuclei of cranial nerve V)
Motor system → crossing fibres from and to cerebellum
Inferior cerebellar peduncle → connects cerebellum to medulla
Middle cerebellar peduncle → connects cerebellum to pons
Superior cerebellar peduncle → connects cerebellum to mesencephalon
Myelencephalon → medulla, cranial nerves VI-XII, sensory, motor & visceral nuclei
Spinal cord → central canal
Meninges (membranes) → Dura mater (tough), Arachnoid (spidery) & Pia mater (soft)
Superior cerebral veins beneath arachnoid
Primary visual cortex → occipital lobe
Primary auditory cortex → temporal lobe
Wernicke’s aphasia = lesion next to left auditory cortex
(weird sentences)
Motor cortex → frontal lobe
Sensory cortex → parietal lobe
Prefrontal cortex → frontal lobe
Broca’s aphasia = lesion to left frontal cortex (can’t say what u want)
Motor cortex thicker than sensory due to pyramidal neurons
Layer I → molecular
Layer II & III → cross integration small pyramidal
cell
Layer IV → afferent fibres from thalamus
Layer V → large pyramidal cells (motor
projection to brainstem & Sp cord)
Layer VI → projections to thalamus
(corticothalamic, pyramidal tract,
thalamocortical, short association &
cholinergic/aminergic)
