Knowledge
- The course is organized around different neuroanatomical and neurobiological aspects of the organization and function of sensory and motor systems of the brain.
- At the end of the course, the students will have acquired critical instruments to understand the general patterns of organization of the central nervous system and the main mechanisms of sensory processing and organization of the motor outputs. The course gives the students the opportunity to meditate on the acquired neurobiological knowledge to link the activity of nerve cells and of the sensory and motor systems of the brain with the generated behavioral output.
Assessment criteria of knowledge
- The knowledge acquired by the student during the course will be assessed during the final examination.
Skills
- At the end of the course, the student will be able to understand how the behavior of an animal is linked and is produced by the integrated activities of different neuronal populations in the brain.
Assessment criteria of skills
- The skills acquired by the student during the course will be assessed during the final examination.
Prerequisites
- Physiology of neuron and synapse. Generalities on the sensory and motor systems in the brain.
Teaching methods
- Face to face delivery with Power Point presentations
- A link to download the presentations is available at the elearning site of the course
- For information and appointments, contact the teachers

Brain hemispheres: main sulci; definition of the different lobes. Overview of the brainstem; external features (naming only elements shown in the slides provided): ventral view, dorsal view. Identifying and naming main nuclei and bundles from sections of mesncephalon, pons and medulla oblungata (only those mentioned in slides).
- Gross anatomy of the human spinal cord: External features. Denticulate ligaments; cervical and lumbar enlargement; relation of spinal cord myelomeres and spinal nerves with segments of the vertebral column. Spinal cord meninges. Main features of spinal nerves.
- Structure of the spinal cord: laminar and nuclear organization of gray matter including detailed description of the types of neurons, afferents and efferents. Ventral and dorsal radicular cells, funicular cells; ascending bundles of spinal cord white matter. Site of termination of afferent fibers of different sizes into the spinal cord grey matter.
- Sensitive pathways: brief overview of skin, joint and tendon receptors (muscle spindles only mentioned). Dorsal column-medial lemniscus pathways; dorsal column nuclei sensu strictu, and extended definition of dorsal column nuclei. Spino-cerebellar tracts. Spino-thalamic system: site of origin in the spinal cord; concepts of paleo- and neo-spinothalamic system. Trigeminal system: mesencephalic, pontine and spinal trigeminal nucleus.
- Thalamus: general features. Reticular thalamic nucleus: specific features and connections. Gross anatomy: details on the different nuclei, basic cytological and functional organization: classical view (relay, association and intralaminar/midline nuclei) and more recent one (first-order and higher-order nuclei). Detailed description of VPL; connections with the Iry and IIry sensory cortex.

Non-attending students info
- There are no particular indications for non-frequenting students. For information or elucidations (on the course organization or on lecture contents), please contact the professors at the following email addresses: maya.vetencourt@unipi.it; filippo.giorgi@unipi.it; giovanni.casini@unipi.it.
Assessment methods
- Oral exam. This exam consists of a conversation between the student and the examiner of approximately 30 – 45 minutes. This exam is not passed if:
- the student does not speak clearly and using appropriate terminology.
