Module: FISIOLOGIA DEI SISTEMI COMPLESSI
-------
The student will learn the molecular mechanisms that underlie integrated functions, with particular regard to those performed by excitable and endocrine cells. The student will be able to describe and interpret the energy transformations and the structural correlates subtending the physiological processes at the different levels of organization, to understand and generalize the signaling mechanisms for the integration and the homeostatic control of physiological variables.

-------
During the course we will examine the main methods for data collection and signal processing used in basic and applied physiological research, as well as the theoretical reference models. With particular regard to the domain of cognitive neuroscience, we will consider different experimental contexts and for each some real study cases will be discussed.

-------
• Cardiovascular System: Features and functions of systemic and pulmonary circulation. Features and functions of the vascular system. Mechanical activity of the heart. Adjustment of cardiac output. Regulation of systemic blood pressure.
• Respiratory System: Mechanics of breathing. Gas exchange in lungs and tissues. Transport of oxygen and carbon dioxide in the blood. Regulation of breathing.
• Renal system: Glomerular ultrafiltration. Tubular reabsorption and secretion. Regulation of the composition of extracellular fluid. Regulation of acid-base balance.
• Nervous system: Peripheral and central nervous system. Sensory system: receptors, transduction, "specific nerve energies." Sensory units. Encoding of location, intensity and duration. Somatic sensibility: receptors, spinal systems, morphofunctional organization of the cortex. Vision: references to physics and physiological optics, refractive errors, visual field, structure of the retina, phototransduction, organization of receptive fields in the retina, subcortical projections, morphofunctional organization of the cortex. Hearing: references to physical acoustics, travelling wave, transduction in hair cells, central pathways, organization of the cortex. Motor system: reflex arc. Spinal reflexes. Superior control of reflex activity. Descending brainstem pathways and corticospinal tract. Organization of motor and premotor cortex. Autonomic nervous system. Effects of ortho- and parasympathetic stimulation on various organs.
• Endocrine System: Integration of hypothalamic and limbic system. Relationships between the hypothalamus and the pituitary gland. Posterior and anterior pituitary hormones. Hormones of the thyroid, parathyroid glands, adrenal gland and pancreas.
