The main objective of the course is understanding the structural and functional concepts characterising neuronal networks.The course covers the following topics: Membrane characteristics of neurons. The action potential. The synaptic transmission. Synaptic plasticity. Techniques applied in electrophysiology. Motor control by the spinal cord: reflexes and locomotion. Descending supraspinal motor control. Voluntary and involuntary movements. Role of the cerebellum in motor co-ordination. Brain-machine interfaces. Receptors in the olphactory epithelium. Neuronal networks and function of the olphactory bulb. Structure of retina. Visual information processing in the retina, thalamus, and the visual cortex (demonstration of electrophysiological recordings from the visual cortex). The receptive field. Detection of movement, colour and contour. Function of the auditory cortex (demonstration of electrophysiological recordings from the auditory cortex). Thalamocortical neuronal networks. Information processing in thalamus. EEG. Neuronal connections of the hippocampus. Neuronal communicatio
n in the hippocampus. Role of the principal neurons and the inhibitory interneurons.
Feedback and feed forward inhibition. Theta activity: mechanism and function. The binding problem: role of gamma oscillation. Molecular mechanism of memory. Learning at cellular and network levels. Behavioural aspects of learning and memory. Computational modelling of neuronal networks. Localization of cognitive processes in the brain. Functional brain mapping. Functional imaging methods (video-demonstration of functional imaging techniques; PET, fMRI). Symptoms of neurological diseases. Pathomechanism of epilepsy. Anxiety and depression. Neurosurgery. The hypothalamo-hypophyseo-peripheral gland system. The magno- and parvocellular system. Regulation of adaptation and metabolism. Neurobiology of reproduction.
