6/11/11 1 Neuronal control Introduction to neural control Structure of the nervous system Neuronal membrane potentials Synapses and communication Receptors of the sensory system 05 The goal of this lecture is to discuss basic neuronal control issues by introducing concepts associated with the structure - function of the neurolemma, membrane potentials, synapses and sensory receptors. The sections for this lecture are: Life is a series of chemical reactions occurring in compartmentalized environments. The main purpose of life is to keep itself alive Physiology, the study of how life works, is based on the simultaneous occurrence of the following three concepts: levels of organization structure / function relationship homeostatic regulation (think in the “slap in the face” example as a lecture map) Neuronal control Introduction nervous and endocrine talk neuronal / glial cell structure central, peripheral, autonomic ligand / voltage gated channel Membrane Potentials diffusion potential equilibrium potential resting membrane potential graded and local potentials membrane threshold action potential variable membrane potential in pacemaker cells Synapses electric and chemical excitatory and inhibitory temporal / spatial summation pre-synaptic inhibition pre-synaptic facilitation synaptic transmission Sensory System sensory system information receptors and its potential sensory neural pathways association cortex and perceptual processing look for the “slap in the face” example and for the “boy sees girl” example as learning tools
