This is available as a power point demonstration on the course hyperlinks What you will learn in this module 1. You will learn that the firing pattern of a neural circuit are shaped by. 1) connectivity, 2) synaptic properties, and 3) intrinsic cellular properties 2. You will learn that the behavior of two interconnected neurons is strongly determined by the type(s) of receptor on the post- and presynaptic neuron. 3. You will learn about rhythm generating circuits that are ubiquitous across invertebrate and vertebrate motor systems. 4. You will learn example(s) of cellular properties that shape the firing pattern of a neural circuit. Small Circuits Lectures a. Connectivity b. Synaptic Properties Accommodation, habituation, transmitter limitations Synaptic currents and voltage, or ion gating Variability in strength of synapses Multi-component PSPs Second messenger effects of metabotropic receptors Can be due to either multiple transmitters or More than one effect over time of the same xmitter c. Intrinsic Cellular Properties Endogenous spontaneous activity Some forms of post-inhibitory rebound

A B A B time vol tage time Each line on the plots represent an action potential Excitatory neuron and synapse Monosynaptic Excitation: B has no spontaneous activity Inhibitory neuron and synapse V.A.2.a. Cell B has spontaneous activity Note on the next few slides you will see multiple plots. The x axis is time and the y axis is voltage. Each vertical line represents a cell firing an action potential.
