Unformatted text preview: a. Connectivity b. Synaptic Properties these will be more clear later 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 V.A.1 Properties that determine circuit behavior A B A B time voltage voltage 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 A B A B Each line on the plots represent an action potential Excitatory neuron and synapse Monosynaptic Excitation with Amplification Inhibitory neuron and synapse voltage voltage time time V.A.2.b. Amplifying synapse Spontaneous Activity 1) Random fluctuations in channels 2) Inputs from areas you are not looking at For example if you record from visual cortex, spontaneous activity can be due to changes in activation of attention related parts of the brain that are not effected by light A B A B Each line on the plots represent an action potential...
