What does the change in membrane voltage depend on? - ️️depends on the ion channels opened, not the neurotransmitter some neurotransmitters can have both excitatory and inhibitory effects; depends on the ligand gated channels in postsynaptic cell and the ion channels determining EPSP or IPSP When are large axons used? - ️️rapid responses- cockroach startle/escape response; sensory filiform hair receptors on back synapse to giant axon that goes to thoracic region and then synapses ...

What is bird song, and why is it important to a bird? - -complex vocalization typically produced by a male in possession of a breeding territory -used to defend territory and attract females What kinds of birds learn to sing, and which species are commonly used in studies of bird song learning? - -songbirds, hummingbirds, and parrots -white-crowned sparrows and zebra finches are commonly studied Why study bird song? What are the features of song learning that make it an appropriate model...

Based on Question 5: Know the typical electrical and concentration/chemical gradients that exist across the plasma membrane of a neuron for Na+, K+ and Cl-. Based on these gradients, be able to state what direction each ion moves across the membrane - -[Na+]out >> [Na+]in -[K+]out << [K+]in -Differences maintained by Na+ K+ ATPase pump; 3 Na+ ions out, 2 K+ ions in, creates a net loss of positive ions -resting membrane potential is -50 to -80 mV -for K+ and Cl-, concentration and...

Why is the speed of an action potential important? resting potential, action potential increase in membrane voltage, and action potential duration are about the same in all organisms, but action potential speed varies greatly speed is a limiting factor; things need to be processed in biologically relevant time and propagation speed limits how big an organism can be and how complex faster conduction allows for larger size humans would not have developed their size or comp...
