Antidromic Response - answer✔Stimulate postsynaptic axons, observe cell body response
Sharp Microelectrode - answer✔fine glass tip filled with strong salt. DC coupled amplifier.
Sub-threshold activity.
Wheatstone Bridge - answer✔balances resistances of pipette and bridge to neutralize effect of
pipette resistance. Initial response reflects only cell membrane properties.
Cell-autonomous Bursting - answer✔rhythmically depolarize even after isolation
Network Based Burst - answer✔Two tonic or no activity cells if active generate rhythm due to
mutual antagonist synaptic inhibition (inhibitory synapses)
Command Neuron - answer✔Tonic firing neuron, sensory input to get a not intrinsically
rhythmic circuit going
Trigger Neuron - answer✔Trigger rhythmicity of network.
Snail CPG - answer✔RPeD1, VD4, IP3I
IP31 - answer✔activation of VI/J
RPeD1 - answer✔Destroy CB, CPG fin for awhile. All signaling in dendrite and axons, only
ITM is shown, no LTM.
STG - answer✔CPG, STG, STNS
Gastric Mill CPG - answer✔Gpn, agn, lpgn, dgn
bursting irregular (except gpn), phasic relationship between them
Pyloric CPG - answer✔Pdn, avn, lpn, pyn, myn (AB, PD, LP, PY)
faster then mill, regular bursting with phasic relationships
AB and PD connected by gap junctions. Depolarization in AB/PD lead to LP hyperpolarization.
Protein Kinases - answer✔CaMKII and PCK: activation induce LTP
MAPK: activated by LTP, inhibit late gene expression
PKA and Tyrosine Kinase: specific pathways
Feedback Somatic Inhibition - answer✔output axon excites interneuron that feedback and
inhibit CB
Feedforward Somatic Inhibition - answer✔Input axon excites inhibitory interneuron prior to
pyramidal neuron inhibiting CB. Curtail early excitation.
