A neurophysiologist research on the functional properties of various R/eceptor subtypes, using whole cell voltage clamp recordings made from coronal brain slices. At a holding potential of -70mV, bath application of R agonists for four different R types consistently elicited either excitatory post synaptic currents or inhibitory past synaptic currents. During the study of one R, however, agonist application failed to elicit a post synaptic response at – 70 mV but did elicit a reliable response at a holding potential of 0 mV. This R is most likely which of the following? [ http://i.imgur.com/6hDHdim.png?1]
a)GABA/a
b)Kainate
c)N-methyl-d-aspartate
d)Nicotinic Ach
e)5-HT3
