摘要: Spontaneous activity and responses to sensory stimulation in ventrobasal (VB) thalamic neurons were studied barbiturate-anesthetized rats through intracellular recordings. The recordings carried out with micropipettes filled K acetate, KCl plus horseradish peroxidase (HRP), our biocytin. Two types of spontaneous depolarizing events observed: fast potentials (FPs), characterized by a low amplitude (5.3 ± 1.8 mV [mean standard deviation]), rising slope (1.15 0.19 msec), short duration (8.47 0.89 msec); slow (SPs), larger more variable (9.1 5.6 mV) longer (62.5 27.2 slower (26.2 6.4 msec). potential changes elicited stimuli delivered manually similar those electronically gated air jets the receptive fields. FPs evoked 62.7% recorded neurons, SPs remaining 37.3%. Both of...
