Membrane potential changes in rat SmI cortical neurons evoked by controlled stimulation of mystacial vibrissae

Brain Res. 1988 May 10;448(1):186-91. doi: 10.1016/0006-8993(88)91118-3.


Intracellular recordings from rat somatic sensory vibrissa/barrel cortex demonstrate that whisker displacements evoke short latency excitatory postsynaptic potentials followed by longer lasting inhibitory potentials. The time course and whisker-related spatial distribution of the potentials represent synaptic correlates of the integration of whisker inputs observed in extracellular studies.
