Stimulus-Evoked Calcium Transients in Somatosensory Cortex are Inhibited After a Nearby Microhemorrhage

Not Accessible

Your library or personal account may give you access

Abstract

We use femtosecond laser pulses to hemorrhage brain arterioles and then study changes in cell-resolved calcium transients using two-photon microscopy. We find that microhemorrhages lead to a loss of stimulus-evoked response in nearby neurons.
