Fig. 6From: Stimulation-induced structural changes at the nucleus, endoplasmic reticulum and mitochondria of hippocampal neuronsStimulation-induced clustering of chromatin is calcium-dependent. In dissociated hippocampal cultures, the NMDA-induced clustering of chromatin (a) was blocked by APV (b). The depolarization-induced clustering of chromatin (c) was blocked by chelation of extracellular calcium with EGTA (d). Scale bar = 0.5 μmBack to article page
