Neuron Function 2
... 1. An arriving action potential depolarizes the synaptic knob 2. Ca+2 ions enter the cytoplasm of the synaptic knob. 3. ACh release occurs through diffusion and exocytosis of neurotransmitter vesicles 4. ACh diffuses across the synaptic cleft and binds to receptors on the postsynaptic membrane. ...

High-speed CCD movie camera with random pixel selection,
... Laser-scanning systems for voltage-sensitive dye recording have been developed by two groups (Morad et al., 1986; Saggau, 1994). These employ acousto-optic deflectors to rapidly steer a laser excitation spot to user- selectable regions in the specimen. Fluorescence is detected by a single photodiode ...
