How many neutrons |
86 billion :] |

|
Connexon |
The foundation of electrical synapses. Channel between neurons. |
|
|
Two advantages of electrical synapses |
1) Near instant potential transmission 2) Bidirectionality -> synchronisation of neurons in f.e. the breathing system modulated by the brainstem |
|
|
Two classes of neurotransmitters |
Small molecule: generally synaptic Neuropeptides: generally general :D |
|
|
Co-transmitters |
Two different transmitters from same neuron. Released differently based on things like pattern of synaptic activity. |
|
|
Neuropeptide vs small-molecule vesicles |
Small clear-core vesicles: 40-60nm, not electron dense; synthesized partly in soma, then finished by presynaptic enzymes Large dense-core vesicles: 90-250nm, electron dense; synthesised in cell body |
|
|
Cleaning a synapse |
Glial cells or enzymatic degradation |
|
|
HRP peroxidase experiment and conclusion |
