Document Summary
Here, all the synaptic connections had excitatory effects. This chemical passes the synaptic gap and can either excite or inhibit subsequent neurons: cytoplasm: jelly-like substance inside the cell. Inside are the mitochondria, which use glucose to produce energy: the mitochondria produce a chemical called adenosine triphosphate (atp) which is used as an energy source. Glial cells (glia, collectively): provide support and assistance with chemical transport to and from neurons, as well as destroy and remove neurons that are dead (either from old age or injury). 70 mv: this is called the resting membrane potential, this charge changes when a signal is sent down the neuron, depolarisation: when something goes from an extreme value to a less extreme value (closer to zero) If we pass a positive current into the neuron via an electrode placed in the cell body, this decreases the negative charge, thus depolarising.
