Assume that a single IPSP has a negative magnitude of -0.5 mV at the axon hillock, and that a single EPSP has a positive magnitude of +0.5 mV. For a neuron with an initial membrane potential of -70 mV, the net effect of the simultaneous arrival of six IPSPs and two EPSPs would be to move the membrane potential to

Neurons communicate with each other at junctions called synapses. The neuron that sends the signal is called the presynaptic neuron, and the neuron that receives the signal is called the postsynaptic neuron.  Neurons communicate using both electrical and chemical signals: Electrical signals: Sensory stimuli are converted to electrical signals, which are carried along neurons as action potentials. Chemical signals: In most synapses, chemical messengers are released to communicate using chemical messengers.  Synapses can be classified into three types based on anatomy: Axoaxonic synapses:...

Neurons communicate with each other at junctions called synapses. The neuron that sends the signal is called the presynaptic neuron, and the neuron that receives the signal is called the postsynaptic neuron. 

Neurons communicate using both electrical and chemical signals:
Electrical signals: Sensory stimuli are converted to electrical signals, which are carried along neurons as action potentials.
Chemical signals: In most synapses, chemical messengers are released to communicate using chemical messengers. 

Synapses can be classified into three types based on anatomy:
Axoaxonic synapses: The axons of two different neurons meet.
Axodendritic synapses: The axon of one neuron terminates on the dendrite of another neuron.
Axosomatic synapses: The axon of one neuron attaches to the soma (cell body) of another neuron. 

Synapses can also be classified into two types based on function or physiology:
Electrical synapses: These are faster than chemical synapses.
Chemical synapses: These are more common.
