Comparison of Electrical and Chemical Synapses
Electrical and chemical synapses differ in terms of speed and prevalence. Electrical synapses are significantly faster because they allow electrical current to pass directly between cells. However, they are far less numerous in the brain than the more common chemical synapses.

Gap Junctions in Electrical Synapses
Comparison of Electrical and Chemical Synapses
A researcher is studying a neural circuit responsible for a rapid escape reflex in an invertebrate. This reflex requires a group of neurons to fire in almost perfect synchrony to ensure the fastest possible response. Which of the following intercellular connection designs would be most advantageous for this specific function?
A neural circuit in an organism controls a critical escape reflex. This reflex must be extremely fast and involve the simultaneous contraction of several muscles. The neurons in this circuit are joined by connections that permit electrical current to pass directly from one cell to the next. Based on this mechanism, evaluate the effectiveness of these connections for this specific reflex.
Comparison of Electrical and Chemical Synapses
A signal is transmitted from a sending neuron to a receiving neuron via chemical messengers. Arrange the following events in the correct chronological order to describe this process.
A signal is being transmitted from one neuron to another. Arrange the following events that occur at the junction between the two neurons in the correct chronological order.
