The brain contains billions and billions of neurons. These cells
communicate with one another by releasing small endogenous chemical
messengers, called neurotransmitters, into the synapse, where they are then taken

The Role of Electricity in Neural Acvitity
Genes and the
Genes are hereditary information made
up of molecules called DNA
Some genes achieve their effects by the
production of proteins.
Genes can turn their expression or
activity on, off, up, or down.
Genes effect the level of
1. Does the membrane time constant of a neuron change during an action potential?
Yes the time constant is dependent on membrane resistance and
capacitance. While the capacitance stays constant, the membrane resistance
changes due to opening/closing

1. Name and describe 3 substances utilized in the pharmaceutical industry that affect
transmission at GABAergic synapses.
a. Barbiturates (pentobarbital) increase the duration of the open state of
the GABAAR channel.
b. Benzodiazepines (Valium) increase t
