Exam 3: Neurons and Synapses

Which neurotransmitter is likely responsible for the pleasurable feelings that come from taking drugs like cocaine?

Psychoactive drugs affect the brain's _______.

Neurons that have direct outputs to muscles or glands are _______ neurons.

The large cell whose main function is to wrap a layer of "insulation" around axons is called the:

Beyond rate coding, neurons may communicate using:

Neurotransmitters are sometimes broken apart by other molecules. This process is called:

The term for a neurotransmitter moving out of the synapse is:

Chemical signals are collected, converted into an electrical signal, then integrated. A new electrical signal is generated. What is the next step?

Neurons can be classified by their shape. Which term is used for neurons that have a single dendrite on one end and a single axon on the other?

Neurons found in your skin are efferent nerves.

Sometimes after binding to a receptor, neurotransmitters will be pulled back inside a neuron. This is called:

Any given neuron in your brain is connected to five or fewer other neurons.

Neurons code information with single spikes.

One way to classify the complexity of a brain is to compare the proportion of sensory and motor neurons to:

Saltatory conduction describes the smooth movement of action potentials within a neuron.

Neurons are very noisy-whether or not they are currently firing is probabilistic.

All of the following are problems with local coding except:

Thanks to the help of microscopy, we now know that the brain is made up of:

Serotonin and melatonin are classified as:

If the inside of a neuron is flooded with positively charged sodium ions, there would be a/an:
