The band of myelinated nerve fibres that connects the right and left brain hemispheres is called the

Which of the following is NOT a function of glial cells?

What are the four lobes of the brain and where are they located?

In order to speak properly, there are at least two areas of the brain that need to be functioning. If you could move your tongue and lips but not sequence the words properly, the damage would be most likely in

When it's time to release a neurotransmitter from a synaptic cleft, the neurotransmitter

The left and right hemispheres of the brain are connected by a broad white band of myelinated nerve fibres called ____________.

The presence of many branches on the axons makes it possible for a single neuron to connect to the dendrites of as many as 50,000 other neurons. The branches on the axons are called ______________.

You are looking at the electrical activity at a receptor site on the postsynaptic membrane. The measured potential is -80 millivolts (below the resting potential). How is this possible?

An inhibitory neurotransmitter really works by

James was in an accident where he received damage to Wernicke's area. Which lobe of the brain did the damage occur to, and what type of difficulty would you predict James having as a result? How would your prediction change if he had received damage to Broca's area?

If the nervous system is like a car, then the sympathetic nervous system and the parasympathetic nervous system would be most like the ___________.

Split-brain research was made possible originally by surgical techniques done to limit the potential brain damage caused by epileptic seizures. This was accomplished by cutting the _________________.

Let's say that you are a crime scene investigator. A victim has died and all you know is that the likely cause from a neurotransmitter level was due to GABA. What else would you suspect about this death?

Jon hears his phone ring and reaches out his hand to answer it. Which type of neurons did Jon use to input the sound of the phone?

Why do children typically show better recovery of function after brain injury?

We are comparing two individuals, individual 1 is resting at home after having dinner. Individual 2 is in the jungle running away from a wild animal. Which nervous systems are activated in individuals 1 and 2?

Differentiate between the central nervous system and the peripheral nervous system. What are the two divisions of the peripheral nervous system?

Which of the following would best be viewed as a description of the association cortex?

Research on the brains of people with schizophrenia suggests problems with the structure that organizes sensory information and routes it to appropriate parts of the brain; that is, the ________________. This malfunctioning structure may therefore be responsible for schizophrenic hallucinations and other disturbing sensory experiences.

The synaptic cleft is a tiny gap between
