Exam 3: Biological Foundations of Behaviour

During the chemical communication process, neurotransmitters cross the synapse and attach themselves to receptor sites on the postsynaptic neurons. This stage is called ________________.

A nerve cell has a mitochondria and endoplasmic reticulum?

The outermost layer of the brain and the crowning achievement of brain evolution is called the __________.

The two divisions of the sympathetic nervous system are the somatic nervous system and the autonomic nervous system.

Brain functions, including memory, planning, and attention, can be measured using ___________, which assesses verbal and non-verbal behaviours to provide clinical evaluations of individuals.

Research by Shamay-Tsoory and colleagues on criminals with antisocial personality disorder may have deficits in what area?

Harry is going to Mei's house to feed Mei's cat while she is gone. Mei left Harry her key ring, but when Harry reaches the front door, he realizes he doesn't know which key fits the lock. He tries several before finding the right one. If we compare the key and the lock to the behaviour of communicating neurons, we can say that the key is like a __________________ and the lock is like a ________________________.

In the human body, the sympathetic system is responsible for activating the body for such things as the fight-or-flight response. The system is responsible for calming and slowing down the body is called the ____________________.

An oversupply of dopamine, a neurotransmitter that can be excitatory or inhibitory, has been implicated in schizophrenia, and an undersupply of dopamine has been implicated in depression.

The function of the axon is to

Let's say that you are working on a new drug treatment for depression. According to your text, which of the following neurotransmitters are you likely to target?

You don't want your pet turtle Flash to be bored, so you go out of your way to make his cage very exciting and interesting. You change things around frequently and give him new things to explore. If your efforts actually produced changes in the neurons of Flash's brain, then they would best illustrate the concept of _____________.

The reticular formation does NOT play a major role in

The fact that young children typically have about 50 percent more synapses than adults do may best explain why

Research has demonstrated that rat pups raised in stimulating environments had larger neurons with more dendritic branches. Similarly, musicians who do complex string work with their left hands tend to have larger corresponding somato sensory areas. These are both examples of

What are the three major types of neurons in the nervous system?

In a large communication network such as the National Telephone Company, the actual cables and transmissions could be analogous to the body's neurons, while the technicians and mechanics that support the equipment are analogous to the body's __________.

The main function of glial cells is to speed up the transmission of neural impulses.

If released, an inhibitory neurotransmitter would induce a state of depolarization?

At a local university the freshman hazing involved chugging bottles of vodka. When two naïve young men fell unconscious after finishing the bottles of vodka, their girlfriends rushed them to the emergency room. It seems their basic body functions had been suppressed by the alcohol and they died from heart failure. Which portion of the brain governs these vital body functions?
