Exam 3: Biological Foundations of Behaviour

Describe the two divisions of the autonomic nervous system as well as their roles in maintaining homeostasis.

Alcohol effect on the brain is as a(n)

The job of the sensory neurons is to transmit neural impulses from the sense organs to the brain.

When Leslie was born, the doctor delivering her used forceps incorrectly. As a result, Leslie suffered a basal skull fracture and spent the first two weeks of her life in intensive care. Doctors told Leslie's parents that she would experience full recovery but that same fracture is often fatal in twenty year olds. The most likely reason for Leslie's recovery is that

What chemical changes cause the process of depolarization that creates graded and action potentials? How do these potentials differ from one another?

The primary job of the ascending reticular formation is to

in order to get information about brain function, which of he following scans should you use?

When the charge inside of a neuron shifts from -70 millivolts to + 40 millivolts, it is called

When the potential of a neuron is made more negative (e.g., moved from -70 to -73 millivolts), the neuron has experienced a depolarization.

The sympathetic and parasympathetic nervous systems play complementary roles in maintaining a balanced and constant internal state called __________.

Which structural characteristics permit the many possible interconnections among neurons?

Research on emotion has found that positive emotions such as happiness tend to be located in the left hemisphere, while negative emotions such as anger and sadness are more associated with activity in the ___________.

The alternate opening and closing of sodium and potassium channels in the axon is responsible for generating

An agonist can produce its effects by each of these EXCEPT ___________.

Which technique produces the most detailed, coloured images of the brain and can be used to study both brain structure and brain activity?

The main purpose of spinal reflexes is to ___________.

The synaptic cleft is a ___________.

A family member has started to show problems controlling his impulsive behaviour and his judgment is questionable. You suspect the onset of dementia, with brain damage in the

Rita has always wanted to learn to play the piano. At 40, she decides to take piano lessons. She picks the skill up quickly, partly, her teacher says, because she's so eager to learn. As she learns, the neurons in Rita's brain are changing to store the new information and habits; this is referred to as

People who have paralysis due to a break in the spinal cord have intact sensory neurons in spite of their inability to experience sensation in the paralyzed areas. The problem is that the sensory information cannot reach the part of the brain that translates it into actual sensation. This part of the brain is called
