Exam 3: A: The Biological Bases of Behaviour

Choose a specific neurotransmitter or class of neurotransmitters and discuss its impact on behaviour.

A neuron just sent a neural impulse.It will be one to two milliseconds before another neural impulse can be generated.What do we call this brief time increment,when another neural impulse cannot occur

Four sisters were all raised in the same household by parents who are very creative and artistic.Anna and Betty are the biological children of their parents,while Cassie and Deanna were adopted as infants into the family.Like their parents,Anna and Betty are artistically inclined and enjoy working on creative projects.Cassie and Deanna are not particularly interested in artistic endeavours even though they've received a lot of exposure to art and a lot of encouragement for creative work.Which conclusion would be reasonable if this pattern occurred in a variety of similar families

Dr.Smith destroys a small piece of tissue in the forebrain of a rat to determine whether that area is important for maze-learning.What is this technique called

Standing outside a football stadium and judging the excitement of the game by the crowd's screams is analogous to "eavesdropping" on the brain using which of the following

What are the two most basic divisions of the nervous system

What seems to be a primary cause of Parkinson's disease

If a trait is described as polygenic,what does that mean

Hormones tend to be released in a pulsatile pattern.What does this mean

If our planet were a place where each individual has the opportunity to acquire all necessary resources,and each individual produces exactly one offspring in his or her lifetime,what impact would this have on the process of evolution by natural selection

By altering brain structures,an evil scientist has created supervillains who have specialized powers or abilities.One of these supervillains has a fantastic memory and can form new memories incredibly well.In this case,which brain structure was likely altered

Bradley is deeply relaxed and many of his muscles are not moving at all.What does this suggest about many of Bradley's motor neurons

Imagine that a picture of a blue circle is briefly flashed in the left visual field of an individual with a severed corpus callosum.At the same time,a picture of a red square is briefly flashed in the right visual field.What would this individual likely say,based on Roger Sperry's work with split-brain patients

Much of what we know about left brain/right brain differences would not be known without systematic research and analysis.The current interest in the right brain/left brain phenomenon highlights the importance of approaching topics such as this from which point of view

If a monkey's mirror neurons fire when the monkey picks up a grape,when will those same neurons also fire

What is the correct sequence of structures through which information flows in a neuron

What do we call the process of absorption of neurotransmitters into the presynaptic neuron

Humans' taste preferences for fatty substances would have conferred a survival advantage for our ancestors,but in our modern environment,where we have an overabundance of food,that preference can end up causing obesity and illness.What would an evolutionary psychologist say about this trend

Which technique results in effects that are similar to that of lesioning

Which cells in the nervous system do most of the work of receiving,integrating,and transmitting information
