Exam 3: Biological Foundations of Behaviour

The effects of a psychoactive drug are determined not by which chemical transmitter the drug targets, but by the drug's actions at the synapse.

After neurotransmitters are expelled into the synaptic gap, they migrate across to the postsynaptic membrane. After locking into receptor sites, any additional neurotransmitters are taken into the presynaptic membrane by a process called _______.

Wendy is watching a film while you record the electrical activity in her brain. You note that Wendy reports feeling some emotion and that there is greater activity in the left hemisphere as compared to the right. Most likely, Wendy is experiencing

The function of the descending reticular formation is to

In addition to reuptake, neurotransmitters can also be deactivated by being

If a particular drug blocked the sodium channels on an axon, the neuron

Research by Daniel Levitin on the neuroscience of music has found that tempo and rhythm tend to be processed by which areas of the brain?

To measure brain-behaviour relations, this method uses highly concentrated X-rays to take pictures of narrow slices of the brain. This method is called _______________.

Computerized axial tomography (CAT) scans, positron emission tomography (PET) scans, and magnetic resonance imaging (MRI) are all examples of which method of measuring brain-behaviour relations?

Ashley's parents do not like the contemporary techno music that Ashley and her friends listen to and prefer old show tunes to which they can sing along. Along with the neurons that help them sense the music, there is a link between the sensory input from a song they are listening to, and their memory of that song. This link is made by ___________________.

When a neuron is stimulated, tiny protein structures on the cell membrane are activated that pump specific ions back and forth, thus changing the overall potential of the neuron. These cell membranes are called _______________.

After Joe fell and hit the back of his head, his movements have been fairly uncoordinated and he has not been able to acquire any new skills that require automatic movement. Joe most likely had damage to his ____________.

Caffeine is a stimulant drug that increases the activity of neurons and other cells by ___________.
