Which behavioural functions are controlled by the hindbrain structures, namely, the medulla, the pons, and the cerebellum? What occurs with damage to these structures?

A primary advantage of spinal reflexes appears to be that the reaction times are reduced because the ________________.

Which of the following neurotransmitters have NOT been associated with depression?

Rafiel was at a party and drank a lot of alcohol. He had trouble walking in a straight line. Most likely, this is because the alcohol affected his

You are looking at a chemical substance in the brain. You know that it is involved in synaptic transmission, but it does not seem to have any direct excitatory or inhibitory effect. Rather, it seems to intensify the effect of other neurotransmitters. Most likely, you are looking at

A neuron is responsible for conveying a message from the brain to a particular muscle, such as the muscle that contracts your eyelid. This neuron would be classified as a(n)

When someone faces a situation that makes him feel both terrified and helpless, he may develop Post Traumatic Stress Disorder (PTSD). Later, things in the environment that are reminiscent of the trauma may trigger the same fear and aggression he experienced during the trauma. The part of the brain that is responsible for organizing and remembering emotional events is the

Helina fell off her bike and hit her head hard. When she woke up in hospital, she was not able to see. Most likely, this was from the pressure on the

The only sense that does not send information through the thalamus is the sense of ___________.

Carol suffers from multiple sclerosis. According to your textbook, this is an issue of a disruption in the timing of nerve impulses due to

The brain's sensory switchboard is ___________________.

You are observing the speed of an action potential in a neuron. You note that the conduction speed is quite high (300 kilometres an hour). Most likely, this neuron

The area responsible for speech production is called

How do neurotransmitters achieve the processes of excitation and inhibition of postsynaptic neurons?

The drug Naloxone can be used to reverse opioid overdoses. It works by preventing the binding of opioids to their receptors. Naloxone must therefore be

Drugs such as cocaine, amphetamines, nicotine, and alcohol all stimulate the release of dopamine in the ______ of the limbic system.

Both the cerebellum and the basal ganglia are involved in the control of movement. However, they have very different roles. The basal ganglia is responsible for ___________ movement whereas the cerebellum is involved in ___________ movement.

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