Question 1 of 9

1

Acetyl Choline always produces an EPSP.

Select one of the following:

  • True
  • False

Explanation

Question 2 of 9

1

Glutamate produces an IPSP.

Select one of the following:

  • True
  • False

Explanation

Question 3 of 9

1

Gaba produces an IPSP.

Select one of the following:

  • True
  • False

Explanation

Question 4 of 9

1

Choose the correct statements about methamphetamine.

Select one or more of the following:

  • It increases levels of noradrenaline, dopamine, and serotonin.

  • It blocks the reuptake of noradrenaline, dopamine, and serotonin.

  • It acts in reward centres and as such is highly addictive.

  • It stimulates the parasympathetic nervous system.

Explanation

Question 5 of 9

1

Choose the incorrect statement.

Select one of the following:

  • Acetylcholine activates stimulus gated Na+ channels, and can be found in NMJs and the brain.

  • Glutamate activates stimulus gated Na+ and Ca+ channels, and is the most common excitatory neurotransmitter in the CNS.

  • GABA activates Na+ and Cl- channels, and is the most common inhibitory neurotransmitter in the CNS.

Explanation

Question 6 of 9

1

A neuron can have >50,000 synapses at its input zone.

Select one of the following:

  • True
  • False

Explanation

Question 7 of 9

1

Local synaptic potential (EPSPs and IPSPs) summate.
Spatial summation is integration of inputs from . (Different localisation/ of input zone.)
Temporal summation is the integration of inputs from the but from different, .

Drag and drop to complete the text.

    different synaptic knobs
    local polarisations
    same synaptic knob
    short time intervals

Explanation

Question 8 of 9

1

Local polarisations last longer than action potentials. This allows temporal summation to be effective.

Select one of the following:

  • True
  • False

Explanation

Question 9 of 9

1

Converging networks can amplify signals. They have few control points and can therefore allow precise control.
Diverging networks provide redundancy, making sure there is a 'back up' should another transmission fail and assuring an action is carried out.

Select one of the following:

  • True
  • False
