1Acetyl Choline always produces an EPSP.
- ATrue
- BFalse
2Glutamate produces an IPSP.
- ATrue
- BFalse
3Gaba produces an IPSP.
- ATrue
- BFalse
4Choose the correct statements about methamphetamine.
- AIt increases levels of noradrenaline, dopamine, and serotonin.
- BIt blocks the reuptake of noradrenaline, dopamine, and serotonin.
- CIt acts in reward centres and as such is highly addictive.
- DIt stimulates the parasympathetic nervous system.
5Choose the incorrect statement.
- AAcetylcholine activates stimulus gated Na+ channels, and can be found in NMJs and the brain.
- BGlutamate activates stimulus gated Na+ and Ca+ channels, and is the most common excitatory neurotransmitter in the CNS.
- CGABA activates Na+ and Cl- channels, and is the most common inhibitory neurotransmitter in the CNS.
6A neuron can have >50,000 synapses at its input zone.
- ATrue
- BFalse
7Local synaptic potential (EPSPs and IPSPs) summate.
Spatial summation is integration of inputs from [blank_start]different synaptic knobs[blank_end]. (Different localisation/[blank_start]local polarisations[blank_end] of input zone.)
Temporal summation is the integration of inputs from the [blank_start]same synaptic knob[blank_end] but from different, [blank_start]short time intervals[blank_end].- Adifferent synaptic knobs
- Blocal polarisations
- Csame synaptic knob
- Dshort time intervals
8Local polarisations last longer than action potentials. This allows temporal summation to be effective.
- ATrue
- BFalse
9Converging 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.- ATrue
- BFalse
