Biopsychology

?
Central Nervous System
Brain and spinal cord. Is the origin of all complex commands and decisions
1 of 26
Peripheral Nervous System
Sends info to CNS from the outside world, transmits messages from the CNA to muscles and glands in the body
2 of 26
Somatic Nervous System
Transmits info from sensory receptors to CNS. Receives info from CNS to use muscles
3 of 26
Autonomic Nervous System
Transmits info to and from bodily organs, controls involuntary actions. Split into sympathetic and parasympathetic nervous systems
4 of 26
Sensory neurons
Carry messages from the PNS to the CNS
5 of 26
Relay neurons
Connect sensory neurons to motor neurons and other relay neurons
6 of 26
Motor neurons
Connect CNS to muscles and glands
7 of 26
Synaptic transmission
Neurons communicate with each other by sending chemical signals across the synaptic cleft between them
8 of 26
Neurotransmitters
Brain chemicals released by synaptic vesicles that relay signals across the synapse from one neuron to another
9 of 26
Excitation
When a neurotransmitter increases the positive charge of the post-synaptic neuron, making it more likely for the electrical impulse to pass on
10 of 26
Inhibition
When the charge of the post-synaptic neuron becomes more negative, the electrical impulse is less likely to pass on
11 of 26
Motor area
Part of the frontal lobe involved in regulating movement
12 of 26
Somatosensory area
Area of parietal lobe that processes info from the senses
13 of 26
Visual area
Part of the occipital lobe that receives and processes visual info
14 of 26
Broca's area
Frontal lobe in left hemisphere, responsible for speech production
15 of 26
Wernicke's area
Part of the temporal lobe in the left hemisphere responsible for speech comprehension
16 of 26
Plasticity
Brain's tendency to change and adapt due to experiences and learning
17 of 26
Functional recovery
Following trauma the brain is able to relocate functions to undamaged areas
18 of 26
fMRI scans
Detects blood flow in the brain to see most active areas
19 of 26
EEG
Measures electrical impulses in the brain, can be used to diagnose things like epilepsy
20 of 26
ERP
Statistical analysis of EEG results
21 of 26
Circadian rhythm
Rhythm that lasts about a day e.g. sleep wake cycle and body temp cycle
22 of 26
Infradian rhythm
Less than one cycle in 24 hours e.g. menstruation
23 of 26
Ultradian rhythm
More than one cycle in 24 hours e.g. sleep stages
24 of 26
Endogenous pacemakers
Internal body clocks e.g. SCN's affect on sleep/wake cycle
25 of 26
Exogenous zeitgebers
External cues that affect biological rhythms e.g. sunlight
