Autonomic Nervous System (ANS)
Governs the brain's involuntary actions (such as heartbeat, stress, etc). It is divided into the sympathetic branch and parasympathetic branch.
1 of 37
Brain
It is responsible for coordinating sensation, intellectual and nervous activity.
2 of 37
Central Nervous System (CNS)
It comprises of the brain and the spinal cord and it receives information from the senses and controls the body's responses.
3 of 37
Peripheral Nervous System
The part of the nervous system that is outside of the brain and the spinal cord.
4 of 37
Somatic Nervous System
The part of the peripheral nervous system that is responsible for carrying sensory and motor information to and from the CNS.
5 of 37
Spinal Cord
A bundle of nerve fibres within the spinal column that connect to nearly all parts of the body and brain.
6 of 37
Motor Neurons
They form synapses with muscles and control their contractions.
7 of 37
Neurotransmitter
Chemical substances that transmit nerve impulses across a synapse.
8 of 37
Relay Neurons
They are the most common type of neuron in the CNS. They allow sensory and motor neurons to communicate with each other.
9 of 37
Sensory Neurons
They carry neurons from sensory receptors to the spinal cord and the brain.
10 of 37
Synapse
The conjunction of the end of the axon of a neuron and the dendrite or cell body of another.
11 of 37
Synaptic Transmission
This is the process of a nerve impulse passing across the synaptic cleft from one neuron (pre) to another (post).
12 of 37
Endrocrine Glands
This is a special group of glands within the endocrine system, who produce and secrete hormones.
13 of 37
Endocrine System
This is a network of glands throughout the body that manufacture and secrete hormones (chemical messengers).
14 of 37
Hormones
Chemical messengers that travel through the bloodstream influencing processes such as mood, stress response and bonding between mother and baby.
15 of 37
Pituitary Gland
The 'master gland' which influences the release of other hormones from other glands.
16 of 37
Fight or Flight Response
A sequence of activity that is triggered when the body prepares itself for defending/attacking or running away. This activity involves changes in the nervous system that are necessary to sustain arousal.
17 of 37
HPA Axis
The sequence of bodily activity in response to stress that involves the hypothalamus, pituitary and adrenal cortex.
18 of 37
Broca's Area
An area in the frontal lobe, usually in the left hemisphere that is responsible for speech production
19 of 37
Localisation of Function
The belief that specific areas of the brain have specific functions and cognitive processes.
20 of 37
Motor Cortex
A region in the brain that is responsible for the generation of voluntary motor movements.
21 of 37
Somatosensory Cortex
A region in the brain that processes input from sensory receptors in the body that are sensitive to touch.
22 of 37
Wernicke's Area
An area in the temporal lobe that is responsible for understanding language.
23 of 37
Hemispheric Lateralisation
Mental processes that are mainly specialised to either the left or right hemisphere.
24 of 37
Split-brain Research
Research that studies individuals who have had the surgical seperation of the two hemispheres of the brain as a result of severing the corpus callosum.
25 of 37
Brain Plasticity
The brain's ability to modify its own structure and function as a result of experience.
26 of 37
Functional Recovery
The ability and mental processes that have been compromised as a result of brain injuryt or disease.
27 of 37
Electroencephalogram (EEG)
A method of recording changes in the electrical activity of the brain using electrodes attached to the scalp.
28 of 37
Event-related Potential
It takes raw EEG data and uses it to investigate cognitive processing of a specific event. It takes multiple readings and averages them to filter out the brain activity that is not related to the stimulus.
29 of 37
Functional Magnetic Resonance Imaging (fMRI)
Measures brain brain activity by detecting changes in blood oxygenation and flow that indicate increased neural activity.
30 of 37
Post-mortem Examinations
Examining the brains of people who have shown particular psychological abnormalities prior to their death in an attempt to establish the possible neurobiological cause for this behaviour.
31 of 37
Circadian Rhythm
A pattern of behaviour that occurs or recurs approximately every 24 hours, and is set and reset by environmental light levels.
32 of 37
Sleep-wake Cycle
Alternating states of sleep and waking that are dependent on 24 hour circadian cycle.
33 of 37
Infradian Rhythm
Rhythms that have a duration of over 24 hours, and may be weekly, monthly or even annually.
34 of 37
Ultradian Rhythm
Cycles that last less than 24 hours, such as the cycle of sleep stages that occur throughout the night.
35 of 37
Endogenous Pacemakers
Mechanisms within the body that govern the internal, biological bodily rhythms.
36 of 37
Exogenous Zeitgeber
An environmental cue, such as light, that helps to regulate the biological clock in an organism.
