What’s reception?

A

the stimulation of sensory receptor cells by energy (sound, light, heat, etc)

64
Q

What’s transduction?

A

transforming this cell stimulation into neural impulses

65
Q

What’s transmission?

A

delivering this neural information to the brain to be processed

66

78
Q

What’s the Trichromatic theory

A

Relative activity levels between the three different cone types are compared in the brain. This determines the colour of a stimulus. This helps to explain certain types of colour blindness.

79
Q

What is the opponent process theory?

A

Within one colour pair, one member will respond positively to one colour (e.g. blue) and negative to the other (e.g. yellow). This helps to explain complementary colour afterimages and prominence of yellow as a primary colour.

80
Q

What does the outer ear do?

A

collects sound and funnels it to the eardrum.

81
Q

What does the middle ear do?

A

the sound waves hit the eardrum and move the hammer, anvil, and stirrup in ways that amplify the vibrations. The stirrup then sends these vibrations to the oval window of the cochlea.

82
Q

What does the inner ear do?

A

waves of fluid move from the oval window over the cochlea’s “hair” receptor cells. These cells send signals through the auditory nerves to the temporal lobe of the brain.

83
Q

100
Q

A

Our brains controls all our behaviours except for simple reflexes

101
Q

What are the 2 types of major cells in the nervous system?

A

Neurons and glial cells

102
Q

What are neurons?

A

cells that receive, integrate and transmit information (i.e., permit communication). Features: soma (with nucleus), dendrites, axon, and myelin sheath, terminal branches.

103
Q

What are glial cells?

A

cells that support neurons (i.e., support communication). They provide nourishment to neurons, remove waste products, provide insulation around axons.

104
Q

How do neurons communicate?

A

transmit signals electrochemically
Each neuron receives excitatory and inhibitory signals from many other neurons.
When the excitatory signals minus the inhibitory signals exceed a minimum intensity (i.e., threshold) the neuron fires
This is called an action potential.

105
Q

What are the properties of action potential

A

A strong external stimulus can trigger more neurons to fire, and to fire more often, but it does not affect the action potentials strength or speed.
Intensity of an action potential remains the same throughout the length of the axon.

106
Q

What’s the synapse?

A

The junction between the terminal button (on the end of an axon) of one neuron (pre-synaptic), and either:
the dendrite of another neuron (post-synaptic),
the membrane of a muscle fibre, or
a gland

107
Q

What’s the synapse cleft?

A

The gap between the terminal button of the pre-synaptic neuron and the cell membrane of the post-synaptic neuron.

108
Q

What’s reuptake?

A

After the action potential is communicated to the post-synaptic neuron, the neurotransmitter that remains in the synaptic cleft is broken down by an enzyme, it is then re-absorbed by the pre-synaptic neuron and used to produce more neurotransmitter later on – process

109
Q

What’s reuptake?

A

After the action potential is communicated to the post-synaptic neuron, the neurotransmitter that remains in the synaptic cleft is broken down by an enzyme, it is then re-absorbed by the pre-synaptic neuron and used to produce more neurotransmitter later on – process

110
Q

What are neurotransmitters?

A

Each neurotransmitter has a specific function (sometimes many functions)
Transmitters can only bind to receptors where they ‘fit’ (lock and key)
Some transmitters stimulate or ‘excite’ neurons to fire, others inhibit neurons from firing
Neurons must integrate all excitatory and inhibitory transmitter inputs to come to a decision about launching or not launching an action potential

111
Q

What’s acetylecholine?

A

Usually stimulates (i.e., ‘excites’) the firing of neurons
Involved in voluntary muscle activity (e.g., walking, talking, etc.) and regulating attentiveness, arousal and memory

112
Q

What’s dopamine?

A

Mainly inhibits neuronal firing
Helps to control voluntary movement
Contributes to the experience of pleasurable emotions
Affects sleep, mood, attention, and learning

113
Q

What’s dopamine hypothesis?

A

Overactivity in dopamine circuits are associated with schizophrenia

114
Q

What are endorphins?

A

Natural opiates (or pain killers) that mainly stimulate the firing of neurons
Internally produced chemicals
Shield the body from pain and elevate feelings of pleasure

115
Q

What’s the CNS?

A

Comprised of the brain and spinal cord
Spinal cord connects the brain to the rest of the body through the peripheral nervous system

116
Q

What’s the PNS?

A

Comprised of the nerves that lie outside the brain and spinal cord
The PNS can be divided into two subareas:
Somatic nervous system: Nerves that connect to voluntary skeletal muscles and sensory receptors
Autonomic nervous system: Nerves that connect to the heart, blood vessels, smooth muscles and glands

117
Q

What’s the autonomic nervous system?

A

Refers to the ‘involuntary’ part of the peripheral nervous system (i.e., organs that we cannot control directly)
Participates in the regulation of the internal environment/organs
Heart rate, blood pressure, perspiration

118
Q

Explain and name the 2 subdivisions of the autonomic nervous system?

A

Sympathetic: Stimulates energy resources to deal with threatening situations (activates functions that accompany arousal & energy expenditure)
Ex: Fight or flight response
Parasympathetic: Acts to conserve energy (activates functions that occur during a relaxed state)

119
Q

Explain the oldest part of the brain

A

The brainstem is the oldest part of the brain, beginning where the spinal cord swells and enters the skull. It is responsible for automatic survival functions.

120
Q

What is the base of the brainstem and what does it do?

A

The medulla is the base of the brainstem that controls heartbeat , breathing, and regulates reflexes.

121
Q

What does the thalamus do?

A

122
Q

What’s the reticular formation?

A

a nerve network in the brainstem that plays an important role in controlling arousal.

123
Q

What’s the cerebellum?

A

The “little brain” attached to the rear of the brainstem. It helps coordinate voluntary movements and balance.

124
Q

What happens when damage to the cerebellum occurs?

A

Damage to the cerebellum causes coordination difficulties

125
Q

What’s the limbic system?

A

a doughnut-shaped system of neural structures at the border of the brainstem and cerebrum, associated with emotions and drives

126
Q

Amygdala is a part of the limbic system, what does it consist of?

A

The amygdala consists of two lima bean-sized neural clusters linked to the emotions of fear and anger.

127
Q

The hippocampus is a part of the limbic system, what does it do?

A

The hippocampus processes conscious memories.
It has strong connections to the amygdala, with emotionally significant events being more likely to be encoded.

128
