Flashcards in Role of biology in psychology Deck (18)
What does EEG measure?
The electrical activity of neurons
What does the functional magnetic resonance imaging (fMRI) track?
oxygen level in the blood
What causes transcranial magnetic stimulations
a temporary disruption of the activity in carefully targeted parts of the brain
What takes more space in the somatosensory cortex?
more sensitive area. (not larger area)
What lobe process touch and pressure
The parietal lobes
Name the main neurotransmitters and their function
Dopamine -> motor control over voluntary movements, reward and motivation
Acetylcholine -> Motor control over muscles, attention, memory, learning sleeping
Serotonin->Emotional states and impulse control, dreaming
GABA->inhibition of action potential, anxiety reduction
Glutamate-> enhancement of action potential, learning and memory
Endorphins-> Pain reduction/reward.
What does contain the Occipital lobes?
the primary visual cortex (visual info) AND secondary visual area, which process the specific feature of the visual input
What does the autonomic nervous system regulate?
body glands and internal organs (like the heart)
What is the role of the somatic division of the peripheral nervous system?
Sending and receiving signals from the skin, muscles, and joints.
What is the difference between the central nervous system and the peripheral nervous system?
The CNS encompasses the brain and spinal cord
The PNS encompasses every body part other than the brain and spinal cord.
what happens when a neuron fire?
1. An action potential occurs
2. chemicals are released from the terminal buttons
3. The electrical charge of the neuron becomes more positive inside
What is the function of the Hypothalamus
regulates thirst and need to replenish fluids
What is the function of cerebellum
plan and coordinate movements, motor learning, motor memory
What brain structure is the sensory relay station for the brain
What gland govern bodily rhythms
When a near is in a resting state, the electric charge inside the neuron is slightly more ____ than the charge outside. When the neuron is stimulated, _____ ions carrying_____ charge enter, until an action potential is triggered. At this point, _____ ions leave the neuron, but within milliseconds the sodium potassium______reverses the flow of both kinds of ion, until the original balance is restored
Negative; sodium; positive, potassium; pump
The basal ganglia is important in
planning and producing movement
