Areas rich in fat-sheathed neural axons that form the connections between the brain cells are considered:
grey matter
white matter
fat matter
axonized areas
The brainstem mediates:
regulatory functions
sensory information
cognitive functions
Which fibers carry information from the spinal cord to the muscles?
efferent fibers
transporter fibers
afferent fibers
corpus callosum
Associative learning is mainly associated with:
pons
pre-frontal cortex
cerebellum
basal ganglia
The amygdala is a structure mainly associated with:
personal memory
social interactions
emotion
spatial navigation
Areas that receive sensory input are named:
association areas
primary areas
the best areas
secondary areas
Neurons in the neocortex are arranged in:
twelve layers
six layers
random ways
two main layers
Given that layer 4 constitutes an input zone of sensory analysis and layer 5 an output zone, which cortex has a larger layer 4 and smaller layer 5?
somatosensory cortex
motor cortex
prefrontal cortex
both somatosensory and motor cortices
Where does an action potential begin?
axon hillock
dendrite
axon collateral
soma
Synapses that decrease neurons' ability to pass info along to other neurons are called:
unsettled synapses
synapses never decrease neurons' ability to pass info along to other neurons
excitatory synapses
inhibitory synapses
What happens on the postsynaptic membrane?
the neurotransmitter binds to receptor proteins
the mitochondrion is formed
nothing really happens
the neurotransmitter is released into the synaptic cleft
Positive symptoms in psychosis have been associated with increased:
serotonin
dopamine
noradrenaline
in psychosis neurotransmitters are decreased, not increased
