Short-term memory information processing usually causes changes in the
hippocampus
Forming new long-term memories is strikingly disrupted after damage
to the
hippocampus
When Phineas Gage had a metal rod driven into his frontal lobe he experienced
greatly altered emotional responses
An injury to the occipital lobe will likely impair the function of the
primary visual cortex
A ligand for the umami receptor in the sense of taste is
monosodium glutamate
The olfactory bulbs are located in the
brain
The correct sequence of sensory processing is
stimulus reception ? sensory transduction ? sensory perception ?
sensory adaptation
Artificial electrical stimulation of a human's capsaicin-sensitive
neurons would likely produce the sensation of
hot temperature
Artificial electrical stimulation of a human's menthol-sensitive
neurons would likely produce the sensation of
cold temperature
Tastes and smells are distinct kinds of environmental information in that
neural projections from taste receptors reach different parts of the
brain than the neural projections from olfactory receptors
Stimuli alter the activity of excitable sensory cells via
transduction
Immediately after putting on a shirt, your skin might feel itchy.
However, this perception soon fades due to
sensory adaptation
A given photon of light may trigger an action potential with
thousands of times more energy because the signal strength is
magnified by
an enzyme-catalyzed reaction
The generation of action potentials in olfactory neurons initiated by
odors drawn into the nasal cavity is an example of
sensory transduction
Umami perception would be stimulated by
a savory and rich cheese
Statocysts contain cells that are
mechanoreceptors used to detect orientation relative to gravity
An earthworm without a statocyst would not be able to
orient with respect to gravity
The cellular membrane across which ion flow varies during auditory
transduction is the
hair cell membrane
Sound waves arriving at a listener first strike the
tympanic membrane
The pathway leading to the perception of sound by mammals begins with the
hair cells of the organ of Corti, which rests on the basilar
membrane, coming in contact with the tectorial membrane.
The cochlea is an organ of auditory transduction that contains
fluid and cells that can undergo mechanosensory transduction
Dizziness is a perceived sensation that can occur when
moving fluid in the semicircular canals encounters a stationary cupula
The perceived pitch of a sound depends on
which region of the basilar membrane was set in motion
It can be very difficult to select an angle for sneaking up to a
grasshopper to catch it because grasshoppers have
compound eyes with multiple ommatidia
Sensory transduction of light/dark information in the vertebrate
retina is accomplished by
rods and cones
Rods exposed to light will
hyperpolarize due to the closing of sodium channels
A rod exposed to light will
undergo a graded hyperpolarization that will decrease its release of glutamate
In the human retina
cone cells can detect color, but rod cells cannot
In a cephalized invertebrate, the system that transmits
"efferent" impulses from the anterior ganglion to distal
segments is the
peripheral nervous system
Our understanding of mental illness has been most advanced by
discoveries involving the
chemicals involved in brain communications
Failure of an embryonic neuron to establish a synaptic connection to
another cell
results in the apoptosis of that neuron
Experiments with genetically altered mice showed that the mice would
consume abnormally high amounts of bitter-tasting compounds in water
after their
sweet-taste cells were altered to express receptors for bitter
tastants, suggesting that the sensation of taste depends only on which
taste cell is stimulated
