Level 1
The physical distance from one energy cycle to the next; changes in ___________________ are often perceived as changes in color.
wavelength
Also known as the eardrum, this structure transfers energy to the three smallest bones of the body known as the ossicles.
tympanic membrane
Receptors in the skin specifically designed to detect changes in temperature.
thermoreceptors
A visual depiction of what our bodies would look like if they were built in proportion to their representation on the cortex.
sensory homunculus
When the freedom of 'choice' to participate in research is compromised as a result of undue influence from another source.
situational vulnerability
The location in the occipital lobe where visual information is organized and analyzed.
visual striate cortex
A theory of color vision that proposes that color information is identified by comparing the activation of different cones in the retina.
trichromatic theory
The location of taste-sensitive cells on the tongue.
taste pore
Diseases in which parts of the brain slowly die over time, resulting in greater disability as the disease progresses.
neurodegenerative diseases
A term referring to a 'do-over' of a study using the same methods, but different subjects and investigators.
replication
Also known as our sense of balance.
vestibular sense
The process by which external sensations are converted into neural firing in the brain.
transduction
The spatial organization of touch; two adjacent points on your skin are represented by adjacent points on the somatosensory cortex.
somatotopic organization
Consisting of clustered groups of neurons called the caudate and putamen, part of the basal ganglia closer to the neocortex that play a central role in coordinating movement.
dorsal striatum
A committee of independent people who review and assess whether a research project will be carried out in a way that is consistent with general ethical principles.
Institutional Review Board (IRB)
The structures in the inner ear that respond to cues associated with balance and posture.
vestibular sacs
The integration of a person's beliefs, memories, and expectations into their sensory experiences to create a perception.
top-down processing
The location in the parietal lobe where touch and motion are processed.
somatosensory cortex
A bias whereby only a motivated fraction of a population respond to a survey or participate in research.
volunteer bias
A part of the cerebral cortex known to play a role in the transference of certain types of memories into long-term memory stores.
hippocampus
Also known as the What stream, this pathway takes information from the occipital lobe to the temporal lobe where we are able to identify an object.
ventral stream
The spatial organization of the basilar membrane is maintained through the auditory pathway.
tonotopic organization
The structures in the inner ear that sense changes in acceleration and the rotation of the head.
semicircular canals
Participants respond to questions in ways that would be seen as acceptable by others.
socially desirable bias
The ethical principle of developing trusting relationships between researchers and participants.
fidelity
