This type of photoreceptor fires most actively when the stimulus is either green, blue, or red. It's also most responsible for high resolution vision of stimuli that are directly in front of the eye.
What is cones?
100
Also referred to as the tympanum, this part of the ear receives sound waves, passing on their vibration to hammer, anvil, and stirrup bones in the middle ear.
What is the eardrum?
100
Nasal cavity is lined with these bad boys that can differentiate between around 20,000 different odor molectues
What are the olfactory receptors?
100
Free nerve endings located at the edge of epidermis allow for us to feel this sensation.
What is light touch?
100
Receptors in your muscles, tendons, and skin allow you to feel the space you inhabit.
What is kinesthetic sense?
200
This part of the eye contains three layers of cells, each one connecting to the next via junctions between neurons, through which information can pass. Only the third layer, at the very back of the retina, bears light-sensitive cells - the rods and the cones.
What is the retina?
200
This part of the ear contains three fluid-filled ducts. Here we can find the organ of Corti, lined with hair cell receptors that transform vibrations into action potentials.
What is the cochlea?
200
This orb is found in the limbic system, close to the amygdala and hippocampus, explaining why we experience Madeleine effect when encountering familiar smells.
What is olfactory bulb?
200
When you feel a vibration on your skin (or in your back pocket), these receptors found in your outer and inner deepest layers of skin send electrical signals to the somatosensory cortex.
What is Pacinian and Meissner's corpuscles?
200
Hair cells in the semicircular canals track rotation of the head relative to the ground.
What is vestibular sense?
300
This part of the eye is more densely packed with cones and is located right in the center of the retina, forming a pit. The cones here have a direct signal-sending pathway to the brain, thus creating the most detailed visual signals.
What is the fovea?
300
This part of the brain sits on the brain stem and processes information about direction of sound
What is the superior olive?
300
This chemical is detected by the olfactory bulb without our conscious awareness
What is pheromone?
300
This part of the brain is mapped in the shape of a homunculus (=little man).
What is the somatosensory cortex?
300
In some cases of amputated limbs, the person continues to experience pain or sensation.
What is phantom limb syndrome?
400
This ability allows us to see the world in 3D. The distance between the eyes dictates the angle of the viewed object or a scene. The brain calculates the difference between incoming images to produce three dimensional representation.
What is depth perception?
400
This part of the brain is found beneath the thalamus in the midbrain and is responsible for integrating sound information with other sensory inputs.
What is inferior colliculus?
400
This flavor is the newest addition to the basic flavors menagerie, thought to signal presence of protein. Also means "delicious" in Japanese.
What is umami?
400
These receptors are dedicated to processing of painful stimuli.
What is nociceptors?
400
This treatment is offered to patients with phantom limb syndrome, allowing them to use mirrors in order to touch or massage the missing limb.
What is mirror treatment?
500
Light triggers photoreceptors to fire in the eye, sending signals down the optic nerve to optic chiasm, to the thalamus, and from there the message is sent to the occipital lobe for elaborate processing.
What is the visual pathway?
500
Found in the temporal lobe, this part of the brain is mapped according to the frequency of sound, matching frequency map of sensory cells in the cochlea.
What is the auditory cortex?
500
These little guys found on your tongue are composed of about 25 receptor cells, layered like a bunch of bananas! They interact with taste molecules, sending that information to the medulla, thalamus and finally to the taste area in the somatosensory cortex.
What is a taste bud?
500
This pathway relays information from the body up through the brainstem to the thalamus, then to the somatosensory cortex area, and then to the cingulate cortex that processes the emotional significance of the sensation.
What is the pain pathway?
500
This is our sixth sense (not the one in the movie) that combines the kinesthetic and vestibular senses.
