nervous system
what are the 3 main categories of the nervous system
central, peripheral, enteric
the gaps between the myelin sheath are called what
nodes of ranvier
sensations are translated to electrochemical transmission
obtaining information from external stimuli in the environment
using previous knowledge to interpret that sense information
which is sensation, perception, and transduction
1transduction
2sensation
3perception
what are the 5 taste categories
sweet, salty, sour, bitter, savory (umami)
do antagonists or agonists make a drug more effective
agonists
true or false: the somatic and autonomic nervous systems are subcategories of the central nervous system
false- what part of the nervous system are they a part of?
what are oligodendrocytes and schwann cells
oligodendrocytes- myelin sheath in the PNS
schwann cells- myelin sheath in CNS
the opponent process of color vision would suggest that after staring at red thing for a while you will see what color afterimage
green
how does using both ears help us get more information about the sound we are hearing
level- you will know where the sound is coming from because it will be louder in the ear it is closer to
you touch a hot stove and reflexively pull your hand back, what part of your nervous system is at work
peripheral more specifically autonomic
which system controls involuntary movement, what is an example of involuntary movement
autonomic; heart beat, breathing, reflexes
signals between neurons are [electrical/chemical] and signals within neurons are [electrical/chemical]
between- chemical
within- electrical
what are each called?
integrating information from the outside world into previous beliefs is top down or bottom up processing
top down
the process of tasting something is called [insert] and it involves chemicals binding to the taste sensitive cells
how many taste sensitive cells are in each taste bud?
transduction
50-100
what is the part of the brain that connects the left and right hemisphere called
corpus callosum
the [afferent/efferent] pathway will take information from your senses and send it to the brain
afferent
what are the 4 main lobes of the brain and one function of each
frontal lobe-when, why, how, contains motor cortex which controls voluntary movement
parietal lobe- organization, integration, calculations
occipital lobe- vision
temporal lobe- formation and retrieval of new memories, hearing and smell info
what are monocular vs binocular cues and give an example of each
monocular- only need one eye to detect; occlusion, relative height, relative size, perspective convergence
binocular- need both eyes to detect; retinal disparity, convergence
higher pitched sounds will excite cells in the cochlea that are closer to the [oval window/basilar membrane]
oval window
true or false: if you get a cut on your left hand, your nociceptors in your peripheral nervous system will send information through afferent neurons to your right somatosensory cortex which is located in the parietal lobe
True
what are the two hormones produced by the enteric system
dopamine and serotonin
what is the difference between brain perturbation and brain imaging? name one technique for each
brain imaging- observing brain activity without manipulating activity; EEG, PET, MRI, fMRI, FNIRS
The ventral stream refers to the path that goes from the occipital cortex through [insert] cortex
The dorsal stream refers to the visual path in the [insert] cortex
temporal, parietal
ventral: occipital to temporal
dorsal: occipital to parietal
tip to remember DOP? dorsal fin to see WHERE shark is going- dorsal=location
a light with a high frequency (longer wavelength) and a higher amplitude will have a more [red/purple] hue and be [brighter/duller]
red and bright
rods detect [detail/movement] and are active in [bright/low] light
cones detect [detail/movement] and are active in [bright/low] light
rods- movement and low light
cones- detail and bright light
