The Mind-Body Problem
the problem of explaining how mental states, events and processes—like beliefs, actions and thinking—are related to the physical states, events and processes, given that the human body is a physical entity and the mind is non-physical.
look at learning, learning is growing new axons
in a statistical model that correlates (directly or inversely) with both the dependent variable and the independent variable.
What are the major parts of a neuron?
Dendrites stems (retrieve info), Soma cell body (genetic info stored here), Axon (connects other nerve cells, electrical pulses)
How do action potentials work?
A difference in charge that starts inside the neuron or axon
What makes a drug an agonist or an antagonist?
Agonists mimic action of neurotransmitter and antagonists black the action of neurotransmitters
Located just above our ears on both sides of our head, the temporal lobes control our hearing and contain the auditory cortex
receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements
Located in the front of the parietal lobe (directly behind the sensory cortex in the frontal lobe), this structure is responsible for us feeling touch sensations from our body
Located in the left frontal lobe (at least for most people- in some left handed people, Broca's area is on the right side), this areas controls the muscles in our mouth involved in speech
region of the brain that contains motor neurons involved in the comprehension of speech
a small organ located within the brain's medial temporal lobe and forms an important part of the limbic system, the region that regulates emotions
the frontal lobe
where most of our personality hangs out. It is involved in the ability to control our emotions and abstract thought
Most of the parietal lobes are made up of association areas
the occipital lobes are responsible for our eyesight
Trichromatic and opponent processes theories of color detection
human visual system interprets information about color by processing signals from cones and rods in an antagonistic manner
How do visual feature detectors work? (see Hubel and Wiesel study)
showed that if a kitten is deprived of normal visual experience during a critical period at the start of its life, the circuitry of the neurons in its visual cortex is irreversibly altered.
which states that every stimulus is perceived in its most simple form
Basic roles of the outer ear
pinna, the part you can easily see and feel, and the ear canal. The pinna helps to gather the sound waves around us. These sound waves travel down the ear canal where they strike the ear drum. The ear drum separates the outer and middle ear
is an air-filled, membrane-lined space located between the ear canal and the Eustachian tube, cochlea, and auditory nerve
the semicircular canals which serve as the body's balance organ and the cochlea which serves as the body's microphone, converting sound pressure impulses from the outer ear into electrical impulses which are passed on to the brain via the auditory nerve
a wavy strand of muscle that bends at certain frequency and hair cells- mechanical levers that bend at certain frequencies
the hair cells bend at the certain frequencies
where the frequency corresponds with the flexibility of the basilar membrane
How do we localize sounds?
Speed, how loud the sound is
Dichotic listening (studies by Cherry; Triesman; and Conway et al)-
psychological test commonly used to investigate selective attention within the auditory system
Activation Synthesis Model of dreaming
this theory suggests that the physiological processes of the brain cause dreams.
process of responding to a stimulus similar to but distinct from the conditioned stimulus
the ability to perceive and respond to differences among stimuli
Sperling's partial report procedure
he showed support for his hypothesis that human beings store a perfect image of the visual world for a brief moment, before it is discarded from memory

Define each of these terms: (a) angle of incidence (b) angle of refraction (c) focus (d) magnification (e) mirage (f) virtual image
The neuron (nerve cell) has a long extension called an axon. Molecules made in the cell’s main body must travel a long distance to reach the end of the axon. The axon is lined with microtubules. Explain how motor proteins, vesicles, and microtubules move these molecules along the axon.
About 97 percent of the hydrosphere is (a) salt water in lakes, seas, and the ocean (b) water vapor in the atmosphere (c) fresh water in ice and snow (d) also part of the cryosphere
Write a balanced chemical equation for each of the following reactions. Include state symbols. Classify each one as either synthesis or decomposition. (a) Hydrogen gas reacts explosively with chlorine gas to form hydrogen chloride gas. (b) A solution of hydrogen peroxide, $$ H_2O_2 $$ , breaks down into water and oxygen. (c) Solid potassium chlorate breaks down into solid potassium chloride and oxygen when heated. (d) Ammonia gas, $$ NH_3, $$ can be made by combining hydrogen gas and nitrogen gas. (e) Aluminum metal reacts with oxygen from the air to form a hard coating of aluminum oxide. This coating prevents aluminum objects from corroding.
