The LEFT hemisphere

1) The brain's process of organizing and interpreting sensory information to give it meaning (learned); 2) The process of receiving stimulus energies from the environment.
1) Perception; 2) Sensation

Since both men and women process verbal information much differently, MRI studies have found that women process language on _____________ hemisphere(s) and men process language on _____________ hemisphere(s).
both; left

1) If my friend Arianna can see the seven colors of the rainbow after a sudden rain shower that occurred, what kind of photoreceptors are in effect? 2) If I can't see the red color of a mustang during the night, what photoreceptors am I manipulating in this case?

In what stage of sleep do night terrors occur?
Stage 4

Mark and Michael both found out that they scored exactly the same test score which is a 90/100. Twin studies do show that their IQ's are quite similiar. The mean (M) of the entire class was 75% on Exam #2 and the standard deviation (SD) is 5. What are there individual raw scores? What are Mark & Michael's individual z-scores?
Mark's raw score= 90; Michael's raw score= 90; Mark & Michael's z-score= +3.00; left hemisphere responsible for logical/critical thinking/math

Dr. Roberts mentioned to one of her students, "How are you going to turn in your homework assignment to me if you aren't going to show up to class on Friday?" The student responds with no answer and can't seem talk at all." This student is displaying what type of aphasia?
Broca's Aphasia

Draw out and label the parts of a light/sound wave. Indicate the degree of light/sound wave of each in terms of amplitude.
Higher amplitude= Brighter Light; Lower amplitude= Dim Light; Higher amplitude= Loudness; Lower amplitude= Low/Soft pitch

Homer Simpson said outspokenly, “Where can I find more Duff beer?” The store owner of Kwik-E-Mart (Apu) responds, “Thank you, come again!" Apu is displaying what type of aphasia?
Wernicke's Aphasia- can't understand verbal communication, but able to produce fluent speech (word salad; non-sensible)

This is the theory in which the human eye contains three types of color receptors (red, green, and blue), which form the basis for our perception of all colors- these colors cause the cones to fire.
Trichromatic Theory of Color Vision or (Component Theory- "Young-Helmholtz")

Foods/drinks such as chocolate, soda, and tea..etc. are what types of drugs and what neurotransmitters are released from them.
Caffeine (stimulants- releases dopamine)

Microsleeps

Demonstrate a role play conversation of Broca's Aphasia & Wernicke's Aphasia.
"Aphasia"- damage of... Broca's Aphasia- can understand/comprehend language, but can't produce speech; Wernicke's Aphasia- can't understand verbal communication, but able to produce fluent speech (word salad; non-sensible)

In a laterality study involving the split-brain patient V.J., a chimeric stimulus was presented, involving half of a young woman's face on the left, and half of an older man's face on the right. V.J. verbally reports that she sees an old man because _______________________________________________ . When asked to draw with her left hand, V.J. _____________________________________ .
speech production is lateralized to the left hemisphere of the brain; draws a sketch of a young woman.

Elwald Hering theorized that six primary colors (red, green, blue, yellow, black, and white) are grouped into three pairs: 1. One receptor (the black-white pair; contributes to our perception of brightness and saturation) 2. Other two receptors: Red-Green and Blue-Yellow pair; responsible for our perception of color

Involves brain abnormality of the basal forebrain and amygdala in which the person may fall into REM sleep without warning, experience a loss of muscle tone- goes into REM cataplexy, and losses consciousness. (Hint: Video on "DOG")
Narcolepsy

Explain the left & right visual fields in relation to both left & right hemispheres (functions). Provide an example to explain concept.
If I can see an apple on my right visual field, it will be processed to the left hemisphere. Therefore, I can name the object (apple). However, if I can see an apple on my left visual field, I wouldn't be able to name the object since language isn't specialized in the right hemisphere. In this case, I can only draw out the apple since the right hemisphere controls creativity, imagination, and mental/perceptual images.
