31

Reticular formation

Network of neurons that extends from the spinal cord, through the hindbrain and midbrain. Plays a role in the sleep/wake cycle, arousal, attention, pain, and touch.

32

Ventral Tegmental Area (VTA)

Group of neurons in the base of the midbrain, which are involved in the reward system of the brain

33

Red Nucleus

Involved in movements such as arm swinging while walking and crawling in babies.

34

Substantia Nigra

Contains a large number of dopamine-producing neurons, associated with voluntary movement and motor planning

35

Inferior colliculus

Receives sensory info fromt he ear and relays auditory stimuli

36

Superior colliculus

Process info related to visual stimuli and is associated with eye movements

37

Tritanopia

Equally prevalent in males and females; difficulty perceiving short wave lengths (blue and yellow) because retina lacks blue cones; sees reds and greens normally, however sky is green and yellow objects look pink

38

Deuteranopia

AKA second color deficit; confuse green and red; remainder of color cision normal. More common in males. (Green cones are filled with red spin).

39

Protanopia

AKA first color deficit; they have good acuity in short wavelengths (blue and yellow) but lose color perception at higher wave lengths; confuse reds and greens as they look yellowish; more common in males

40

Color agnosia

Condition in which one is unable to associate a color with a particular object; a person with this condition may not know what the color of an elephant is

41

Color anomia

Inability to name colors one sees. Not a visual problem, but a problem with verbalization and word-finding

42

Damage to V5

Loss of ability to see movement. Can see still objects, but object will disappear if it begins to move

43

Damage to both V3 and V4

Complete loss of form perception

44

Damage to V4

Loss of ability to perceive color, known as cerebral achromatopsia. See the world in shades of gray. Dyschromatopsia refers to partial loss in color perception and is more common

45

Damage to V3

Partial loss of form perception

46

Damage to V2

Global disruptions in vision, with impairments in ability to distinguish form, movement, color, and spatial orientation of patterns

47

Damage to V1

Most serious of visual impairments. Partial blindness in both eyes. Blindsight: a condition in which patients report seeing nothing, but respond to change in visual field, such as movement, due to visual processing still occurring at lower levels.

48

Homonymous hemianopia

Damage to the optic chasm will affect input from one half of our visual field from both eyes, thereby causing bilateral heminaopia that affects one medial and one lateral input

49

Heminaopia

Blindness in part fo the visual field caused by damage to either optic nerve. Damage to the medial optic nerve at optic chasm leads to loss of vision in temporal half of both eyes, or bilateral hemianopia.

50

V5 area

Critical for the detection of form while in motion

51

V4 area

Function is primarily color processing, although some cells within V4 respond to both form and color

52

V3 area

Predominantly devoted to form perception

53

V2 area

Sends visual projections to lower visual areas. Heterogenous with V1 in function, performs some color, form, and mvmt processing and processing spatial info

54

Primary visual cortex

AKA - V1 and striate cortex. Largest most important visual area. All visual input comes here first then projected to the other occipital areas. responsible for perception of sight.

55

Vision and occipital lobe

Lateral inputs are projected to the anterior portion of the occipital lobe. Medial inputs are directed to posterior portions of the occipital lobe

56

Implicit memory

Basal ganglia (caudate nucleus and putamen), globus pallidus, thalamus, substantia nigra, and cerebellum

57

Explicit memory

Located in the temporal lobe and include: hippocampus, amygdala, temporal cortex. These structures connected through the thalamus to the prefontal cortex

58

Occipital lobe

Involved with the brain's ability to recognize objects. Responsible for vision.

59

Temporal Lobe

Responsible for hearing, memory, meaning, and language. Plays a role in emotion and learning. Concerned with interpreting and processing auditory stimuli.

60

Parietal lobe

Connected with processing of nerve impulses related to the senses; touch, pain, taste, pressure, and temperature. Also have a language function.
