Study Notes
Module 4 Learning Objectives
- Identify and describe various brain disorders
- Map affected brain regions
- Describe how damage affects brain function
Brain Lobes + Disorders
-
Visual brain areas process visual information
-
Regions include primary visual cortex
-
Akinetopsia
- Inability to perceive motion
- Visual perception of static frames
- Caused by damage to V5 (Middle temporal visual area)
- V5 function: motion perception
-
Achromatopsia
- Cortical colour blindness
- Sees world in greyscale
- Functional optic nerves
- Caused by damage to V4 (Occipital lobe)
- V4 function: color perception
-
Prosopagnosia
- Inability to recognize faces
- Intact vision
- Caused by damage to FFA
- FFA function: face recognition (temporal lobe)
Module 2 Learning Objectives
- Recognize and label brain regions (lobes, primary areas, limbic system)
- Map functions to brain regions
- Identify neuron parts and describe function
- Describe neural communication
- Outline brain function measurement methods
- Explain neuroplasticity
Lobes of The Brain
-
Frontal lobe:
- Decision-making, problem-solving, planning, voluntary movement, speech production
-
Parietal lobe:
- Sensory perception, spatial orientation, touch processing
-
Occipital lobe:
- Visual processing
-
Temporal lobe:
- Hearing, memory, speech comprehension
Module 3 Learning Objectives
- Visual brain concept
- Primary visual cortex mapping & functions
- Functional modularity concepts
- Selective visual deficits
- Differences between attention/awareness
- Explain "blindsight"
Primary Visual Cortex
-
Located in the occipital lobe
-
Processes visual information from opposite visual fields
-
Responsible for initial visual processing (edge detection, motion)
-
Damage to primary visual cortex causes blindsight
-
Blindsight: Responds to visual stimuli without conscious awareness
Functional Modularity
- Specialized brain regions dedicated to specific functions
- Examples include Broca's area (speech production), Wernicke's area (language comprehension), V4 (colour perception), FFA (face recognition)
Signal Detection Theory
- Measures decision-making under uncertainty
- Assessing ability to distinguish signal (stimulus) from noise (background)
- Considers sensitivity to signal and response bias
McGurk Effect
- Visual information (lip movements) alters auditory perception
- Brain integrates sensory information to create a "best guess"
Cortical Scotoma
- Partial vision loss (blind spot) in visual field
- Damage to visual cortex
Methods to Measure Brain Function
- Electroencephalography (EEG)
- Functional magnetic resonance imaging (fMRI)
- Others (not listed)
